Reply to PyGate code for GPy with LTE backhaul sending decoded values direct to azure iot hub on Sat, 07 Nov 2020 14:56:54 GMT

Hi i want to remove the usage of a lorawanserver step and send lorawan sensordata direct from pygate to azure iot hub using gpy/ LTE sim. Is it possible to omit the packetforwarder and send data in another fashion?

We need a small setup from a solarpowered pygate which shall be placed in the outback..

Any ideas or help much appriciated

All the best
/ Johan

Hi,
In theory this should be possible (note that I have no prior experience in azure iot)
The Pygate basically forwards a JSON containing the data to the LoraWAN server, you can change the server to redirect to an azure iot hub, but I imagine the azure iot hub cannot work directly with the packets forwarded, meaning you will have to write some adaptation in C and compile custom firmware. I can link you to the file that will need changing:
https://github.com/pycom/pycom-micropython-sigfox/blob/Dev/esp32/pygate/lora_pkt_fwd/lora_pkt_fwd.c#L1491
this test case falls through for Lora packets with a correct CRC, then the JSON is asembled based on the RF receive data. I think you will have to make some changes there in order to get the thing working for azure Iot.
