BME680+ESP32 - Warning code: 2

[pattagghiu]

Hello,

i have a bme680 running on a esp32

the ESP also drives some other sensors and devices. The BME works in ULP so the reading is triggered every 5 minutes.

i really don't know what happened, but eventually i started getting warning: 2 from the sensor, which should need "no new data"

now and then, it starts working again but after a random time (up to hours) it goes back to the warning.

the timing between measurements can't be guaranteed as of ESP32 working mode.

I have to admit i am quite close to abandon the bsec library 🙂

any idea?

thanks

Another user kindly reported recently having solved the same warning code for the ESP32 by switching to a different power source, maybe you could investigate that. Timings are always important, analog/logic traces and code could potentially also shed some lights.
