BME688 connection to Android App

[AMELIE]

Hello,

Thanks for the instructions to connect the BME688 Dev kit to the app, it worked well. However, when the bluetooth is activated, the data is not saved to the SDcard correctly. The data is saved randomly and splited into small files of 7 ko which cannot be used by the BME AI Studio software. Could you help me solve this problem?

Thank you

Hello Amelie, 

When you run the android application, that means you already have your own data. 

Therefore, if you want to gather data, please use bme688 dev kit without app. 

Thanks,

Hi there,

I hope I'm not to late.
I can't get the app to work as well with the same error message.

Actually I alread tried reflashing the ESP32 but this didn't help.
The only conf+bmeconf which work are the ones provided with the BME688_x8Board_v1.5.0 software folder.

But of course I'd like to train and use my own data and conf and not only detect H2.

Is the older Version of AI Studio available somewhere? 
Version 1.5.5 seems to work just finde with 1.5.0 board software.

Best regards
Benjamin

Hello,

I just downloaded latest softare from bosch.

x8Board record raw data fine, i also can connect to android app but on the app "Testing" is greyed out and i cant try out how trained algorithm works but android app shows some real time data being scanned.

I suppose it is due to that i should be flashing BME688_x8Board_v1.5.0 on x8Board and not latest BME688_x8Board_v1.5.5 because android app about says firmware 1.5.5.

Could you please kindly share BME688_x8Board_v1.5.0.zip somewhere ?

Thanks

Hi kareig, 

Yes, we recommend to keep using latest version and it's same for AI studio feature as well. 

Here is the v1.5.0. 

But latest version is as below for your information. 

BME688 dev kit - v1.5.5
