BSEC 1.4.9.2 support

[pficheux]

The "BSEC_1.4.8.0_Generic_Release" version defined in "make.config" is no longer available.

Is there any support for the current version (1.4.9.2) available from https://www.bosch-sensortec.com/software-tools/software/bsec ?

Thx by advance

Yeah, Bosch officially only supplies the most recent version. Unfortunately the new versions are no longer C only, but C++ and I am (currently) unwilling to change things over to C++ in my free time. PRs welcome though. If you are lucky you might find an untempered version of BSEC =< 1.4.8.0 from somewhere else (I’ve seen downloads floating around on their forums), because Bosch’s license forbids individuals to distribute them. I might put some hashes of the versions I still have in the Readme though so you can at least check if they have been tempered with or not.

Thanks for the quick answer ! I don't like Bosch policy regarding software. I bought another device from Kitronik based on the same sensor but using a Pi Pico. The software is written in MicroPython, open source, well documented :-) https://kitronik.co.uk/blogs/resources/pico-smart-air-quality-board-using-the-bme688-sensor

But that doesn't use the BSEC, just normal sensor control, you can do that with a Pi and Python easily, e.g. with Pimoroni interpretation. https://github.com/pimoroni/bme680-python

Don't these use BSEC2 now if you go the BSEC route. Not looked for a while.

I just added the checksums of prior versions.

Hi! you can upload the BSEC_1.4.8.0_Generic_Release.zip?

Unfortunately no. Bosch’s license forbids individuals to distribute them.

I just downloaded the 1.4.8 version of the library from the Bosch web site:

hbarta@olive:~$ ls -lrt ~/Downloads/bsec_1*
-rw-r--r-- 1 hbarta hbarta 5618846 Aug 22 13:52 /home/hbarta/Downloads/bsec_1-4-8-0_generic_release_updated_v3.zip
hbarta@olive:~$ 

Edit: Further I can confirm that the new library builds if the first line in make.config is tweaked to point to the right directory:

BSEC_DIR='./src/BSEC_1.4.8.0_Generic_Release_updated_v3'

Here's the download for people looking for 1.4.8.0: https://www.bosch-sensortec.com/software-tools/software/previous-bsec-software-versions/

Works as of Aug 24, 2023

Hi, why can't I compile? I have BSEC version 1.4.8.0 but it gives below error, any idea why? I'm compiling this on RPI 4, 64bit os.
