 4) Wait until red LED toggles on mote 2 (server)
 5) Choose "Click button on Sky 3" from the context menu of mote 3 (client) and watch serial output
 
-TMOTES HOWTO
-------------
-Server:
-1) Connect two Tmote Skys (check with $ make TARGET=sky sky-motelist)
-2) $ make TARGET=sky er-example-server.upload MOTE=2
-3) $ make TARGET=sky login MOTE=2

-7) $ make connect-router

-8) Start Copper and discover resources at coap://[aaaa::____:____:____:____]:5683/

-Add a client:
-1) Change the hard-coded server address in er-example-client.c to aaaa::____:____:____:____
-2) Connect a third Tmote Sky
-3) $ make TARGET=sky er-example-client.upload MOTE=3
