By the way I’m using @gonzalocasas fantastic setup on my RisingHF gateway. Just had to change the reset pin number in start.sh to match my setup.
Probably the best to use since it has all the right versions of the packet forwarder and is very well tested with TTN. It is EU focused (as far as I know) so you’ll need to change the configuration to use the US frequency plan and correct TTN server.
