If you are using exactly same code, you should get within 20mins.
Could you share your code?
Here is my main.c and the bsec_integration code where I included CO2e and bVOC in bme680_bsec_update_subscription(). I also changed the value of NUM_USED_OUTPUTS and BSEC_MAX_PHYSICAL_SENSOR from 8 to 10 in bsec_datatypes.h.
Please note that for configuration I created a library (bsec_config) where I used the bsec_serialized_configurations_iaq file from generic_33v_3s_28d.
Regarding generic_33v_3s_28d files, could you explain what XML and CSV files stand for? I’m not using any of them.
Also I’m using the lite version of bsec library. Is there any chance this problem is related to the lite version?
