    BSEC2 library not compiling for esp32

    BSEC2 library not compiling for esp32

    Hello,

    I am trying to use the BME688 sensors using Sparkfun breakout board and BSEC2 library on Arduino IDE 1.8.19 and esp32 pico d4 dev kit with I2C protocol. I followed the instructions on GitHub for the BSEC2 library. I can get the generic_examples > basic.ino to work on MKR Wifi 1010 board but on the esp32 pico d4 dev kit I get the following error when compiling: 

    undefined reference to `bsec_sensor_control'
    collect2: error: ld returned 1 exit status
    exit status 1

    May I please ask for help on this?

    Thank you,

    Christoforos

    Hi Christoforos,

    Which link you got BSEC2 library and BME688 sensor API when you compiled them on ESP32?

    So, I found that I don't actually need the BSEC2 library since I only need raw data. The related post is this "BME688 sensor not sensing". Hence, I will be using the BME68x library only.

    Thanks a lot!
