This is a Python implementation of Bluetooth-Based Thread Commissioning client, based on Thread's TCAT (Thread Commissioning over Authenticated TLS) functionality.
If you don't have the poetry module installed (check with poetry --version), install it first using:
python3 -m pip install poetry
Thread uses Elliptic Curve Cryptography (ECC), so we use the ecparam openssl argument to generate the keys.
poetry install
This will install all the required modules to a virtual environment, which can be used by calling poetry run <COMMAND> from the project directory.
In order to connect to a TCAT device, enter the project directory and run:
poetry run python3 bbtc.py {<device specifier> | --scan}
where <device specifier> can be:
--name <NAME> - name advertised by the device--mac <ADDRESS> - physical address of the device's Bluetooth interfaceUsing the --scan option will scan for every TCAT device and display them in a list, to allow selection of the target.
For example:
poetry run python3 bbtc.py --name 'Thread BLE'
The application will connect to the first matching device discovered and set up a secure TLS channel. The user is then presented with the CLI.
The application supports the following interactive CLI commands:
help - Display available commands.commission - Commission the device with current dataset.thread start - Enable Thread interface.thread stop - Disable Thread interface.hello - Send “hello world” application data and read the response.exit - Close the connection and exit.dataset - View and manipulate current dataset. See dataset help for more information.
