    BSEC Error code -2 on ESP32 arduino core

    Executed all the steps from Integration Guidelines for Arduino platforms.pdf. the library seems to be properly installed, the examples can be compiled without warnings and downloladed to the target platform. However, all the examples in form BSEC folder display the following error message after loading:

    BSEC Error code -2

    Any ideas?

    What is strange that example from Bme680_Data folder basic_data_logging.ino works fine

    Hi there, 

     

    i am having the same problem, assuming I am using the latest code from the git, the patch should not be a solution.

     

    I am using the esp32 devboard v1, I used the esp8266 also, both returning error code -2. I am using the latest version of Arduino IDE.

     

    I tested my sensor with a basic sketch from adafruit and I was able to get the raw readings.

     

    I am using this sensor:

    Thanks for your help.

    I managed to solve the problem, for anyone trying to do the same here is the solution:

    I used an I2C scanner and foud the device adres, in case it was :0x77

    so I changed this line:

    iaqSensor.begin(0x77, Wire);

     

    Regards,

    AY
