Hi,
First of all sorry for english..
I am Ibrahim Abbas. I am doing graduation from NUST Pakistan. I am having
the following problem in TinyOS.
I am trying to send two different types of packets from node 1 to node 2 ,
where timers for both sendings fire at different intervals, but it is only
sending one type, when I try to send another type of packet then Data2.send
not returns success.
Please see the code below...
In module file..
module RadioCountToLedsC {
uses {
interface Leds;
interface Boot;
interface Receive as Data1;
interface AMSend as data1;
//interface Receive as Data2;
interface AMSend as data2;
interface Timer<TMilli> as MilliTimer;
interface Timer<TMilli> as MilliTimer2;
interface SplitControl as AMControl;
interface Packet as Packet1;
interface Packet as Packet2;
interface Random;
interface LocalTime<TMilli>;
}
}

message_t packet;
message_t packet2;

{
if (err == SUCCESS)
{
/* call MilliTimer2.startPeriodic(25);*/
call MilliTimer.startPeriodic(250);
call MilliTimer2.startOneShot((call Random.rand32() %
SEND_INTERVAL)+(SEND_INTERVAL >> 1));
printf("Timers are Started \n");
}
else
{
call AMControl.start();
}
}
event void AMControl.stopDone(error_t err)
{
// do nothing
}
event void MilliTimer2.fired()
{
if(TOS_NODE_ID==1)
{
dbg("2","MilliTimer2 is Fired After If and Time is %d\n",call
LocalTime.get());
if (locked2)
{
return;
}
else
{
///I think some where here is the problem it does not return
success
other_msg_t* rcm = (other_msg_t*)call Packet2.getPayload(&packet2,
NULL);
call MilliTimer2.startOneShot((call Random.rand32() %
SEND_INTERVAL)+(SEND_INTERVAL >> 1));

}
}
}
}
