ESP32 Forum

Hello,

I have an CP2102 connected to the TX and RX of the ESP32. Whilst deep sleeping I turn the CP2102 off (No 5V, internal 3.3V regulator thus dead too). The ESP32 still "feeds" the CP2102 through the TX Line of the ESP32. How can I turn off the Debugging UART Peripherie?

I already tried to uart_driver_delete on all 3 UART peripheries.

You should be able to use gpio_output_disable on the GPIO to make it a GPIO input.

Works, thanks!

Is ur problem solved??
I also facing same problem with esp32......
