    Using the BSEC Library with a ESP32

    Hello everyone,

     

    I am currently trying to use the  BSEC Arduino Library with an ESP32-WROOM-32.

    I tried to follow the tutorial on the BSEC Arduino  Github Page but failed at point 3 (Modyfing the platform.txt file) as there was no

     

     

    -libalgobsec

     

     

    flag in my whole platform.txt.

    However, the output indicates that there is something wrong while linking the library, what could be the problem here?

    I made sure that the BSEC Library is imported as .ZIP file. Using the Adafruit Library for the BME680 works fine, its just that I want to utilize the IAQ calculations from the BSEC Library.

     

     

    Linking everything together...

    Re: Using the BSEC Library with a ESP32

    Hello Daniel, 

     

    You didn't follow one option, could you test with my platform.txt? 

    Thanks 🙂

    Re: Using the BSEC Library with a ESP32

    Hi, I am trying to interface BSEC2 with ESP32 feather which along with my BME688 Dev kit and I am facing the same issue. I am getting the error below. I have followed all the steps and finally replaced the platform text  with one given in this thread. I am still facing the same issue. I have checked that all these functions are defined in the library and there is no error with the included library file. Can you help? I am trying to run the basic_config_state.ino found in the example for BME688 dev kit.
