I want to passthrough data from UART to BLE as the BLE notify enabled.Then I create a task to deal with it,at the first time, all is normal,but after I delete the task and create it again,the UART data are all "A5",and the length is 255,even I didn't sent any data to UART...

I'm having an ESP32 logging via uart at 115200 for a while, then while working normally I got what is seen on the image. Could this be related to a bad hardware unit or may be a bad electrical design of the board? Anybody seen this before? I'm using ESP-IDF 5 an ESP-PROG ...

I have an ESP32-S2FH4 chip, USB-UART is connected to it via UART0. When trying to flash the chip, the error "A fatal error occurred: Failed to connect to ESP32-S2: No serial data received" is displayed. At the same time, the device enters the bootloader correctly, debug messages ...
