Hello, I followed your tutorial to use BSEC but I have this error at the setup.py install step :

I use the bsec2-4-0-0_generic_release_23012023.zip file.

Ah another new version of BSEC released in January 2023, the good news is that the API is still v4.4.7 but the release note says:

• Multi instance interface support – BSEC will support multiple sensors. Additional interface file ‘bsec_interface_multi.h’ added to support multi instance APIs. 
• Unified static library to support sensor variants, Configuration files offered separately for BME680 and BME688 sensors.  - Reduced library size by optimizing configuration and state properties for catering to multi instance support.

So potentially breaking changes.
Update tomorrow.

There were not too many changes (mainly paths) and you will find an updated version for BSEC 2.4.0.0
https://github.com/mcalisterkm/bme68x-python-library-bsec2.4.0.0

There is no support for multiple sensors and all your saved configs/state files need to be re-created.

Keith

Update: I have run sensors on two PI Zero for a 24 hour burn-in and all went well with state saved and subsequently loaded.
