802.15.4 “serial-radio” sample¶
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.
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:
$ 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
prj.confThis is the standard default config. This can be used by itself for hardware which has native 802.15.4 support.
overlay-cc2520.confThis overlay enables support for CC2520 transceiver
overlay-rf2xx.confThis overlay enables support for RF2XX transceiver
To build the wpan_serial sample:
west build -b <board name> samples/net/wpan_serial -- -DCONF_FILE="prj.conf [overlay-<RADIO>.conf]"
Here’s how to build and flash the sample for the Atmel SAM R21 Xplained Pro Development Kit. Note that for this SoC, you don’t need to include
west build -b atsamr21_xpro samples/net/wpan_serial west flash
Connect board to Linux PC, /dev/ttyACM[number] should appear.
Run Contiki-based native border router (6lbr, native-router, etc) Example for Contiki:
$ 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.
... 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.
