Sleep mode about ccs811

[maarten-pennings]

Hi, I'm guessing you try to run this on ESP32.
The esp_deep_sleep_start() puts the ESP32 in the deep sleep mode.

I'm not yet very familiar with the ESP32, and not at all with deep sleep, but when reading randomnerdtutorials, I found this quote

In the setup() is where you should put your code.
In deep sleep, the sketch never reaches the loop() statement.
So, you need to write all the sketch in the setup().

This makes sense to me, a deep sleep ends with a sort of "reset".

So, the bug seems to be your program and not in the CCS811 lib: when using deep sleep, all code needs to be in setup and needs to be prepared for the continues "resets".

Thank you very much, it seems that this has solved my problem.

Glad it works.
If you're happy too, please close the issue.
