Using bsec2 on esp32 without bme68x

[IbtissamELB]

Hello everyone,

I am dealing with an issue integrating BSEC2 with the BME688.

I am trying to use the signal processing capabilities of BSEC2 in scan mode for classification, but all the outputs of `bsec_do_steps` are 0.

Please note that I am using the library separately from the sensor. The sensor has been configured statically, and I am trying to process its outputs separately on another ESP32. Therefore, I am directly using functions from `interface.h` and have eliminated the use of `bsec_control`, as the data is transmitted from another microcontroller (nRF) responsible for data logging.

Is this approach even possible, or is there an issue with my software?

Hi IbtissamELB,

Thank for your inquiry.
The BSEC v2.6 software package on the official website includes an example of gas scanning. You need to replace your configuration file that supports gas scanning with this example and run it.
