Added icons to game buttons.
11-09-2025 - Gungnirdarts-app - 149, 1.1.142.0
Removed player selection from arcade games. Now you don't have to select a player before starting an arcade game. Whenever you reach a highscore, you can enter your name. Just like in the arcades. The last entered name is stored and shown as default when entering a highscore.
Player selection for classic games has also changed. When selecting a player in a team, you can now also press "Create or Search" at the bottom of the screen and enter a name. The player is then created if needed and added immediately to the team.
03-09-2025 - Gungnirdarts-app - 148, 1.1.141.0

Gen-4 now comes with an improved calibration tool to replace the current black arrow.
Removed camera height check from full calibration routine. This caused too much confusion.
The diagnostics pdf has been reduced in size dramatically for downloads via Bluetooth. It also makes it easier to check if your cameras are at the right height.
08-07-2025 - Gungnirdarts App - 145, 1.1.139.0
Added initial support for OBS (Open Broadcaster Software). The Gungnirdarts App can call the OBS websocket to change scenes on Dart Removal and Dart Detection. It can be configured in the Settings..OBS screen. On Dart Detection and Removal detection events different scenes can be shown.
Added a Factory Reset option to the Settings...Gungnir Dartstracker menu at the bottom of the screen. This resets the configuration of the dartstracker to the initial settings. Useful when somehow the current configuration is not working anymore and the dartstracker keeps failing calibration.
The current Darstracker version is now shown on the Settings...Gungnir Dartstracker screen.
Added Bounce to score correction screen to register a Bounce Out. This fixes an issue where a correction was sent to the dartstracker when manually correcting to a miss when a bounce out was meant.
Updated default configuration to improve detection of 'Thicker' and 'Shinier' darts.
Added a Factory Reset option to the Bluetooth stack. It's now possible to reset the dartstracker configuration to factory defaults from within the Gungnirdarts App. Both the Dartstracker and the App need to be updated to to let this work.
29-06-2025 - Gungnirdarts App - 143, 1.1.137.0
Added Ranking lists to Dartskin games.
Fixed a bug in Flying Lap Dartskin when 2 players both throw 'Slow down' in consecutive turns.
Fixed a bug with the calibration of the Dartskins causing AI opponent throws to be invisible.
26-06-2025 - Gungnirdarts App - 142, 1.1.136.0
Fix for no darts shown when playing an AI opponent with Dartskins when there was a calibration offset set for the Dartskin.
Fix for an issue when changing a player in a team wasn't shown in the team view, but it was shown in the all Teams view.
22-06-2025 - Gungnirdarts App - 140, 1.1.134.0
When playing Dartskins games with automatic scoring it's now possible to calibrate the darts position on the Dartskin manually by pressing the settings icon at the right bottom of the Dartskin. Throw 3 darts at at the board and move the dots with the arrow buttons until they at the same position as the darts on the real board.
Fixed a bug where enabling Skip Full Calibration check in the Settings...Gungnir Dartstracker...Configuration screen wasn't saved.
14-06-2025 - Gungnirdarts App - 139, 1.1.133.0
Fixed Match Result issue in Power Shootout. Also changed power of shot areas. Outside triple is now, normal power shot, inside triple is double power. And bull is ultra power automatically targetted on goal.
11-06-2025 - Gungnirdarts App - 138, 1.1.132.0
Updated used frameworks. This includes a fix for the text-to-speech engine not working when 'Use System Language' is used in the Android Text-To-Speech settings.
Added online matchmaking and private games for Dartskins for players with and without a Dartstracker.
Online classic games now also possible for players without a Dartstracker. Manual entry of every dart is required.
For all third party API users : Fixed an issue with Wifi networks with SSID's with spaces that couldn't be joined. Mind the system doesn't need wifi to function just bluetooth. This is for anyone wanting to make third-party apps to connect to the system.
Debug or verbose mode can be set manual or from the System...General menu and is stored in configuration parameter C207
This update doesn't contain a new software version, but only a small configuration change needed to support newer cameras. When your Dartstracker works fine at the moment with its current software version, there is no need to upgrade to this Rev-2. But when you've just build your DIY Dartstracker and somehow calibration keeps failing, try this Rev-2 image.
18-05-2025 - Gungnirdarts App - 135, 1.1.129.0
All classic games like X01, Cricket and Round the clock are now playable online. The Main Menu item "Online Games" has been removed and Online Play is moved to the Match Setup menus of the individual games themselves. Mind that Online matches are always best of 3 legs, if a match can't be found with your specific options, opponents with other options will be matched also.
