This is an updated continuation from this project.
The Things Network is now on version 3, which requires LoraWAN 1.0+, which does not allow single channel gateways.
Although Paul and I still have TNN accounts, there are no entries for the gateways we had setup. We set up a
makeitzone-ca organization; we believe we had created a
makeitzone organization, but suspect it’s no longer accessible due to us not logging in for a long time and the TNN upgrade to version 3.
The AdaFruit PiHat with RFM95W no longer work with the Things Network using the example CircuitPython code. There does not seem to be a LoraWAN node stack for the Raspberry Pi.
LMIC-Node looks to be the easiest way to create a working node.
Cayenne Low Power Payload is the suggested data format to be used in data packets.
