iot-samples/FieldGateway/NodeJS

This folder includes Azure IoT Gateway example projects for NodeJS including a demo device simulator and a sample gateway that implements batch messaging and compression. Note: this sample will only run on x86 compatible architectures.

Prerequisites

  • x86 compatible architecture.
  • NodeJS installed

Getting Started

  • In the root of the project run npm install
  • Open the gateway.json file and update the connection string under the iothub_writer module to map to your IoT Hub connection string. The connection string should include the registerd device id of the field gateway; i.e. HostName=foo.bar.azure-device.net;DeviceId=foo;SharedAccessKey=bar
  • Open a terminal window in the FieldGateway/nodejs folder and run the following command: `.\bin\gateway.exe
  • Open a second terminal window in the FieldGateway/nodejs/device_simulator folder and run the following command: node simulator.js

The device simulator will begin pushing messages at the field gateway, which will in turn, batch 10 messages, compress and forward to your IoT Hub.
