Hi Leigh

I have previously deleted the MPU6886 so that there are no problems but I did not posted it,sorry.

I changed the code, Insert the {0} and there is no more error message. Very good!
I2C hardware works now.

Unfortunately I still read always the same values from the BME688 for humidity and temperature:

177.384328
33.551110

regards

Stefan

Hi Stefan,

Thanks for the update. Glad to hear the hardware I2C now works.
Your reading issue probably needs a look at the datasheet, which I can't help with just at the moment.

Ben,
Looks like ESP has some additional flags into the struct, so the CAL mod will fix this for newer installs, and be backwards compatible.
Cheers,
Leigh

Hi Ben

With the BME688 is still a small problem.
I can always read the exact same values..
Do I have to do something else than init and read values?
