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

[internovum]

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!
