Compile error ESP32+BME688 dev kit

[ArunSharma]

I am using BSEC_2.0.6.1_Generic_Release_04302021. 

I dont see a file BSEC2 .cpp file here in the dwonloaded package. I see only BSEC.cpp its version 1.5.0 dated 23 April 2021. 

I downloaded the package from : https://www.bosch-sensortec.com/software-tools/software/bme688-software/

I am using the platform text that you provided in the previous messages. However, I am attaching the platform.txt file I got as part of the 1.0.6 library when I installed it. 

[Minhwan]

Please use this one in 

C:\Users\omi1syv\AppData\Local\Arduino15\packages\esp32\hardware\esp32\1.0.6

I'm using same one. 

Please let me know and post your error if you have. 

Thanks,

Hi 

I tried the platform.txt file you shared now and still see same errors.  I am running on Arduino 1.8.13 IDE. Any impact and should I upgrade it?

I tested 1.8.15, but I think 1.8.13 should be okay. It's more like library registration problem. 

Please follow my steps. 

1) Make zip file bsec2.zip as below folder

\bsec_2-0-6-1_generic_release_04302021\BSEC_2.0.6.1_Generic_Release_04302021\examples\bsec2

2) Sketch -> Include Library -> Add .Zip library (Choose the zip file) 

3) Build example code 

\bsec2\examples\basic_config_state\basic_config_state.ino

Thank you.
