timer:
-----
This configuration set the proper configuration to use the timer1 of the board.
This example is configured to work with the USBNSH instead of UART NSH, so

This configuration set the proper configuration to use the timer1 of the
board. This example is configured to work with the USBNSH instead of
UART NSH, so the console will be shown over the USB_OTG1 connector.
On the console, type "ls /dev " and if the registration process goes fine,
you should see a device called "timer1".
mrf24j40-mac:
------------
This configuration set the proper configuration to set the 802.15.4
communication layer with the MRF24J40 radio. This radio works wit
SPI, you need to do the next connections:
MRF24J40 VCC -> Board 3.3V
MRF24J40 GND -> Board GND
MRF24J40 SCLK -> Board PA5 (Arduino header D13)
MRF24J40 MISO -> Board PA6 (Arduino header D12)
MRF24J40 MOSI -> Board PB5 (Arduino header D11)
MRF24J40 CS -> Board PA4 (Arduino header D10)
MRF24J40 INT -> Board PG12 (Arduino header D8)
This example is configured to work with the USBNSH instead of UART NSH,
so the console will be shown over the USB_OTG1 connector.
Once you're on the console, you need to check if the initialization
process was fine. To do so, you need to type "ls /dev" and you should
see a device call "ieee0". At this point we need to set-up the network,
follow the next steps:
This is an example of how to configure a coordinator:
i8sak /dev/ieee0 startpan cd:ab
i8sak set chan 11
i8sak set saddr 42:01
i8sak acceptassoc
This is an example of how to configure the endpoint:
i8sak /dev/ieee0
i8sak set chan 11
i8sak set panid cd:ab
i8sak set saddr 42:02
i8sak set ep_saddr 42:01
i8sak assoc
mrf24j40-6lowpan:
----------------
This configuration set the proper configuration to use 6lowpan protocol with the MRF24J40
radio. This radio works with SPI, you need to do the next connections:
MRF24J40 VCC -> Board 3.3V
MRF24J40 GND -> Board GND
MRF24J40 SCLK -> Board PA5 (Arduino header D13)
MRF24J40 MISO -> Board PA6 (Arduino header D12)
MRF24J40 MOSI -> Board PB5 (Arduino header D11)
MRF24J40 CS -> Board PA4 (Arduino header D10)
MRF24J40 INT -> Board PG12 (Arduino header D8)
This example is configured to work with the USBNSH instead of UART NSH, so
the console will be shown over the USB_OTG1 connector.
Once you're on the console, you need to check if the initialization process
was fine. To do so, you need to type "ls /dev" and you should see a device
call "ieee0". At this point we need to set-up the network, follow the next steps:
This is an example of how to configure a coordinator:
i8sak wpan0 startpan cd:ab
i8sak set chan 11
i8sak set saddr 42:01
i8sak acceptassoc
When the association was complete, you need to bring-up the network:
ifup wpan0
This is an example of how to configure the endpoint:
i8sak wpan0
i8sak set chan 11
i8sak set panid cd:ab
i8sak set saddr 42:02
i8sak set ep_saddr 42:01
i8sak assoc
When the association was complete, you need to bring-up the network:
ifup wpan0
If you execute the command "ifconfig", you will be able to see the info of the WPAN0 interface
and see the assigned IP. This interface can be use with an UDP or TCP server/client application.
