Hi all,
Made a very simple program to test LPL but am not sending/receiving
any messages or sometimes only 1 (depending on the LPL_INTERVAL
value). Can someone tell me what am I doing wrong?
Thanks in advance
Here's the code:
Test.h
#ifndef TEST_H
#define TEST_H
enum {
AM_TEST = 6,
TIMER_PERIOD_MILLI = 250,
LPL_INTERVAL = 2000
};
typedef nx_struct TestMsg {
nx_uint16_t nodeid;
} TestMsg;
#endif
TestAppC.nc
#include <Timer.h>
#include "Test.h"
configuration TestAppC {
}
implementation {
components MainC;
components TestC as App;
components new TimerMilliC() as Timer0;
components ActiveMessageC;
components new AMSenderC(AM_TEST);
components new AMReceiverC(AM_TEST);
components CC2420ActiveMessageC as LPLProvider;
App.Boot -> MainC;
App.Timer0 -> Timer0;
App.Packet -> AMSenderC;
App.AMPacket -> AMSenderC;
App.AMControl -> ActiveMessageC;
App.AMSend -> AMSenderC;
App.Receive -> AMReceiverC;
App.LPL -> LPLProvider;
}
TestC.nc
#include <Timer.h>
#include "Test.h"
module TestC {
uses interface Boot;
uses interface Timer<TMilli> as Timer0;
uses interface Packet;
uses interface AMPacket;
uses interface AMSend;
uses interface Receive;
uses interface SplitControl as AMControl;
uses interface LowPowerListening as LPL;
}
implementation {
void sendMessage();
task void sendMessageTask();
message_t pkt;
bool busy = FALSE;
event void Boot.booted() {
call LPL.setLocalSleepInterval(LPL_INTERVAL);
call AMControl.start();
}
event void AMControl.startDone(error_t err) {
if (err == SUCCESS) {
call Timer0.startPeriodic(TIMER_PERIOD_MILLI);
}
else {
call AMControl.start();
}
}
event void AMControl.stopDone(error_t err) {
}
event void Timer0.fired() {
// if (!busy) {
TestMsg* tpkt =
(TestMsg*)(call Packet.getPayload(&pkt, sizeof(TestMsg)));
if (tpkt == NULL) {
return;
}
tpkt->nodeid = TOS_NODE_ID;
sendMessage();
//}
}
void sendMessage() {
call LPL.setRxSleepInterval(&pkt, LPL_INTERVAL);
if (call AMSend.send(AM_BROADCAST_ADDR,
&pkt, sizeof(TestMsg)) == SUCCESS) {
busy = TRUE;
}
else post sendMessageTask();
}
task void sendMessageTask() { sendMessage(); }
event void AMSend.sendDone(message_t* msg, error_t err) {
if (&pkt == msg) {
if (err != SUCCESS)
post sendMessageTask();
else
busy = FALSE;
}
}
event message_t* Receive.receive(message_t* msg, void* payload,
uint8_t len){
if (len == sizeof(TestMsg)) {
TestMsg* tpkt = (TestMsg*)payload;
}
return msg;
}
}
