ESP32 3.2.0 I2C fails

Other Hardware 3rd Party Boards

Board: DoIT ESP32 DevKit V1
Arduino IDE 2.3.6
Updated the ESP32 board library from 3.1.3 to 3.2.0

With this new version the serial monitor is continuously throwing error messages about the I2C.

Example from serial monitor:
E (596005) i2c.master: I2C transaction unexpected nack detected
E (596005) i2c.master: s_i2c_synchronous_transaction(924): I2C transaction failed
E (596011) i2c.master: i2c_master_transmit_receive(1220): I2C transaction failed
E (597046) i2c.master: I2C hardware NACK detected
E (597046) i2c.master: I2C transaction unexpected nack detected
E (597046) i2c.master: s_i2c_synchronous_transaction(924): I2C transaction failed
E (597052) i2c.master: i2c_master_transmit_receive(1220): I2C transaction failed
E (598033) i2c.master: I2C hardware NACK detected

After a downgrade to 3.1.3 again it works fine.

BTW: I think ESP32 version 3.2.0 - #4 by sonofcy might suffer from the same problem.

It looks like a bug that has been reported I hope.

The issue is reported here: I2C Fail 3.2.0 · Issue #11228 · espressif/arduino-esp32 · GitHub.

I suggest that you add your complete experience there including all steps to reproduce. Add a minimal example sketch that exhibits the behaviour. You need to be registered on github though.

The reported issue seems to have been a wiring issue, I guess that that is not the case if something works after being compiled with 3.1.3 and no longer works when compiled with 3.2.0 (without hardware changes).

Great! Thanks for the link!
I tried to look for similar issues on the espressif GitHub, apparently I didn't use the correct search phrases.