Online play now requires that both players use the latest version of the app. So if you are unable to find opponents, check if you are running the latest version.
09-05-2025 - Gungnirdarts App - 133, 1.1.128.0
Updated the Match Setup screens with a more touch friendly look. Now also including game instructions on the setup screen.
Moved Killer to Classic games
Maintenance framework updates
01-05-2025 - Gungnirdarts App - 132, 1.1.127.0
Added a new category to the Arcade games called Action Arcade. It contains the beta of a game called "Power Shootout" where you have to score a goal by moving the ball between opponents and passed the goalkeeper.
Fixed a second issue with the virtual board shown when playing online when 2 players with different locales played each other. Both players need to have updated to this version to solve the issue, so it might be that after updating you still seem to have the issue if your opponent hasn't updated yet.
25-04-2025 - Gungnirdarts App - 131, 1.1.126.0
Fixed an issue when starting an online match there is a short popup glitch, but nothing happens.
All players now connect to the same server, sometimes players connected to regions where there were no players, which was kinda lonesome.
13-04-2025 - Gungnirdarts App - 130, 1.1.125.0
Added a new Dartskins menu under the Arcade menu with currently 2 Dartskins supported, the Flying Lap and Eight-Ball Dartskins to try out. For autoscoring the custom Dartskins Clamp is required for the best detection, but without autoscoring they can also be used as a Manual Scoreboard for the Dartskin. Checkout the features on the homepage for more info.
UI Button restyling, less XBoxy.
Menu renaming, High score, Bull Power scoring and Killer now fall under Classic Arcade.
Fixed a bug where opponents darts were not shown on the virtual dartboard.
Fixed an issue with removal detection which sometimes caused false detections when taking out darts. This also improves the overall removal detection speed.
The minimum number of cameras required to decide on removal is now configurable in the System..Detection menu or config item C204.
The minimum number of cameras required to decide on a detected dart is now configurable in the System..Detection menu or config item C205.
The maximum mm difference in distances to bull when calibrating board dimensions is now configurable with config item C206. Default is 10 mm max difference.
Added "Toggle Debug" button to System General menu to log more information and store images in /boot/images on SD-Card. When using this, make sure to empty this directory once in a while.
18-02-2024 - Gungnirdarts App - 127, 1.1.121.0
Fixed an issue in cricket where all scores were yellow.
Added highest score indication when playing with more then 4 players in cricket.
14-02-2025 - Gungnirdarts App - 126, 1.1.116.0
Changed UI to accomodate for matches with max 8 teams of max 2 players.
Changed the way players and teams are selected for matches.
Cleaned up match UI
05-02-2025 - Gungnirdarts App - 125, 1.1.115.0
Fixed an issue where the app wouldn't start on Windows. This required to disable PDF generation functions in the Windows app. So the QR-Code pdf generation and the Detailed Matchstats PDF, which can be downloaded by pressing the Details button on the Match Statistics screen after a match are only available on Android.
30-01-2025 - Gungnirdarts App - 123, 1.1.113.0
Added Checkout Rate and Avg. Nr Of Throws to the player's aggregated X01 statistics.
Added the option to generate a detailed PDF match report to the Match Statistics screen for X01 matches by pressing the Details button at the bottom which includes more detailed match statistics like a leg breakdown, and in case of multiple legs, an average scoring graph per leg.
Every throw of a player is stored in the database. These throws can now be downloaded in a CSV file in the Player...More options...Download Throws menu for creating your own dashboards. The default storage time for a throw is 1 day to prevent storage issues, if you want to keep them longer change the Settings...General..Long Term Dart Storage option to On.
Possible fix for keeping the tablet screen on during play.
Fix for MPR calculation in Cricket and Tactics.
Added Round indicator in Cricket and Tactics.
Average Cricket, Tactics & Shanghai MPR is now shown in Overall Player Statistics.
25-12-2024 - Gungnirdarts App - 121, 1.1.111.0
Fixed an issue where the app crashed when linking the app to a Dartstracker for the first time with a password.
23-12-2024 - Gungnirdarts App - 120, 1.1.108.0
Added private online matches to the random matchmaking. When starting a private match a room name is asked. When 2 players enter the same room they play each other. To meet or find specific players the channel find-opponents can be used on the Gungnirdarts discord
The empty board detection has been improved, making sure that when all darts have been removed from the board without a hand triggering the Removal, the removal is triggered when the board is empty.
