BME688 and BSEC2: bsec_sensor_control() not updating the operation mode

[mudit_sharma]

Hi,

I am using BME688 and BSEC2 with nrf52832 (nrf sdk 17.0.2). I am trying to implement the generic/basic example.

The function call to  "bsec_sensor_control()" in the run() function updates the next_call member of bsec_bme_settings_t struct but never updates the op_mode (Hence, the sensor is always in sleep mode). Subsequently, I'm unable to get any data output from the sensor. 

I have attached my code below. Please suggest how can I correct this error.

Thank you.

Hi mudit_sharma,

You could download BSEC 2.0.6.1 package from here: https://www.bosch-sensortec.com/software-tools/software/bme688-software/
Run "BSEC_2.0.6.1_Generic_Release_04302021\examples\bsec2\examples\basic_config_state" reference code, and see BSEC output values.

Hi,

I've tried the arduino examples and they work fine. I've converted the C++ code to C for my application and cant understand why bsec_sensor_control() wont update the operation mode but does update the 'next_call' member of the bsec_bme_settings_t struct. 

I've uploaded my code in my question. Can you kindly suggest what I might be doing wrong there? 

Thanks!

Hi mudit_sharma,

We are not sure whether your converted C code is correct. Can you send out the complete code for us to check?
