Re: [Contiki-developers] Quick start TmoteSky w/ Contiki Help Needed

[Adam D. <ad...@si...>]

Ok, here is another thing to try. I've compiled a version of the Tmote 
Sky shell with two more debug commands: broadcast and unicast. Here is 
the new .ihex file: 
http://www.sics.se/~adam/tmp/sky-shell-2.2+nodeid+rimedebug.zip

The commands can be used to test single-hop connectivity, like this:

* Connect two nodes to the same PC, install the new sky-shell.ihex 
firmware on both
* Run the following command on one of them: 'repeat 100 1 { echo test | 
broadcast }'
* Open a serial connection to the other one, see if it prints out something

If this works, you can try the unicast command, like this:

'repeat 100 1 { echo test | unicast X.Y }', where X.Y should be replaced 
with the node address of the node to which the packet should be sent.

Also, you can try to turn of the power saving MAC protocol: 'mac 0'.

There may be a lot of conflicting traffic that Contiki picks up. Run 
'sniff | blink | null' and see how much the LED blinks.
