Hi all,
I am new to sensor networks. I am working on a project that does load
balancing. But in my project Receive event is not working. So, I tried to
do simple send and receive but no luck.
Please see my code below
implementation {
bool busy = FALSE;
message_t pkt;
uint16_t counter = 1;
bool fwd = FALSE;
/*--------------------------------------------------------------*/
event void Boot.booted() {
call AMControl.start();
}
/*--------------------*/
event void AMControl.startDone(error_t err) {
if (err == SUCCESS) {
call Timer0.startPeriodic(300);
}
else {
call AMControl.start();
}
}
event void AMControl.stopDone(error_t err) {
}
/*-----*/
event void Timer0.fired() {
if (!busy) {
BlinkToRadioMsg* btrpkt = (BlinkToRadioMsg*)(call
Packet.getPayload(&pkt, sizeof (BlinkToRadioMsg)));
btrpkt->nodeid = TOS_NODE_ID;
btrpkt->counter = counter;
if (call AMSend.send(AM_BROADCAST_ADDR, &pkt, sizeof(BlinkToRadioMsg))
== SUCCESS) {
* printf("AM layer sends\n");*
busy = TRUE;
}
}
}
/*------------*/
event void AMSend.sendDone(message_t* msg, error_t error) {
if (&pkt == msg) {
* printf("sent successfully\n");*
busy = FALSE;
}
}
/*-------------*/
event message_t* Receive.receive(message_t* msg, void* payload, uint8_t
len) {
if (len == sizeof(BlinkToRadioMsg)) {
BlinkToRadioMsg* btrpkt = (BlinkToRadioMsg*)payload;
* printf("receive\n");*
call Leds.set(btrpkt->counter);
}
return msg;
}
}
I have installed this on 3 mica2 motes and tested
My output is
AM layer sends
sent succesfully
..
..
But receive is not printing
Please help
