[Tinyos-help]: SimpleCMD can't receive message (anotherstrangephenonmenon)

[Renee Azhen]

Thanks for you attention, Michael,
  In fact, What I want to do is just send a .txt file from the PC to a node via the UART, then the node transfer it to a remote node via RF.
  Do you help any code for this implementation, or could you tell me some link to get this demo??
   
  thanks
  Sam

  If I understand correctly, your TOSBase mote is flashing LEDs
when you try to send a message so that means that your baud
rate and such are probably correct on the PC side. But your
re-Mote is not receiving anything...

It's possible that SimpleCmd expects to get a message to a
specific moteID, I'd have to go look through all the code...
See if you can get it to accept a message with a BCAST address.

Have you had these devices successfully using the radio at all?
You might try something a little simpler like CntToRfm to see
if you get any communication. And make sure you've compiled
all the programs with the same radio channel defined.

I don't know why adding TimerC to the TOSBase config is
troublesome. I have done just that for mica2's to add some
bit twiddling outputs to my base-station. What is the actual
error message you get?

But adding new radio code is probably a recipe for disaster
since TOSBase uses a bunch of lower level functions to do it's
magic, so I'd just leave it well enough alone.

I think what you see in RadioSend is the initial byte send,
subsequent bytes get sent from an interrupt routine somewhere
else in the code there.
