BME688 and BSEC2 x8 board Arduino example reading multiple sensor in parallel

[ECall]

Hi,

I am currently using the BME688 x8 evaluation board alongside the Feather adafruit ESP32 board. I use the BSEC2 library.

After setting up the multiple necessary librairies, the "basic.ino" arduino example with x8 board works well with one sensor : I get the expected readouts every 3 seconds, matching the sample rate configured.

But if i try to get readouts from another sensor on the board, the configuration works fine, but one sensor is giving me a : 

BSEC warning code : 100

I know that reading data from multiple sensors is possible with this board, as the arduino example used alongside BME AI studio works fine. But the level of abstraction used in this example is too much for my need.

Is it possible to have a heads up on how to read data from multiple sensors in this simple example ?

Best regards,

ECall

Hi Ecall, 

Basic.ino can only read one sensor data each time. 

If you want to change the target sensor, you need to chage below definition in basic.ino. 

#define SENS_NUM 7

The value should be from 0 to 7. 

Please let me know if you have further quesitons. 

Thank you.
