Device Provisioning Service Client

The Device Provisioning Service Client provisions devices with an Azure IoT Hub using the Azure Device Provisioning Service and creates/updates the chirpstack-gateway-bridge config file with the Azure IoT Hub connection information.

Build with Docker (Recommended)

To build and package the dps-client binary using Docker, run the following command:

docker run -v $PWD:/opt/dps-client -it mydevices/dps-client:dev-build /bin/bash

This will mount the current directory to the /opt/dps-client directory in the container. The dps-client source code is located in the /opt/dps-client directory in the container.

To build the dps-client binary, run the following command:

make multitech

Build Locally

To build for the current OS:

make

To cross compile for a specific architecture:

make <TARGET_ARCH>

Where TARGET_ARCH is one of the following: armv5, armv7, mips, mipsle.

This command will build the dps-client at build/<TARGET_ARCH>. The binary can be run with the parameters below and will output a config file if provisioning is successful. The config file is used with the chirpstack-gateway-bridge binary.

Package

To create an opkg package for a specific gateway you can use the provided makefile targets. This requires opkg-utils to be installed locally. This can be done by cloning the opkg-utils repo and running make install from the opkg-utils root directory.

make <MANUFACTURER>

Where MANUFACTURER is one of the following: kerlink, multitech, tektelic or gemtek. The package will be created at build/package/<MANUFACTURER>.

Docker

A Dockerfile is provided for ease of compiling on other architectures

1. build image

docker build -t mydevices/dps-client:latest .

2. run headless container

Example of how to run the binary

docker run -w ./ -i -t mydevices/dps-client:latest /opt/dps-client/dps-client --help 

docker run -v $(pwd):'/home/' -i -t mydevices/dps-client:latest /opt/dps-client/dps-client -e global.azure-devices-provisioning.net -s 0ne0006B4D6 -r GATEWAY_ID -c /home/GATEWAY_ID.cert.pem -k /home/GATEWAY_ID.key.pem  -o /home/chirpstack-gateway-bridge.toml

The above command assumes that the current host has the certificates in a local directory. (pwd)

Usage

The dps-client can provision devices using options from a specified input config file. It is recommended to use a default.toml file like the ones under the packaging/<manufacturer>/files folders and specify the device ID and cert file paths on the command line. If using an input file it must contain the [integration] section like the ones under the packaging/<manufacturer>/files folders.

[integration]
  marshaler = "json"

  [integration.mqtt]

    [integration.mqtt.auth]
      type = "azure_iot_hub"

        [integration.mqtt.auth.azure_iot_hub.provisioning]
          endpoint = "global.azure-devices-provisioning.net"
          scope = "0ne0006B4D6"

If support for gateway commands (reboot, remote-ctrl and update) are needed a [commands] section is also required and a command-ctrl.sh script will need to be created for the target device. Examples of the command-ctrl.sh script are also under the packaging/<manufacturer>/files folders.

[commands]

  [commands.commands]

    [commands.commands.reboot]
      command = "/opt/mydevices/command-ctrl.sh reboot"
      max_execution_duration = "1s"

    [commands.commands.remote-ctrl]
      command = "/opt/mydevices/command-ctrl.sh remote-ctrl"
      max_execution_duration = "15s"

    [commands.commands.update]
      command = "/opt/mydevices/command-ctrl.sh update"
      max_execution_duration = "20m"

Command with an input toml file specified:

dps-client -i /path/to/default.toml -r <DEVICE_ID> -c /path/to/device/cert.pem -k /path/to/device/key.pem -o /path/to/output_config.toml

Alternatively the dps-client can be run without an input toml file by specifying the endpoint and scope id on the command line. In this case a standard default config file will be generated. The available command line options are specified below.

Usage of ./dps-client:
  -c string
        Full path to the device certificate
  -e string
        Device provisioning Endpoint URI (default "global.azure-devices-provisioning.net")
  -i string
        Input file containing the opts settings
  -k string
        Full path to the device private key
  -o string
        Output file containing the opts settings
  -p string
        Protocol to use when provisioning device, mqtt or https (default "mqtt")
  -r string
        Registration ID of the device
  -s string
        Device provisioning scope ID
  -t    Output trace info
  -v    Output version info
