    BME680 with BSEC produces on 0.0s, even after 20 min

    Dear all,

    I have integrated the "BSEC_1.4.8.0_Generic_Release" into my application to operate the BME680 based on "BME680 shuttle board" over I2C (SD0 set to GROUND).

    The result is: the callback function of "output_ready" produces only 0.0s, even after 10 mins of operation:

    730703 DEBUG: T: 0.00 degC, P: 0.00 hPa, H 0.00 rH, G: 0.00 ohms
    733703 DEBUG: T: 0.00 degC, P: 0.00 hPa, H 0.00 rH, G: 0.00 ohms
    736703 DEBUG: T: 0.00 degC, P: 0.00 hPa, H 0.00 rH, G: 0.00 ohms
    739703 DEBUG: T: 0.00 degC, P: 0.00 hPa, H 0.00 rH, G: 0.00 ohms
    742703 DEBUG: T: 0.00 degC, P: 0.00 hPa, H 0.00 rH, G: 0.00 ohms


    The setup is:
    STM32L462RE
    toolchain: SysGcc, GCC 7.2.0, GDB 8.0.1 revision 3
    software: BSEC_1.4.8.0_Generic_Release

    integrated lib: BSEC_1.4.8.0_Generic_Release/algo/normal_version/bin/gcc/Cortex_M4F/libalgobsec.a

    integrated software samples (as is, unchanged!)

    BSEC_1.4.8.0_Generic_Release/examples/bsec_iot_example.c
    BSEC_1.4.8.0_Generic_Release/examples/bsec_iot_example/bme680.c
    BSEC_1.4.8.0_Generic_Release/examples/bsec_iot_example/bsec_integration.c

    callback functions I have populated:

    bus_read, bus_write, sleep (in ms), get_timestamp_us (in us), output_ready

     

    callback functions I have left empty:

    state_load, state_save.

     

    Any help to resolve this issue is much appreciated.

    Thanks

    Hello mhammer3,

    When you run BME680 example, could you get chip ID in bme680_init()?

    Thanks,

    the chip_id after calling bme680_init is 0x61.

    Please note: I am running the "bsec_iot_example.c" example

    Hello ,

    After your code called bsec_iot_init(), all return values were correct in bsec_iot_init()?
