Cannot get downlink webhook from Cayenne to work

Did you read the previous responses on the other thread?

The JSON message shows a lot of cryptic stuff

Between your implied assumption that the Cayenne dashboard on/off would automagically send the right info to the LoRa-E5, given that nothing in the code processes incoming LPP, and the above statement, I think you’re redefining “travelling hopeful”. JSON is part of the LoRaWAN toolkit so it’s not a topic you can skip over. The same with Base64, the frm_payload you are sending is 010064FF which is NOT LPP format.

But whilst I have your attention, as a software guy, what the heck is an impedance matched pair - I can see it in KiCad but my USB doesn’t work - any tips?
