    BSEC2 v1.5.2400 RAM overflowed

    BSEC2 v1.5.2400 RAM overflowed

    The example "bme68x_demo_sample" does not compile.

    Out of RAM: "dram0_0_seg" overflowed by 9256 bytes.

    Each instance is allocated in memory: BSEC_INSTANCE_SIZE 3272

    There are two conflicting defines:

    NUM_OF_SENS 4

    NUM_BME68X_UNITS 8

    Where to specify the number of sensors, and where is multi instance? How to run this version at least on a standard board with 8 sensors? The new version is very demanding on memory and cannot be applied to a large number of sensors > 8.

    After uploading the demo from the 1.4 BSEC2 library, the (latest) Android app now complains about missing bsec config, but it's on the sd card. 

    This thread suggests matching the right version of AI studio. I'm currently on the latest, but not sure how to get older versions from Bosch. 

    Do you happen to have the matching versions and wouldn't mind uploading here? 

    When exporting the config, you can select the version of the BSEC library:

    I will attach demo configs for version 2200.

    Hi all,

    bme68x_demo_sample is the code implement of bme68x_demo_sample.ino.bin under folder "BME688_x8Board_v1.5.0\BME688_x8Board_v1.5.0".
    If you would like to run BSEC and get IAQ, CO2, estimate output, you should run the example code generic_examples https://github.com/boschsensortec/Bosch-BSEC2-Library/tree/master/examples/generic_examples
