    BME688 how to handle the event that BSEC bsec_do_steps return 5

    Hi,

    I'm using BSEC v2.4.0 with BME 688 on ARM m4 SoC. The system enables BME 688 scan mode with heat profile generated by AI studio. 

    It often sees bsec_do_steps() function return 5, i.e. Gas index not provided to bsec_do_steps() from log messages. Usually 1-2 times per hour.

    I don't see any problem from the input data of bsec_do_steps(). When this happens, I need to re-init the BSEC and sensors by calling bsec_iot_init(), otherwise it cannot retrun to normal state.

    The problem is when I reinitialzie the BSEC lib, the gas estimation will unstable for 1-2 min. The data shows peak. I can hide this for 2 min but seems not a good idea.

    Any suggestionon this issue? How to avoid bsec_do_steps() return error? Thank!
