BME688 Developer Kit Firmware Upgrade issues

[FrankW]

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 FrankW,

Could you confirm you follow the following step and upgrade software successfully?

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,

FrankW