Fixed an issue in the removal detection algorithm where darts that are removed without triggering a removal were counted again. This fix probably also reduces false dart detections triggered just before removal due to fingers or other artifacts.
10-12-2024 - Gungnirdarts App - 119, 1.1.107.0
Fixed bug where board reset before a match is only required one time instead of every match.
All the calibration routines can now be executed with the surround on the board, but only if the surround has a lower or equal height compared to the edge of the board.
When executing a Full (Complete) calibration this means that the surround can stay on the board and only the number ring has to be taken of. When executing the Quick calibration (when the app starts) the surround and number ring can both stay on the board.
When starting calibration routines individually the surround and number ring can stay on the board for the Board and Sector calibrations. The surround can stay on but the number ring needs to be removed for the Detection Area and Camera Height calibrations.
When calibrating the ROI no images are saved to the SD-Card anymore this reduces the chance of corruption of the sd card and also speeds up some parts of the calibration.
Changed hitpoint detection algorithm to not only account for biggest cluster but also largest confidence in rays. Also fixed a bug where sometimes not all rays were cleared between throws.
Changed default FOV of cameras to 64.5. In combination with the zoomfactor of 1.4 the distances the Dartstracker determines come closer to the real distances. Mind that due to lens distortion the found distances to the bull of certain hitpoints can be different from the real life distances. That's why the board calibration still is important and needs to be executed.
The Board calibration now determines specific sector values for all sectors by extrapolating the found values for the 20,6,3 and 11 sectors.
Configuration and logic changes to reduce the chance of a dart not being detected. This was usually the third dart.
Minor change in removal detection logic and configuration values, for the case when first a finger was mistaken for a dart and then movement transformed into a removal. This also resulted in faster Detection overall.
The Detection Area Calibration (ROI) takes a bigger margin from the top of the ROI to reduce ledstrip interference on shiny darts.
Configuration item C200 is used to register if a full calibration has been executed succesfully once. The app checks this value to determine if it asks the user to execute the Full Calibration.
The app checks if the board has been fully calibrated when the app starts and asks to do this if this is not the case. This question can be disabled in the Settings...Gungnir Dartstracker...Configuration screen.
The Full Calibration now goes to the Free Practice mode after finishing the calibration to let the user check the accuracy and make score corrections if necessary.
When connected to older versions of the dartstracker the app can't ask the dartstracker but checks if this is the first time you connect to a dartstracker and asks for a full calibration.
In the Settings...Gungnir Dartstracker...Configuration screen the Quick Calibration, Sending of corrections and Full calibration check can now be enabled/disabled.
Mind that the latest versions of the Dartstracker software don't require the surround to be removed anymore for calibration.
Changed the Fast Calibration routine to only execute the Center calibration. The ROI finetuning method caused too many calibration errors.
Disabled the method of dealing with reflections by default. The threshold was too low causing too many calibration errors. It can be enabled by setting configuration property C199 to True. The threshold can still be set by altering C198. When enabled the default is 254 now, it was 240.
Fixed an issue in the Quick ROI detection algorithm that made all ROI's the same size. Mind that due to a new method of dealing with reflections, the ROI detection may fail while it used to work. Check your ledstrip to make sure it's not loose and causing reflections on the inside of the ring. If it keeps failing you can disable the reflections algorithm by setting configuration property C198 from 240 to 255. Do this via the System..Backup menu on the webinterface of the Dartstracker by downloading/changing and uploading the config or by changing the configuration in the /boot/defaultconfig.json file on the sd card
22-11-2024 - Gungnirdarts App - 116,1.1.105.0
Changed Free Play to show the dartboard with the detected throws at the right.
Added Free Play at the end of the "Complete Calibration" routine to check your calibration.
Improved the ROI detection algorithm to better deal with the ledstrip distortion.
13-11-2024 - Gungnirdarts App - 115, 1.1.104.0
Added a "First time connect check" to direct user directly to the "Complete Calibration" when connecting to a Dartstracker for the first time.
Added "Quick Calibration" after the app finds a Dartstracker to calibrate the ROI and the dartboard center without having to remove the surround or number ring. This functionality requires the Dartstracker also to be updated to the latest version! If this calibration doesn't work for you, it can be disabled in the Configuration Menu mentioned below.
Added a Configuration Menu to the Gungnir Dartstracker menu with options to enable/disable the Quick Calibration and Sending of Manual Corrections to the Dartstracker. Enabling corrections on the Gungnirdarts app will only work if "Process corrections from the client" on the Dartstracker is also enabled. On the latest version of the Dartstracker this is enabled by default.
