This project is now live on github.com, sample Arduino with Dragino LoRa Shield for Arduino, MakerFabs Maduino, Dragino LoRa Mini Dev, M2M Low power Node and Netduino with Elecrow LoRa RFM95 Shield clients uploaded in the next couple of days.

The bare minimum configuration is

{
  "AzureIoTHubDeviceConnectionString": "HostName=qwertyuiop.azure-devices.net;DeviceId=LoRaGateway;SharedAccessKey=1234567890qwertyuiop987654321qwertyuiop1234g=",
  "AzureIoTHubTransportType": "Amqp",
  "SensorIDIsDeviceIDSensorID": true,
  "Address": "LoRaIoT1",
  "Frequency": 915000000.0
}

So far battery life and wireless communications range for the Arduino clients is looking pretty good. CRC presence checking and validation is turned so have a look at one of the sample clients.

It took a bit longer than expected as upgrading to the latest version (v1.18.0 as at 12 Sep 2018) of Microsoft.Azure.Devices.Client (from 1.6.3) broke my field gateway with timeouts and exceptions.

I’ll be doing some more testing over the next couple of weeks so it is a work in progress.
