$ cd tests/hello-world $ make upload $ make login
Working correctly, you should see this:
connecting to /dev/ttyUSB0 (57600) [OK] Power-on reset. External reset! *******Booting Contiki 2.5******* MAC address 2:11:22:ff:fe:33:44:3 nullmac sicslowmac, channel 26 IP addresses [4 max] fdfd::3 fe80::11:22ff:fe33:4403 Hello, world
Now that we know the node itself is working and printing OK, we want to make sure two nodes can talk. The best way to do this is with a ping.
This requires two nodes. If you already have hello-world on one node, the easiest thing to do is to put ping-ipv6 on a second node, and ping the other. So for this example, say we already have hello-world working on node 3 on /dev/ttyUSB0.
$ cd tests/ping-ipv6 $ make upload AVRDUDE_PORT=/dev/ttyUSB1 NODE=3 $ make login AVRDUDE_PORT=/dev/ttyUSB1
Working correctly, you will see this:

Finally, we will want to be sure that two nodes can exchange real application data between them. We can do so with the UDP client/server test. Again, this requires two nodes. One node contains the server program, the other contains the client. When making the client, we need to tell it where to find the server by specifying NODE= the Node# of the server.
$ cd tests/udp-ipv6 $ make udp-server.avr-zigduino.u AVRDUDE_PORT=/dev/ttyUSB0 $ make udp-client.avr-zigduino.u AVRDUDE_PORT=/dev/ttyUSB1 NODE=3 $ make login AVRDUDE_PORT=/dev/ttyUSB0
Working correctly, you'll see something like the following. The exact numbers will depend on the timing of when you do the 'make login'.

The shell is a very powerful feature of Contiki. Within this OS lies a fully-featured command shell. The shell in the avr-zigduino platform is a subset of the full Contiki shell, including only the shell modules which have been proven to work on this platform.
$ cd tests/shell $ make upload $ make login
If successful, you'll see this:
connecting to /dev/ttyUSB1 (57600) [OK] Power-on reset. External reset! *******Booting Contiki 2.5******* MAC address 2:11:22:ff:fe:33:44:1 nullmac sicslowmac, channel 26 Contiki command shell Type '?' and return for help 2.17: Contiki> IP addresses [4 max] fdfd::1 fe80::11:22ff:fe33:4401
Now, try some of the commands, like 'help':
Available commands: ?: shows this help binprint: print binary data in decimal format blink [num]: blink LEDs ([num] times) echo <text>: print <text> exit: exit shell hd: print binary data in hexadecimal format help: shows this help kill <command>: stop a specific command killall: stop all running commands netstat: show UDP and TCP connections null: discard input ping <host>: ping an IP host ps: list all running processes quit: exit shell randwait <maxtime> <command>: wait for a random time before running a command repeat <num> <time> <command>: run a command every <time> seconds size: print the size of the input time [seconds]: output time in binary format, or set time in seconds since 1970 timestamp: prepend a timestamp to data 2.17: Contiki>
Try "blink 100 &" to start blinking the LED's for 100 times. Notice the '&' at the end of that! You should now see all 3 LED's on Zigduino flash on and off repeatedly.
Then type "kill blink" when you're done admiring your blinking lights.
We can also ping from within the shell!
