    BME688 Developer Kit Firmware Upgrade issues

    Hello,

    i had issues using the app with the BME688 Development Kit. After searching i found a solution in this post. I had the new app (1.3.3) and bme ai-studio (1.6.0) versions and noticed that the firmware on the dev kit was still an older version. I upgraded the firmware with the Flash.bat found in the BME688_x8Board_v1.5.0 folder. The upgrade was sucessfull, but now the dev kit is starting to blink red and is unable to write any data. The dataBlock only contains the following line: [null,null,2200,1644423036,null,null,null,null,null,null,0,-10]. I've tried reflashing several times, aswell as using different bme config files. The result stays the same. I attached the used config file as well as the corresponding bmerawdata file. Am I doing something wrong on the firmware upgrade or is there another solution to this problem?

    Thanks in advance,

    FrankW

    Hello BSTRobin,

    i followed these steps the first time around. I now did it again. I first flashed the Feather Board with a dummy programm. After that i assembled the the dev kit by inserting the sd card with the bmeconfig file and the battery cell. I put both boards together and ran the flash.bat. The result is still the same. I attached the bmeconfig file that i used during the flashing process and the bmerawdata file that the dev kit produced after the flashing.

    Are there any other solutions you can think of?

    Regards,
