Azure IoT Edge LoRaWAN Watteco Sensors Support

Description

This repository stores the code for executing an Azure IoT Edge LoRaWAN Decoder module for watteco Sensors.

Batch Uncompress

By default this module will uncompress batch data coming from sensors with default configuration once they are provisioned on the IoT Platform. The uncompress function is made by the br_uncompress_py module that can be downloaded at : http://support.nke-watteco.com/downloads/

Batch V.S Standard

NKE Sensors can send multiple frame types. Some of them can send batch frames (which can be disabled) rather than other can only send unitary frames.

To distinguish which kind of frame is present, the decoding function will be aware of the first bit on the first Byte of the payload.

• 0 : Batch
• 1 : Standard

Current Sensors Available

Current Version of NKE uncompress module used is 1.0.5.

Deploy

You can add this module to you IoT Edge Deployment by adding this module definition:

{
...
    "WattecoDecoder": {
        "settings": {
            "image": "kbeaugrand/az-iotedge-watteco-decoder-module:latest",
            "createOptions": ""
        },
        "type": "docker",
        "version": "1.0",
        "status": "running",
        "restartPolicy": "always"
    }
...
}

Tests

You can use this project to launch the decoder and test manually test it.
