i have a Raspberry Pi 4 where my arduino Software is installed.
Connecting some IOT device they are seen but my TTGO Boards the LoRa v1 or the T-Bean are not discoverd on the Ports.
i think there should be some driver installed but which one exactly?
have a nice day
Can you try connecting those boards to a computer to see if the computer sees them? So that we can check if it might be an issue related to the board or related to the Raspberry Pi.
