      In the end, keeping the same wiring, I formatted the ESP32 and reinstalled the firmware and it worked fine.

      Thank you for responding so quickly and for your work. It’s a very good job, congratulations

        Hi Renzo,

        I have an E220-900T220 with ESP32-WROOM-32.

        I had to modify line 330 module lora_E220 because I was getting an error from Invalid model

        class LoRaE220:
        # now the constructor that receive directly the UART object
        def __init__(self, model, uart, aux_pin=None, m0_pin=None, m1_pin=None,
        uart_baudrate=SerialUARTBaudRate.BPS_RATE_9600):
        self.uart = uart
        self.model = model

        pattern = ‘^(400|433|868|900|915|170)(T|R|S|M)(22|27|30)(S|D|C)?..?(\\d)?$’

        Now I get the data size error, see image
