Pico +Sim800

[Izqbr]

I used the sim800 driver https://github.com/pythings/Drivers/blob/master/SIM800L.py. I have set up self.uart = UART(0, 9600, timeout=1000, rx=self.MODEM_TX_PIN, tx=self.MODEM_RX_PIN) MODEM_TX_PIN = 0, MODEM_RX_PIN = 1 and I get an error: ValueError: bad TX pin. I am transmitting 0 but have to set up Pin(0).
How to configure it correctly?

Pin 0 of the RP2 is UART0/tx, to be connected to the modem's rx pin, Pin 1 is UART0/rx, to be connected to the Modem's tx pin. So you have to swap the connections.

Thank you. I fixed it and now there is no problem!
