I’ve been plagued with this problem for about a week, during which there were a few board and library updates. I’m fairly sure the sketch and hardware worked fine two weeks ago. Wondering if anyone else has noticed any issues recently with I2C connections. I’ll try and narrow it down too.
Well after trying to isolate some of the few lines of code directly related to establishing a connection. I’ve not found anything conclusive. Instead I might try a workaround and use I2C on a separate microcontroller
I’ve been advised of a possibility of creating another I2C bus … don’t know if it will help.

Anyone else tried this ?
