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