When linking a Device to a Dartstracker through Bluetooth, a password is now registered in the app and on the Dartstracker. When other Gungnirdarts Apps try to connect through Bluetooth after this they need to enter the same password to link otherwise they will be denied access. This functionality requires the latest version of the Dartstracker and Dartstrainer.
Moved Dartstracker Statistics from the Gungnir menu to the Command bar.
The version of the Dartstracker is retrieved via bluetooth and shown when starting.
Optimized Dart Detection routine for faster and more accurate detection. Keep in mind that direct sunlight on the board or inside of the sideplates might trigger false detections due to bright spots and reflections.
Added a new Quick Calibration routine that doesn't require the surround and number ring to be removed. It will be run when starting the Gungnirdarts App to finetune and make small corrections to the current calibration settings, compensating for small camera movements. This requires the Dartstracker and Gungnirdarts App to be updated to work. The surround may not be higher then the dartboard (about 3 cm) for this calibration to work.
The password of the linked Device is now stored in configuration item C196 of the defaultconfig.json. In case of emergency when the password is forgotten, resetting this to "" makes the Dartstracker available for linking to another Dartstracker again. For this purpose an Unlink Button is also added to the web interface in the System..General page.
Added a Configuration Characteristic to the Bluetooth stack. This makes it possible for the Gungnirdarts App to make configuration changes and get configuration settings from the Dartstracker. Setting configuration items via Bluetooth can be disabled by setting property C195 to False in the defaultconfig.json file of the dartstracker. This also freezes the current state of linking when you don't want
Changed "Default dart distance to wire" for calibration to 1 mm instead of 1.5 mm
Moved "Process corrections from client" checkbox from the Board settings to the Calibration settings menu. This setting is now True again by default.
30-10-2024 - Gungnirdarts App - 114,1.1.102.0
Fixed timeout issue in online games.
28-10-2024 - Gungnirdarts App - 113,1.1.101.0
Added Rematch option for Online matches.
Online Matchmaking based on the 3-Dart Avg of the last 3 months or anyone if no opponent found.
The 3-Dart Avg of the last 3 months is shown after the player name in Online matches.
23-10-2024 - Gungnirdarts App - 111,1.1.99.0
Added a remote board view for Online opponents and AI-Opponents which shows the exact position of the thrown darts of your opponent. It is On by default but can be disabled if needed in the Settings menu.
New online gameplay via cloudbased MMO server, starting with 501 best of 3 legs. Start games without leaving the app or the need for a browser. This means we will shutdown the lidarts server, but our lidarts server code is available in the downloads section to host your own server and the option to play via this server (and setting a server url) can be enabled in the app settings. This to make sure there is always an option to play online via Gungnirdarts via your own hosted server. Other Dartscounters certainly don't offer this option :-)
Performance improvement for first dart detection between turns due to changed lighting conditions algorithm.
Added sector indications to camera logging.
Adjusting the calibration by processing corrections from a client is now disabled by default. Enable via the webinterface (System...Board) or changing property C175 to true in the defaultconfig.json on the /boot partition of the sd-card.
The camera height check now also checks if the cameras are in focus. An In Focus threshold value is added to the Cameras...General screen. The current value determined by the algorithm is shown on the specific camera screens.
11-06-2024 - Gungnir Dartstrainer - 105,1.1.86.0
Maintenance update. Updated all frameworks to latest versions.
Fixed bug in Settings..Online screen.
02-06-2024 - Gungnir Dartstrainer - 102,1.1.85.0
Added online play to the app via our own server on https://play.gungnirdarts.com. Lidarts is still available on Android (activate from Settings screen), but unsupported. Nakka has been removed due to unresolvable API changes.
12-05-2024 - Gungnir Dartstrainer - 99, 1.1.83.0
Player selection screens updated to handle longer player names.
02-05-2024 - Gungnir Dartstrainer - 97,1.1.82.0
UI Change. The menu list screens have been replaced by block screens. No more scrolling, just tapping.
A new attempt with an image that now uses a non-writeable OS to reduce chances for SD-Card corruption. The /boot partition remains writeable to store configurations. This version can not be updated to via the webinterface, a new sd card image is needed to run this version. If you do update via the webinterface you'll get all the updates except for the non-writeable OS.
In case of a configfile corruption the system will now use the last backup of the configuration file.
