After using the esp_restart() function that restarts both cores, specifically in my project, UART2 stops working, causing the GSM module connected to this UART not to work properly.

I have seen several github reports about this problem. How can I completely restart all UART channels? Or even make a more complete software restart...

Anyone help? I need know a solution about this uart2 + sw rst bug...

Your idf version has uart reset fix?

This update is from November and I'm using the latest version (3.0-rc1 December). So I think so, have the correction.

Why does this still occur? How to fix? I need sw rst running

I had a similar problem (https://esp32.com/viewtopic.php?f=2&t=4725) which was resolved with this commit https://github.com/espressif/esp-idf/co ... fb61431339.

I'm testing this "new update" and it's still not working. I do not know if these changes were made to the Arduino Core UART (I'm using UART and WiFi from Arduino Core), however, it does not work and UART2 is still bugged.

Maybe I will test the IDF UART in the future if this update did not affect the Ard-Core UART, so I will be forced to test it.

Any ideas for a solution to this if the update affected the Ard-Core UART?

Yes you should always specify which code base

When do you think this correction will occur in Ard-Core? If it takes too long, I'll use the IDF-UART.
