Hi Guys,
I have wrote code for radio to serial communication. When I check this code
manually on motes, it gives me correct data, but when I execute the same code
on Harvard's motelab - for sender's address , I get "1" instead of different
sender addresses. Plz help.
RadioCountToLedsC.nc (Modified original code to make it work for my work)
module RadioCountToLedsC @safe() {
uses {
interface Leds;
interface Boot;
interface Receive;
interface AMSend;
interface Timer<TMilli> as MilliTimer;
interface SplitControl as AMControl;
interface Packet;
interface SplitControl as SerialControl;
interface AMSend as SerialSend;
interface AMPacket;
interface CC2420Packet;
}
}
implementation {
message_t packet;
bool locked;
uint16_t counter = 0;
am_addr_t senderAdd;
int8_t rssiValue=0;
event void Boot.booted() {
call AMControl.start();
call SerialControl.start();
}
event void AMControl.startDone(error_t err) {
if (err == SUCCESS) {
call MilliTimer.startPeriodic(250);
}
else {
call AMControl.start();
}
}
event void SerialControl.startDone(error_t err) {
if (err == SUCCESS) {
// call MilliTimer.startPeriodic(250);
}
else {
call SerialControl.start();
}
}
event void AMControl.stopDone(error_t err) {
// do nothing
}
event void SerialControl.stopDone(error_t err) {
// do nothing
}
event void MilliTimer.fired() {
counter++;
dbg("RadioCountToLedsC", "RadioCountToLedsC: timer fired, counter is
%hu.\n", counter);
if (locked) {
return;
}
else {
radio_count_msg_t* rcm = (radio_count_msg_t*)call
Packet.getPayload(&packet, sizeof(radio_count_msg_t));
if (rcm == NULL) {
return;
}
// rcm->nodeid = TOS_NODE_ID;
// rcm->nodeid = TOS_LOCAL_ADDRESS;
// senderAdd = (am_addr_t) call AMPacket.source(&packet);
// senderAdd = TOS_NODE_ID;
// rcm->senderAdd = senderAdd;
// rcm->senderAdd = TOS_NODE_ID;
rcm->counter = counter;
if (call AMSend.send(AM_BROADCAST_ADDR, &packet,
sizeof(radio_count_msg_t)) == SUCCESS) {
dbg("RadioCountToLedsC", "RadioCountToLedsC: packet sent.\n",
counter); locked = TRUE;
}
}
}
event message_t* Receive.receive(message_t* bufPtr,
void* payload, uint8_t len) {
dbg("RadioCountToLedsC", "Received packet of length %hhu.\n", len);
if (len != sizeof(radio_count_msg_t)) {return bufPtr;}
else {
radio_count_msg_t* rcm1 = (radio_count_msg_t*)call
Packet.getPayload(&packet, sizeof(radio_count_msg_t));
/*
if (rcm->counter & 0x1) {
call Leds.led0On();
}
else {
call Leds.led0Off();
}
if (rcm->counter & 0x2) {
call Leds.led1On();
}
else {
call Leds.led1Off();
}
if (rcm->counter & 0x4) {
call Leds.led2On();
}
else {
call Leds.led2Off();
}
*/
rcm1->senderAdd = (am_addr_t)call AMPacket.source(bufPtr);
rcm1->rssiValue = call CC2420Packet.getRssi(bufPtr);
if (call SerialSend.send(AM_BROADCAST_ADDR, &packet,
sizeof(radio_count_msg_t)) == SUCCESS) {
// locked = TRUE;
}
return bufPtr;
}
}
event void AMSend.sendDone(message_t* bufPtr, error_t error) {
if (&packet == bufPtr) {
locked = FALSE;
}
}
event void SerialSend.sendDone(message_t* bufPtr, error_t error) {
// if (&packet == bufPtr) {
// locked = FALSE;
// }
}
}
This is what I get data from Motelab :
counter senderAdd rssiValue insert_time motelabMoteID