The dartstracker now includes a commercial licensing option. Contact us for more info. If you have downloaded the gen-2 image before 19-03, please download it again, it could be the gen-1 version.
14-03-2024 - Gungnir Dartstrainer - 92,1.1.73.0
From now on the Android and Windows versions will be submitted to the stores at the same time for updates. Whenever the Android version is approved this page will be updated. The Android Playstore approval usually takes a few hours, while Windows Store approval can take 24 hours or more. So for the windows update you might need to be more patient. You can check if the update is available by the version numbers, 92 is the new android version, 1.1.73.0 is the new windows version.
Added a 'Confirm legshot' confirmation to Local Games before the leg really finishes. This to prevent the leg, set or match finishing when the darts have been removed already, but a correction still had to be made. This option is default on, but can be switched off in the Settings..General menu.
Improved bluetooth searching by adding a cache for already discovered boards.
06-03-2024 - Gungnir Dartstrainer Windows (Beta)
Beta Windows version of the Dartstrainer app available via the Windows Store. This version doesn't have the online lidarts or nakka functions, just the offline functions. To download use the "Download for Windows" button on the Dartstrainer feature page.
29-02-2024 - Gungnir Dartstrainer - 88
Fix for Round The Clock match crashing the app after finishing.
28-02-2024 - Gungnir Dartstrainer - 87
Maintenance release, updated frameworks the app uses to latest versions and latest Android version.
Fix for a default storage path change in Android which results in a new empty database in that location. Updating to this version will use the old location again so you will have your old players and stats back. This means that anyone who started using the app the last 2 days will lose their current players and stats of the last 2 days.
Fixed a bug where linking a dartstracker from the main menu, still returned the first board found when starting the app.
Added another camera rotation calibration method that is now the default used. It's more robust and not influenced by lights from outside, but it requires a dartboard with a black side. If the old method of detecting the camera rotation was working better for you, you can switch between the old and new method in the System...Calibration menu.
10-02-2024 - Gungnir Dartstrainer - 83
Added new practice game called Highscore. Get the highest score with a certain number of darts and get ranked in the ranking list.
Update for Gen 2 that changes the configuration of some parameters to be inline with Gen 1. The FOV parameters are set to 65 degrees instead of 69. The postprocessing parameters are also altered to be the same as Gen 1. This is to reduce detection errors on the lower board area. (double 3, 19, 17 etc). After this update a Complete Calibration is necessary.
ROI Calibration adjustment to reduce calibration errors.
QR code PDF generation in the bluetooth menu adds the name of the board to the print.
03-02-2024 - Gungnir Dartstrainer - 82
Added a practice mode in which games can be played for which offline highscore lists are kept. To start of one game is added called Bull Power Scoring instructions are in the app. Also a free practice mode is added in which you can just throw without rules.
22-01-2024 - Gungnir Dartstrainer - 77
Added several X01 stats that are tracked daily for every player. You can find them in the Players...Statistics screen. Select a player and then press statistics.
Added a 'Restore Last' button to System..Backup screen. This will restore the last configuration used before the current one. Very handy in case of a corrupted configuration file.
Added a Test screen to the System menu with buttons to generate dartstracker events (Removal Start, Removel End, Detected Throw) to test connected services via the API.
The Reset Background button on the Tracking Screen sometimes had to be clicked twice to work. This has been fixed now.
A 'Post detection delay (ms)' setting has been added to the System..Detection screen. This pauses the detection after a dart has been detected to wait for a stable image.
29-12-2023 - Gungnir Dartstrainer - 76
Some layout changes to the Dual Match View.
Added Nakka (Beta) as an option to play online next to Lidarts. Playing on Nakka only works with an X (Twitter) account at the moment, Facebook and Google accounts don't work.
Fixed a bug where the score correction board was not scaling right.
23-12-2023 - Gungnir Dartstrainer - 75
Added dual view for X01 and RTC matches between 2 players/teams. Matches between 1, 3 or 4 players/teams still show the player to the left and scoreboard to the right.
22-12-2023 - Gungnir Dartstrainer - 74
A change for the correction procedure of a throw. First you still tap the throw to go through the closest alternatives. But now, if no alternatives are left a special board is shown, where you can select your throw manually.
18-12-2023 - Gungnir Dartstrainer - 73
Fix for the Back button not working when playing with 1 team.
Changed some timings while processing images which should result in improved accuracy.
09-12-2023- Gungnir Dartstrainer - 72
Renamed remember board button and forget board button at the bottom of the main menu to link and unlink. When the dartstrainer is linked to a board it will automatically try to connect to that specific board when it starts up.
