RaceChrono v7.4 beta

edited November 2021 in RaceChrono for Android
I've just released RaceChrono v7.4 for Android to the beta group ( https://racechrono.com/article/faq/how-do-i-join-the-beta-group ).

This is another minor release to fix the most urgent bugs in the previous version. This release also includes the new Monitor API that can be used to create an external display device for example.

Change log for RaceChrono v7.4.0:
- Added Bluetooth LE Monitor API for the RaceChrono DIY device
- Fixed: Issues with standing starts
- Fixed: Problem with multi-frame OBD-II responses
- Fixed: Missing picture-in-picture placeholder in Overlay editor
- Fixed: Picture-in-picture option for export may become hidden

Change log for RaceChrono v7.4.1:
- Fixed: Wrong lap displayed in analysis when opening a single sector for a reference lap
- Fixed: Wrong timer information on video overlay when a reference lap was analysed

Change log for RaceChrono v7.4.3:
- Added full Android 12 support
- Improved: Connections now recover when Bluetooth is turned off and on again
- Fixed: Time delta shows zero after new best lap (since v7.4.1)
- Fixed: GoPro import may link the video file to a wrong time
- Fixed: GoPro import problem with accelerometer and gyroscope data


  • Some new bugs were reported and fixed for v7.4.1. Hopefully this one is production quality :smile:

    Testing an external display for the new Monitor API to fetch data live from Racechrono over BLE. Code for ESP32 and NRF52 is working (I've fetched GPS data using the example code from aol 👍)

    MagnusThome it's just amazing how many possibilities there are! it would be nice to do a simple setup of the output results and use a simple Nextion Display!
  • @GooGT Sorry, don't have a Nextion display to do it on :smile:
