I see there is a way to communicate directly with the LoraBee using a proxy script running on the Autonomo LoraBee RN2483 module but can this be used to update firmware?
It should be possible to run the update using a pass through sketch where all the data from the SerialUSB or Serial is sent to Serial1 and also in reverse.
If the update process requires and specific interaction with any of the other IO pins (besides the TX/RX), that might be a bit more difficult.
@philroche Did u get this to work? Because i have the same setup and also need to update the RN2483.
Please let me know, and if u can please post the sketch.
