Python Client Libraries

We provide two python libraries that facilitate the development and speed up the integration of Node Sensor into your IoT application.

LoRaWan payload encoding / decoding library

This library (sensor_node.py), takes care of the encoding & decoding of the sensor Node’s LoRaWan Uplink and Downlink payloads. The module can be integrated to an existing project; it also contains a demonstration code to illustrate how to use the library.

Nodes Manager

The node manager (nodes_manager.py), connects to the MQTT broker of your LoRaWan gateway and manage all detected sensor nodes:
  • Sends configuration to new nodes.
  • Received and decode incoming sensor readings uplink.
  • Publish decoded sensor readings values to MQTT server for easy integration.
Before using the nodes manager, you need to fill up the configuration variables in config.py with the details of your MQTT server and LoRaWan gateway.
