[Tinyos-help] Question about send and receive

2009-06-30 Thread sofia aparicio


Hello,

 

I have 3 motes and I want to send data from mote 2 trough mote 1 to the base 
station.

 

Mote 2 call RadioSend.send(data); 

 

RadioReceive.receive(){

if (TOS_LOCAL_ADDRESS == 1){

 call RadioSend.send(data); //Send data to base station (mote 0).

}

 if (TOS_LOCAL_ADDRESS == 0  data is coming from mote 1){

UARTOutput(DBG_ERROR,%s, OutputM);

}

}

 

Mote 1 receives the message but not mote 0. It could be because the base 
station also receives the message from mote 1? 

I tried to wait some time to send the message from mote 1 but mote 0 does not 
receive anything.

Do you know what is the problem?

 

Thank you very much.

 

Sofia

It does not look like you are handling the message buffer correctly in
Receive. You might want to take a look at the documentation of the
Receive interface.

Did you verify that sendDone is signaled correctly on node 1? If not,
your send is not successful.
