OpenThread Co-Processor
|
|
#######################
|
|
|
|
Overview
|
|
********
|
|
|
|
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 https://openthread.io/platforms/co-processor.
|
|
|
|
Additional required host-side tools (e.g. otbr-agent) to build a Thread Border
|
|
Router can be obtained by following
|
|
https://openthread.io/guides/border-router/build#set-up-the-border-router.
|
|
|
|
The preferred Co-Processor configuration of OpenThread is RCP now.
|
|
|
|
The source code for this sample application can be found at:
|
|
:zephyr_file:`samples/net/openthread/coprocessor`.

|
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
|
|
:compact:
|
|
|
|
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
|
|
:compact:
|
|
|
|
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
|
|
:compact:
|
|
|
|
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
|
|
configuration.
|
|
|
|
- :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.
