BME68x reporting BME68X_E_COM_FAIL

[Minhwan]

Hello Wenator, 

Are you using GPIOs as I2C? 

Arduino has assigned I2C pis and depends on I2C there is pull up resistor or not. 

I strongly recommend to use assigned I2C pins. 

Thanks,

Hi,

I tried the assigned I2C pins, but still receiving bme68x error code -2.

Thanks

Please check our bsec 2 library example code. 

Our example code is based on Arduino. -2 means communication error, so it means that there is hardware or software issue for communication. 

Thank you.
