================ |
||||
This application is a showcase for testing LWMAC communications. Using it |
||||
for your board, you should be able to interactively use any hardware |
||||
that is supported for communications among devices based on LWMAC. |
||||
|
||||
Usage |
||||
===== |
||||
|
||||
Build, flash and start the application: |
||||
``` |
||||
export BOARD=your_board |
||||
make |
||||
make flash |
||||
make term |
||||
``` |
||||
|
||||
The `term` make target starts a terminal emulator for your board. It |
||||
connects to a default port so you can interact with the shell, usually |
||||
that is `/dev/ttyUSB0`. If your port is named differently, the |
||||
`PORT=/dev/yourport` variable can be used to override this. |
||||
|
||||
|
||||
Example output |
||||
========== |
||||
|
||||
The `ifconfig` command will help you to configure all available network |
||||
interfaces. On an samr21 board it will print something like: |
||||
``` |
||||
2015-09-16 16:58:37,762 - INFO # ifconfig |
||||
2015-09-16 16:58:37,766 - INFO # Iface 4 HWaddr: 9e:72 Channel: 26 NID: 0x23 TX-Power: 0dBm State: IDLE CSMA Retries: 4 |
||||
2015-09-16 16:58:37,768 - INFO # Long HWaddr: 36:32:48:33:46:da:9e:72 |
||||
2015-09-16 16:58:37,769 - INFO # AUTOACK CSMA |
||||
2015-09-16 16:58:37,770 - INFO # Source address length: 2 |
||||
``` |
||||
|
||||
The `txtsnd` command allows you to send a simple string directly over the link |
||||
layer (here, it is LWMAC) using unicast or broadcast. The application will also automatically print |
||||
information about any received packet over the serial. This will look like: |
||||
``` |
||||
2015-09-16 16:59:29,187 - INFO # PKTDUMP: data received: |
||||
