I have modified the BlinkToRadio app as follows:
#include <Timer.h>
#include "BlinkToRadio.h"
#include "printf.h"
module BlinkToRadioC {
uses interface Boot;
uses interface Leds;
uses interface Timer<TMilli> as Timer0;
uses interface Packet;
uses interface AMPacket;
uses interface AMSend;
uses interface Receive;
uses interface SplitControl as AMControl;
}
implementation {
uint16_t counter;
message_t pkt, packet;
bool busy = FALSE;
void setLeds(uint16_t val) {
if (val & 0x01)
call Leds.led0On();
else
call Leds.led0Off();
if (val & 0x02)
call Leds.led1On();
else
call Leds.led1Off();
if (val & 0x04)
call Leds.led2On();
else
call Leds.led2Off();
}
event void Boot.booted() {
call AMControl.start();
}
event void AMControl.startDone(error_t err) {
if (err == SUCCESS) {
call Timer0.startPeriodic(TIMER_PERIOD_MILLI);
counter++;
counter++;
//while(busy);
if (!busy) {
BlinkToRadioMsg* btrpkt =
(BlinkToRadioMsg*)(call Packet.getPayload(&packet, sizeof(BlinkToRadioMsg)));
if (btrpkt == NULL) {
return;
}
btrpkt->nodeid = TOS_NODE_ID;
btrpkt->counter = counter;
if (call AMSend.send(AM_BROADCAST_ADDR, &packet, sizeof(BlinkToRadioMsg))
== SUCCESS) {
busy = TRUE;
printf("BlinkToRadioMsg packet sent with success \n");
printf("sizeof(BlinkToRadioMsg)=%i\n",sizeof(BlinkToRadioMsg) );
}
}
else {
printf("channel busy in sending BlinkToRadioMsg\n");
call AMControl.start();
}
printfflush();
}
else {
call AMControl.start();
}
}
event void AMControl.stopDone(error_t err) {
}
event void Timer0.fired() {
// counter++;
// if (!busy) {
// BlinkToRadioMsg* btrpkt =
//(BlinkToRadioMsg*)(call Packet.getPayload(&pkt, sizeof(BlinkToRadioMsg)));
// if (btrpkt == NULL) {
//return;
// }
// btrpkt->nodeid = TOS_NODE_ID;
// btrpkt->counter = counter;
// if (call AMSend.send(AM_BROADCAST_ADDR,
// &pkt, sizeof(BlinkToRadioMsg)) == SUCCESS) {
// busy = TRUE;
// }
// }
}
event void AMSend.sendDone(message_t* msg, error_t err) {
if (&pkt == msg) {
busy = FALSE;
}
}
event message_t* Receive.receive(message_t* msg, void* payload, uint8_t len){
printf("Received packet of length %hhu.\n", len); printfflush();
if (len == sizeof(BlinkToRadioMsg)) {
BlinkToRadioMsg* btrpkt = (BlinkToRadioMsg*)payload;
setLeds(btrpkt->counter);
}
return msg;
}
}
the problem is that only the first message is received.
any help please
