I also see strange behavior on the I2c bus. Serial debug is disabled, but I get the message - i2c.master: i2c transaction timeout detected. Full log:

1. The underlying ESP-IDF I2C driver has been changed
2. The information provided here is not enough to test/confirm any issue

Pleas provide full information and minimal compilable code example

I am also experiencing this issue. It occurred after Updating Arduino IDE to 2.3.5 from 2.3.4. The ESP IDF also updated at this time. I had never seen this error previously.

@lucasssvaz I noticed some changes attributed to you in the most recent update, any chances that is what’s causing the issue?

test(wokwi): Add I2C Master test and enable GPIO and PSRAM tests by @lucasssvaz in #10848

test(i2c): Add test to scan bus by @lucasssvaz in #11022

test(i2c): Do not use delta as Wokwi timing can be inconsistent by @lucasssvaz in #11080

@MarksWizard These PRs are related only to our I2C test in the CI. It does not affect how I2C works in any way.

After a bunch of testing, and even more hair pulling... I think it ended up being a wiring issue for me. I finally got code to run without the error, but it would still be nice if that message didn’t spam the serial like it does.

I see the same issue, but I can confirm that it does not seem to be a wiring issue.
Board: DoIT ESP32 DEVKIT V1
Arduino IDE 2.3.6
When the sketch is compiled with ESP32 library 3.2.0 it fails, (error messages as above) but after a downgrade to ESP32 ver 3.1.3 it works. No changes made to hardware, nor the sketch, nor other libraries.

Please list devices and libraries that you use with them, so that we can try to replicate any of the confirmed non-wiring issues.
