    BME680 resets to iaqAccuracy=0 if not refreshed within 4.25 seconds

    BME680 resets to iaqAccuracy=0 if not refreshed within 4.25 seconds

    Hi,

    i use BME680 on ESP32 with basic_config_state code.
    BME680 needs 307 secounds to go iaqAccuracy=3.
    iaqSensor.run() has to be called at least every 2.770 - 4.250 secounds before it drops to iaqAccuracy=0.

    Works nice - until i want to send data.
    My GSM Module needs 3 times around 10 secounds where i can't call iaqSensor.run().

    After sending Data the BME680  dropps to iaqAccuracy=0 for 307 secounds.

    How to solve this?
    I tryed using timer, but iaqSensor.run() needs 0,247 secounds - that messed up my GSM send.
    Can i tell the BME680 to do his thing and i fetch data later?

    Regards,
    Frank

    Solved the issue by running BME680 (and I2C communication) on core 0 only.
    GSM, Wifi, time schedule and measurement of radon runs on core 1.

    Hello internovum,

    Good!

    If the development environment supports multitasking, use multitasking to deal with different things.
