802.15.4 "serial-radio" sample
##############################
Overview
********
The wpan_serial sample shows how to use hardware with 802.15.4 radio and USB
controller as a "serial-radio" device for Contiki-based border routers.
Requirements
************
The sample assumes that 802.15.4 radio and USB controller are supported on
a board. You can pick, for example, a transceiver such as a CC2520 or RF2xx
using overlays, or by using an SoC with a built-in radio, such as a kw41z,
nrf5, or samr21.
Building and Running
********************
#. Before building and running this sample, be sure your Linux system's
ModemManager is disabled, otherwise, it can interfere with serial
port communication:
.. code-block:: console
$ sudo systemctl disable ModemManager.service
#. Build the sample Zephyr application to a board with a 802.15.4 radio
and USB controller. There are configuration files for various setups
in the ``samples/net/wpan_serial`` directory:
- :file:`prj.conf`
This is the standard default config. This can be used by itself for
hardware which has native 802.15.4 support.
To build the wpan_serial sample:
.. zephyr-app-commands::
:zephyr-app: samples/net/wpan_serial
:board: <board name>
:conf: "prj.conf [overlay-<RADIO>.conf]"
:goals: build
:compact:
Here's how to build and flash the sample for the Atmel SAM R21
Xplained Pro Development Kit.
.. zephyr-app-commands::
:zephyr-app: samples/net/wpan_serial
:board: atsamr21_xpro
:goals: build flash
:compact:
#. Connect board to Linux PC, /dev/ttyACM[number] should appear.
#. Run Contiki-based native border router (6lbr, native-router, etc)
Example for Contiki:
.. code-block:: console
$ cd examples/ipv6/native-border-router
$ make
$ sudo ./border-router.native -v5 -s ttyACM0 fd01::1/64
Now you have a Contiki native board router. You can access its web-based
interface with your browser using the server address printed in the
border-router output.
.. code-block:: console
...
Server IPv6 addresses:
0x62c5c0: =>fd01::212:4b00:531f:113a
...
Use your browser to access ``http://[fd01::212:4b00:531f:113a]/`` and you'll
see available neighbors and routes.
