    BME688 BSEC update problem

    BME688 BSEC update problem

    hello

    i have developed a custom board using ATSAMD21G18A as MCU  and connected to a BME688 sensor.

    i used the BSEC example provided by bosh for arduino and modified it to meet our MCU ( changes in SPI functions and delay ).

    the problem is that when starting the application the bsecCallback function is called only once and after that no call is performed.

    i used the cortexM0+ as library.

    is there any modification to do to the Arduino example to avoid this problem ?

    thanks.

    Hello Zaki13,

    Did you refer and run BSEC Arduino example on github?
    https://github.com/BoschSensortec/BSEC-Arduino-library/tree/master/examples

    hello

    thanks for your message.

    i fixed the problem, it was related to SPI timming.

    now the BSEC callback is called during 53 seconds and then stops updating for about 1min40s , and starts again for 53 seconds.

    is there any explation on this behaviour.

    Regards.

    Hi again

    du to availlability of Microcontrollers this days, i want to use this one  : PIC32MM0128GPM036.

    is this component compatible with one of the BSEC libraries provided.

    Regards.
