I'm developing a custom project for thingy53.
I'm trying to use the bsec2 library to use the bme688 in Thingy53, but there's no reference example anywhere.
With the library provided by bosch, the libalgobsec.a and bsec_interface.h and bsec_datatypes.h files, I succeed to compile together.
But I don't know how to program them including config files.
I find the example with bme680 which is integrated in Thingy91, the asset tracker.
However, that was meaningless because the bsec library version is different (bme680 -> bsec v1.4x / bme688 -> bsec v2.0x) and because of different version, the structure of library is also different.
I think the Thingy53's edge-impulse example uses bme688. But also, unlike Thiny52, Thingy53's source code is not distributed.
So, is there example that adopts bme688's bsec lib. v2.0x for the custom project?
If not, How could I integrate bsec v2.0x library to my custom project?
Here's my CMakeList.txt. I built my project based on Nordic_LBS example from NCS v2.0.0 (zephyr) with Thingy53.
