I've found the issue. I'm calling UART initialization two times...
thanks for your support!

All right. Could you provide some example? If I remap using uart_set_pin function

ESP_ERROR_CHECK(uart_set_pin(UART_NUM_1, GPIO_NUM_4, GPIO_NUM_2, UART_PIN_NO_CHANGE, UART_PIN_NO_CHANGE));

I get the same error: UART driver already installed

I want to use UART1 over GPIO9 and GPIO10 in a ESP32-MINI-1-N4 for a basic serial communication. Everything goes well about UART1 configuration, compilation and device flashing. When I run the idf monitor it says that UART1 is already used and the device resets continually. What's going on? Is the U...
