WPANUSB sample
##############
Overview
********
This application exports ieee802154 radio over USB to be used in
other OSes such as Linux. For Linux, the ieee802154 stack would be
implemented using the Linux SoftMAC driver.
Requirements
************
- a Zephyr WPANUSB enabled board (such as the :ref:`nrf52840_pca10056`)
connected via USB to a Linux host.
- WPANUSB kernel driver (in the process of being open sourced)
- IWPAN host tools at [http://wpan.cakelab.org/releases/](http://wpan.cakelab.org/releases/)
Building and Running
********************
There are configuration files for various setups in the
``samples/net/wpanusb`` 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.
- :file:`overlay-cc2520.conf`
This overlay config enables support for CC2520
Build the WPANUSB sample like this:
.. zephyr-app-commands::
:zephyr-app: samples/net/wpanusb
:board: <board to use>
:conf: <config file to use>
:goals: build
:compact:
Example building for the Nordic nRF52840 Development Kit:
.. zephyr-app-commands::
:zephyr-app: samples/net/wpanusb
:host-os: unix
:board: nrf52840_pca10056
:goals: run
:compact:
When connected to Linux with wpanusb kernel driver, it is recognized as:
.. code-block:: console
...
T: Bus=01 Lev=02 Prnt=02 Port=00 Cnt=01 Dev#= 3 Spd=12 MxCh= 0
D: Ver= 1.10 Cls=ff(vend.) Sub=00 Prot=00 MxPS=64 #Cfgs= 1
P: Vendor=2fe3 ProdID=0101 Rev=01.00
C: #Ifs= 1 Cfg#= 1 Atr=c0 MxPwr=100mA
I: If#= 0 Alt= 0 #EPs= 1 Cls=ff(vend.) Sub=00 Prot=00 Driver=wpanusb
...
The following script enables the network interface in Linux
(uses iwpan tool from above):
.. code-block:: console
#!/bin/sh
PHY=`iwpan phy | grep wpan_phy | cut -d' ' -f2`
echo 'Using phy' $PHY
iwpan dev wpan0 set pan_id 0xabcd
iwpan dev wpan0 set short_addr 0xbeef
iwpan phy $PHY set channel 0 26
ip link add link wpan0 name lowpan0 type lowpan
ip link set wpan0 up
ip link set lowpan0 up
