I have installed the Datalogger firmware using the USB-DFU bootloader as per as instruction: https://www.bosch-sensortec.com/media/boschsensortec/downloads/application_notes_1/bst-dhw-an012.pdf
After updating, the Status-LED of the Application Board 3.0 is blinking red. Besides that, I cannot connect the board with the Development Desktop 2.0 using USB. Which was possible before the update. Thanks!
Datalogger firmware is not supported by Development Desktop 2.0 GUI.
You'll need to flash the firmware "DevelopmentDesktop_2.0_Firmware_v0.9.bin" located in COINES\v2.6.0\firmware\app3.0 folder
1. Put Application Board 3.0 in bootloader mode (by powering ON the board with T2 button pressed, Blue LED show glow)
2. Run update_dd_fw.bat
