View source on GitHub

This guide covers the basic build and configuration of OpenThread Commissioner (OT Commissioner). Upon completion of this procedure, you'll have an OT Commissioner CLI executable and a static Commissioner library.

Set up OT Commissioner

1. Clone the OT Commissioner repository:

   git clone https://github.com/openthread/ot-commissioner
   

2. Install dependencies:

   cd ot-commissioner
   ./script/bootstrap.sh
   

Build OT Commissioner

OT Commissioner installs to the /usr/local directory. If you'd like to change your installation directory, set -DCMAKE_INSTALL_PREFIX.

1. Build OT Commissioner:

   mkdir build
   cd build
   cmake -DCMAKE_INSTALL_PREFIX=/usr/local -GNinja ..
   ninja -j1
   

2. Create an Environment variable to run commissioner-cli in the next step:

   export COMMISSIONER_CLI=/usr/local/bin/commissioner-cli
   

3. Optional. Run unit tests:

   ./tests/commissioner-test
   

Install OT Commissioner

OT Commissioner installs the following to your installation directory:

• OT Commissioner library and header files
• OT Commissioner CLI executable binary
• Default configuration files and credentials
• Scripts to run OT Commissioner CLI as daemon

sudo ninja install

Verify the installation by checking the help menu.

$COMMISSIONER_CLI -h

If you installed to the /usr/local directory, commissioner-cli is available from the command line.

commissioner-cli -h

Configuration

The OT Commissioner CLI supports both Thread 1.2 Commercial Commissioning Mode (CCM) and Thread 1.1 commissioning (Non-CCM). To connect to different Thread networks, a JSON configuration file is needed to start OT Commissioner CLI:

• ccm-config.json — The default configuration file for CCM Thread Network.
• non-ccm-config.json — The default configuration file for Non-CCM Thread Network.

By default, these configuration files are installed in /usr/local/etc/commissioner. You can also view sample files on the ot-commissioner GitHub repository.

CCM configuration

To connect to a CCM Thread network, update these fields in ccm-config.json:

These key and certificate files are used to establish secure sessions between the Commissioner and Border Agent.

Non-CCM configuration

The Pre-Shared Key PSKc is used to establish a secure session between the Commissioner and Border Agent. To connect to a Non-CCM Thread network, you can set your PSKc from the OT Commissioner CLI. For more information, refer to External Commissioning.

Logging

When you run pi@raspberrypi: commissioner-cli from the command line, OT Commissioner creates a commissioner.log file in the current working directory, for example /home/pi/commissioner.log. In the JSON configuration file, you can configure your LogFile path, logging level, and other log settings.

Load configuration

To start OT Commissioner with your configuration settings:

commissioner-cli /usr/local/etc/commissioner/ccm-config.json

Commission a joiner

To use OT Commissioner to commission a joiner, refer to External Commissioning.
