You have been a big help!..Sometimes it just takes a second set of eyes…I am used to using dev boards which typically pass a UART over the debugger port as some sort of Virtual Comm…Now it is a matter of finding which UART port to connect up. Based on Seeed schematics of Lora-E5 development kit I presume the port is PB6/PB7.
I am only doing this to validate a Lora link with my spun PCBs to my gateway and to the TTN. To close the loop I really want to erase the AT firmware and place Lora-End_Node code on the board. I posted a link on this, see below. Would you have any insight here?
Lora-End-Node code instead of AT
Thanks again for the clarity above!! I will get a usb/uart and try this…
