Unfortunatly there is not a general purpose LoRa support forum that I know of. Semtech run a ‘Knowledge base’ but you can wait many weeks for a reply in there.
So there is a tendancy for general LoRa queries to be raised in this forum, just because most often if you do an Internet search this forum crops up as being somewhere that LoRa is discussed.
Point to Point LoRa is very different in application to The Things Network (TTN) and the software libraries are completly different too.
It would be quite easy for this TTN forum to become the place on the Internet for ‘LoRa’ support and that would overun the intended purpose of this forum, which is to support TTN.
