Hi,
I'm trying to send a msg from one mote to another. Mote A has a msg in a
buffer that will send to mote B. Everything works , except in one situation
where mote A sends to mote B, but the msg doesn't get there and consequently
no ack, then in sendDone i repost the task of the msg.
The weird thing is that when i repost the task, the addr should be B, but
for some weird reason the var addr in the repost becomes mote A addr and
enters an infinite loop.
I haven't tested this in real motes, only in tossim, here's a part of the
simulation:
/*.................................*/
DEBUG (4): Reading Sensors for App with id = 1, and sample time = 20
DEBUG (4): Reading of Sensor Temperature is 5221 @ 0:0:20.484296889
DEBUG (4): Reading of Sensor Humity is 7542 @ 0:0:20.484296889
DEBUG (4): Added Alarm Entry

.....

DEBUG (1): source 4
DEBUG (1): Sending to 4

DEBUG (1): Ack for yellow rsp msg not received
DEBUG (1): source 1
DEBUG (1): Sending to 1
DEBUG (1): Ack for yellow rsp msg not received
(loop)
/* ................... */
Here is a part of the code where i send the msg:
/*BEGIN*/
Task void send() {
yellowMsg_t* yellowmsg = (yellowMsg_t*) (call
RadioPacket.getPayload(AlarmQueue[alarmOut], NULL));
.....
busy = TRUE;
yrsp_send = TRUE;
msg = AlarmQueue[alarmOut];
len = call RadioPacket.payloadLength(msg);
source = call RadioAMPacket.source(msg);
yellowmsg->id = YELLOW_RSP;
if (call Sensors.getDefCon(yellowmsg->id,yellowmsg->sensor) != NOT_FOUND)
yellowmsg->alarmType = CONFIRMED;
else
yellowmsg->alarmType = NOT_CONFIRMED;
if (call PacketAck.requestAck(AlarmQueue[alarmOut]) != SUCCESS){
dbg("DTest","requestAck != SUCCESS\n");
call PacketAck.requestAck(AlarmQueue[alarmOut]);
}
if (call AlarmModeSend.send(source, AlarmQueue[alarmOut], len) != SUCCESS) {
call AlarmModeSend.send(source, AlarmQueue[alarmOut], len)
}
}
/* END */
I hope i could express myself well. Anyone had the same problem or similar?
I'm using T2.
Thanks,
Ricardo
