send() returns fail when it is still working on a message
(and for reasons...), so this may indicate that you are
trying to send too fast. That's the original point of the
pending state variable, so make sure you have that logic
worked out correctly.

Hi Urs,
Thanks for your suggestion. I tried and got the same result. Seems that the
call SendMsg.send(TOS_BCAST_ADDR, sizeof(IkTestMsg), &local_msg);
returns SUCCESS only for the first time it's called. If I put the
pending = FALSE;
in if-statement, it'll always make the if condition in the event
SendMsg.sendDone() return FALSE.
Any further suggestions would be appreciated.

Hi,
In the task SendPacket() you always set pending to FALSE. Try to set it
only to false if there was an error:
task void SendPacket() {
IkTestMsg *message = (IkTestMsg *)local_msg.data;
if (!pending)
{
pending = TRUE;
message->addr = TOS_BCAST_ADDR;
message->cnt = counter;
atomic {
message->src = TOS_LOCAL_ADDRESS;
}
if (call SendMsg.send (TOS_BCAST_ADDR, sizeof(IkTestMsg),
&local_msg))
{
dbg(DBG_USR1, "Sending Message\n");
dbg(DBG_USR1, "Source address = %d\n", message->src);
dbg(DBG_USR1, "Value = %d\n", counter);
pending = FALSE;
}
}
dbg(DBG_USR1, "Pending message in buffer!\n");
}
Cheers,
