Chinese module, I2C error about ccs811

Hmm
You tried a lot already.

The Arduino library for ESP32 version 1.0.0 has an i2c bug: it does not support repeated start conditions. This seems to be fixed in release 1.0.1. Which one are you using?

Thank you for your answer

I was on 1.0.0 ...
I just upgraded to 1.0.2, but still the same :/

Wait!
I tried to test again all combinations, and this one seems working:

CCS811 ccs811(-1);
Wire.begin(21,22); 
//ccs811.set_i2cdelay(50);

I do some tests more.
Edit: wow, now all combinations are working... don't understand!

I get this:

setup: Starting CCS811 basic demo
setup: ccs811 lib  version: 10
setup: hardware    version: 12
setup: bootloader  version: 1000
setup: application version: 1100

So I should upgrade my CSS811 firmware

Starting CCS811 flasher
setup: library     version: 10
setup: hardware    version: 12
setup: bootloader  version: 1000
setup: application version: 2000
init: already has 2.0.0

Done!
Thank you much for your library, repository and help :)
