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

[mhammer3]

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()?

[mhammer3]

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()?
