Dear all
I am writing an application in which two consecutive messages are needed to be
sent. Although I check the busy flag ,I get a segment fault error trying to
simulate it with TOSSIM (right after when it tries to send the second message).
Could anyone help me with this?
Here is the actual code which gets the seg fault.
testC.nc
#include "test.h"
module testC{
uses interface Boot;
uses interface AMSend as SendMsg1;
uses interface AMSend as SendMsg2;
uses interface SplitControl as AMControl;
}
implementation{
message_t msg1;
message_t msg2;
bool busy = FALSE;
event void Boot.booted(){
call AMControl.start();
dbg("BOOT", "Booted\n");
}
event void AMControl.startDone(error_t err){
if (err ==SUCCESS)
if(call SendMsg1.send(TOS_BCAST_ADDR, &msg1 ,sizeof(struct TreeReqMsg))==
SUCCESS)
busy =TRUE;
}
event void AMControl.stopDone(error_t err){}
event void SendMsg1.sendDone(message_t* msg, error_t error)
{dbg("BOOT", "msg1 sent done \n");
if (&msg1 == msg)
busy = FALSE;
else {
call SendMsg1.send(TOS_BCAST_ADDR, &msg1 ,sizeof(struct TreeReqMsg));
}
if (busy == FALSE)
call SendMsg2.send(TOS_BCAST_ADDR, sizeof(struct TreeReqMsg),&msg2); ///
here I get the error
}
event void SendMsg2.sendDone(message_t* mg, error_t error){}
}
