hi all,
I want to send a data to a node which is not in senders transmission range.
So, i am planning to use multihop trnasmission. (T2 & TOSSIM)
So, i tried to extract the things that the multihop transmission is needed
from the MultihopOscilloscope application. that means, i am not interested
in sending data to the root node via the serial communication. So i ignored
that part and re-written an application only for multihop transmission. it
is very simple and follwing are the list of codes. It reads the data once
the tin=mer fired and then send the data through multihop transmission
method.
my problem is: I get the debuging mesaages until ReadDone, but not after. It
never print the debugging statement in the if block which sends the data. I
have included my sourse code and sample out put. if somebody can point me
out my mistake, i'll really appriciate it. Am i missing something? i feel
so, but cannot find it.
MultihopOscilloscopeC.nc
===================
#include "Timer.h"
#include "MultihopOscilloscopeC.h"
module MultihopOscilloscopeC {
uses{
interface Boot;
interface SplitControl as RadioControl;
interface StdControl as RoutingControl;
interface Send;
interface Receive as Snoop;
interface CollectionPacket;
interface Timer<TMilli>;
interface Read<uint16_t>;
}
}
implementation{
message_t sendbuf;
oscilloscope_t local;
bool sendbusy =FALSE;
event void Boot.booted(){
dbg("vsn","Booted\n");
call Timer.startOneShot(50);
}
event void Timer.fired(){
dbg("vsn","Timer fired\n");
call Read.read();
}
event void Read.readDone(error_t result, uint16_t data){
oscilloscope_t *o = (oscilloscope_t*)call
Send.getPayload(&sendbuf);
dbg("vsn","readDone\n");
local.senderId=TOS_NODE_ID;
local.receiverId= 5;
memcpy(o,&local,sizeof(local));
if(call Send.send(&sendbuf,sizeof(local))==SUCCESS){
sendbusy =TRUE;
dbg("vsn","start multihop\n");
}
}
event void Send.sendDone(message_t *msg, error_t error) {
sendbusy = FALSE;
dbg("vsn","sendDone\n");
}
event message_t* Snoop.receive(message_t* msg,void* payload ,
uint8_t len){
dbg("vsn","Snoop.receive\n");
return msg;
}
event void RadioControl.stopDone(error_t error) { }
event void RadioControl.startDone(error_t error) { }
}
MultihopOscilloscopeAppC.nc
=============================
configuration MultihopOscilloscopeAppC{}
implementation {
components MainC;
components MultihopOscilloscopeC;
components new TimerMilliC();
components SensorC;
components CollectionC as Collector;
components ActiveMessageC;
components new CollectionSenderC(AM_OSCILLOSCOPE);
MultihopOscilloscopeC.Boot->MainC;
MultihopOscilloscopeC.RadioControl->ActiveMessageC;
MultihopOscilloscopeC.RoutingControl->Collector;
MultihopOscilloscopeC.Send ->CollectionSenderC;
MultihopOscilloscopeC.Snoop->Collector.Snoop[AM_OSCILLOSCOPE];
MultihopOscilloscopeC.Timer->TimerMilliC;
MultihopOscilloscopeC.Read->SensorC;
}
