OpenThread Co-Processor
OpenThread Co-Processor allows building a Thread Border Router. The code in this
sample is only the MCU target part of a complete Thread Border Router.
The Co-Processor can act in two variants: Network Co-Processor (NCP) and Radio
Co-Processor (RCP), see
Additional required host-side tools (e.g. otbr-agent) to build a Thread Border
Router can be obtained by following
The preferred Co-Processor configuration of OpenThread is RCP now.
The source code for this sample application can be found at:
Building and Running
Build the OpenThread NCP sample application like this:
.. zephyr-app-commands::
:zephyr-app: samples/net/openthread/coprocessor
:board: <board to use>
:conf: <config file to use>
:goals: build
Build the OpenThread NCP sample application which uses CDC ACM UART device:
.. zephyr-app-commands::
:zephyr-app: samples/net/openthread/coprocessor
:board: nrf52840dk_nrf52840
:goals: build flash
:gen-args: -DDTC_OVERLAY_FILE=usb.overlay -DOVERLAY_CONFIG=overlay-usb-nrf-br.conf
Example building for the nrf52840dk_nrf52840 for RCP:
.. zephyr-app-commands::
:zephyr-app: samples/net/openthread/coprocessor
:host-os: unix
:board: nrf52840dk_nrf52840
:conf: "prj.conf overlay-rcp.conf"
:goals: run
There are configuration files for different boards and setups in the
coprocessor directory:
- :file:`prj.conf`
Generic NCP config file. Use this, if you want the NCP configuration.
- :file:`overlay-rcp.conf`
RCP overlay file. Use this in combination with prj.conf, if you want the RCP
- :file:`overlay-tri-n4m-br.conf`
This is an overlay for the dedicated Thread Border Router hardware
The board support is not part of the Zephyr repositories, but the
product is based on NXP K64 and AT86RF233. This file can be used as an
example for a development set-up based on development boards.
