I2C Timeout isue ESP32

1

Hi
2 Month before I had a running code.
I find out that there is a problem with timeout threshold in latest esp32 version

I want to go back to an older platform (5.2) but than I get compiler Problems.
The Code that works before don’t compile.

So my question. How to get back to the Versions of all 2 Month before

regards

Which Espressif32 Platform versions do you have installed right now?

If you use platform = espressif32 without fixing it to a specific platform version, the version with the highest version number will be picked by platformio.

I am a bit confused about your Arduino version “2.3.5”. There never was such an Espressif Arduino version. The latest 2.x version was 2.0.17 (platform-espressif32 6.8.0 - 6.10.0) - See this list

There also was no Espressif Arduino version which based on ESP-IDF 5.2 (see the list above).

Did you install pioarduino to get the latest Espressif Arduino core (3.x) ?
If so, this version will be picked up by platformio as it has the highest version number. The change from 2.x to 3.x comes with a lot of API changes which breaks existing code - See Migration from 2.x to 3.0 - - — Arduino ESP32 latest documentation

If you want to go back to a specific version, simply change the platform setting in your platformio.ini

Example, to get Espressif Arduino 2.0.9 based on ESP-IDF 4.4.4:
platform = espressif32 @ 6.3.2

I’m having the same problem on my arduino platform, going back versions didn’t help me. Let me know if you find a solution!

So you are using the exact same (but still unknown) espressif32 platform version? And you also have tried a newer Espressif Arduino 3.x by using pioarduino? :wink:

The problem was fixed in latest version when use

platform = espressif32

thanks for Your try to help, sorry for late responce

The situation is still unclear as there is no version specified.

platform = espressif32 in your platformio.ini will either

  • install the latest available official espressif32 platform by PlatformIO if no espressif32 platform is installed to your system
  • or use the espressif32 platform on your system wich has the highest version number

You have to check which versions are installed on your system or have a look at the output during a build.

If you want to stick your project to a specific version you have to specify the version of the platform to be used. Example: official espressif32 platform 6.11.0 by PlatformIO:

platform = espressif32 @ 6.11.0

The project is using Espressif Aruduino version 2.0.17.

What’s the Espressif Arduino Version you’re using in your project?
