How to communicate with the ESP32 module?

[AlexeyPechnikov]

I'm trying this code for the serial communication but it doesn't work:

import machine
uart = machine.UART(1,115200, rx=machine.Pin(9), tx=machine.Pin(8))
print('UART Serial', uart)

uart.write('AT\r\n')
print (uart.readline())

The code expected to print "OK" but it doesn't.

T-display is without ESP32C3. Please confirm your board is T-PICOC3 or T-DISPLAY-RP2040

Sure, I mean the board with wifi module (esp32) plus display (st7789). Actually, I’ve connected to the UART interface and can use AT commands but it’d be better to provide ready to use MicroPython library to it, right? Also, how to use the internal Bluetooth module from MicroPython programmed Pico?

I have provided the micropython firmware in the routine, the address is here
