Here is my setup. I have Thonny running the little test script you provide on the pico at the bottom right. I have GP8 and GP9 connected on the bottom left meshtastic unit to gp9 and gp8 on the unit on the right. I’m using the unit on the upper right to monitor transmissions. I used the web interface to configure the meshtastic unit to use the serial interface. I can send messages using the web interface but it does not transmit anything coming in on the serial port .