The Search and Scan buttons will not be shown when starting the app and a board is linked.
A rematch button has been added in the statistics screen after a match. Statistics will be reset after Rematch is chosen.
Fixed a bug when restarting the app with the button in the main menu crashes the app.
When a configuration change is made a copy of the current configuration file is made first in the /boot directory called defaultconfig.json.old then the new config is written to defaultconfig.json. When the config file gets corrupted you can always rename the .old file and get your old config back. The boot directory is accessible from the sd card when inserted in a windows machine.
Only the first dart of a turn is used for corrections of sector dimensions and board rotation.
Fix for long duration of the first time "Connecting to board" message at start of match. This fix requires updates of both the dartstrainer & dartstracker.
Fixed accuracy issue regarding the dart detection delay time.
17-11-2023 - Gungnir Dartstrainer (Android) - 63
Added option in main menu to remember/forget the connected dartstracker. When a dartstracker is remembered the app will automatically connect to it when starting up.
Fixed bug where old diagnostics pdf was not overwritten.
09-11-2023 - Gungnir Dartstrainer (Android) - 61
Added option to download diagnostics pdf via bluetooth in the Settings menu. This function needs at least version 1.0.8712.20883 of the dartstracker. Mind that this is much slower compared to downloading via webinterface.
BUGFIX: After correcting a triple to a single, no triple is detected.
Added automatic board rotation correction when correcting from the dartstrainer
Added a board rotation parameter to the board settings. The board rotation is reset when 'Reset all sectors' is chosen when doing sector calibration from the dartstrainer.
Added reinforcement learning, processing the correction data that comes back from the dartstrainer and changing the specific sector calibration values. In the System..Detection page this functionality can be enabled/disabled if needed. Mind that this needs version 60 from the dartstrainer or later.
Added sector calibration routine to calibrate specific sectors. These values will overrule the default values found by the board calibration and are adjusted by the reinforcement described above if activated.
Fixed the camera height calibration page and calibration routine.
29-10-2023 - Gungnir Dartstrainer - 60
Important: If the dartstracker isn't updated to the latest version. Only the Complete Calibration can be used from within the dartstrainer. The other calibrations will not work.
Corrections are now communicated back to the dartstracker as reinforcement learning data.
Added Sector Calibration screen. See dartstracker update above.
23-10-2023 - Gungnir Dartstrainer - 58
Calibration has been split up in 3 routines. Camera height, Detection Area, Board Dimensions and Complete calibration which executes all 3 in order. This way you can execute a part of the calibration without always having to go through the full routine. Each calibration routine also gives more information on it's calibration page. You can find the routines in the Setup...Gungnir Dartstracker..Calibration menu. For this to work the dartstracker should be updated to the latest update which is at this time : 1.0.8696.20122. Otherwise only the complete calibration will work.
Added extra logging listing the available video devices.
There are now 4 calibration routines. Camera Height, Detection Area, Board Dimensions and Complete calibration. Camera height helps with setting up the cameras at the right height. Detection Area calibrates the ROI, board surface, camera rotation and board center. The board dimensions calibration finds the distance of all the sectors to the center for your board. The Complete calibration executes the former 3 calibrations in order. This way you don't have to execute the complete calibration everytime. These calibration options will also be added to the next update of the Dartstrainer app.
Camera Height Calibration moved back to Calibration menu and more info added to the page.
The Calibration Settings page gives the option to indicate which steps the Detection Area calibration consists of. If for any reason one of these steps fail for your setup, you can disable it here and set it manually.
Faster detection (Down to an average of around 30 ms on RPI-4).
Camera Height Calibration is moved from calibration to the initial Setup.
Camera Height Calibration is changed to give more information on how to get the height of the cameras right.
Improved camera handling when a device is in error. Trying to reset the device before erroring out.
Moved calibration and detection settings to the System menu.
When updating to this version the detection settings are changed to default values for this version. You can change them again manually after updating if necessary.
Added FPS setting to Cameras...General to set the framerate of the cameras.
Added Nr of parallel processing cameras setting to System...Detection settings. To set the maximum nr of parallel processing threads for capturing and processing camera streams.

The application is updated to use the latest frameworks.
Overall application speed improved due to more caching upfront.
Due to framework updates, had to rewrite the bluetooth code. It seems to be faster and more stable now.
The name of the board that the dartstrainer is connected to is now shown at the bottom.
