Config File missing #7

Closed mcalisterkm closed 3 years ago

mcalisterkm commented 3 years ago

The bsec config is missing from the source files, and as a result when I run any of the BSEC examples a missing file error is generated ,and the IAQ value remains unchanged at 25 with accuracy at 0.

I believe it is this line in bme68xmodule.c that is raising the error. const char *bsec_conf_path = "BSEC_2.0.6.1_Generic_Release_04302021/config/bsec_sel_iaq_33v_4d/2021_04_29_02_51_bsec_h2s_nonh2s_2_0_6_1 .config";

There is no such file in this repository. In the BSEC library from Bosch the configuration folder has a number of predefined configurations bsec_serialized_configurations_selectivity (.h and .c)

Perhaps the "bsec_sel_iaq_33v_4d" example "bsec_config_selectivity[2277]" array of ints could be added as a default configuration in bme68xmodule.c.

Did you download the licensed BSEC2.0 library from BOSCH and unzip to the bme68x-python-library-main folder?

Yes of course. I see that the issue is fixed in the 'BME 688 CheeseMeat' version. Also there is much better BSEC support.
