BME680 BSEC for Python

[level42]

Hello, there are clear instructions on how to compile a Python stack here, but the script is made for an old BSEC release 1.4.6.0. Generic Release. Is there anybody out of there who can drop me a copy of that specific release or with the skills to address the script toward the latest release BSEC 1.4.8.0 ?

Thank you in advance

Can you share your Python script here? 

Currently, we didn't make any formal release package for Phython version of BSEC lib.

So i want to take a look for the current one and check if it is able to be used for latest version.

Hello

A third-party python interface/wrapper is available here: https://github.com/rstoermer/bsec_bme680_python

and basically  the new BSEC release is compatible with the older one, by "compatible"  I mean the APIs provided by BSEC such as: bsec_init(), bsec_do_steps() etc remain the same,  so you could pretty much replace the files in: https://github.com/rstoermer/bsec_bme680_python/tree/master/src/BSEC_1.4.6.0_Generic_Release_2018042... with latest BSEC release, and with minor changes (if any) expect the python interface to work. In theory, no work on the python side is needed.
