Hi;
i'm newbie at sensor nodes. I am trying to send a message and receive it.
Until now i edit examples. I tried this send, receive applications in this
examples. This is my first implementation without starting from an example. I
install this program to two nodes. Ones has timer, it sends a message every 1
minute and it toggles red led in sendDone function. I see the red led toggling.
The other mote receive this message.When receive this message, it must toggle
green led. But it doesn't do that.
i am sending codes, too. For the receiver node i comment "call
Timer.start(TIMER_REPEAT,1000);" line; so that its timer doesn't work. We must
do this immediately for undergraduate project. After this we will implement a
routing algorithm. Please reply ASAP.
Parent.nc File:
includes deneme;
configuration Parent {
}
implementation {
components Main, ParentM, GenericComm, LedsC, TimerC;
Main.StdControl -> ParentM.StdControl;
ParentM.Send -> GenericComm.SendMsg[AM_INTMSG];
ParentM.Receive -> GenericComm.ReceiveMsg[AM_INTMSG];
ParentM.SubControl -> GenericComm;
ParentM.Leds -> LedsC;
ParentM.Timer -> TimerC.Timer[unique("Timer")];
}
ParentM.nc:
includes deneme;
module ParentM {
provides {
interface StdControl;
}
uses{
interface StdControl as SubControl;
interface SendMsg as Send;
interface ReceiveMsg as Receive;
interface Leds;
interface Timer;
}
}
implementation {
uint16_t cost = 6;
uint16_t parent;
TOS_Msg tempMsg;
command result_t StdControl.init() {
call Leds.init();
call Leds.redOff();
call Leds.yellowOff();
call Leds.greenOff();
call SubControl.init();
return SUCCESS;
}
command result_t StdControl.start() {
call Timer.start(TIMER_REPEAT,1000); //comment this line for
receiving node
return SUCCESS;
}
command result_t StdControl.stop() {
return SUCCESS;
}
event TOS_MsgPtr Receive.receive(TOS_MsgPtr m) {
call Leds.greenToggle();
return m;
}
event result_t Send.sendDone(TOS_MsgPtr msg, result_t success)
{
call Leds.redToggle();
return SUCCESS;
}
event result_t Timer.fired()
{
IntMsg *message = (IntMsg *)tempMsg.data;
message->val = 5;
atomic
{
message->src = TOS_LOCAL_ADDRESS;
}
call Send.send(TOS_BCAST_ADDR,sizeof(IntMsg),&tempMsg);
return SUCCESS;
}
}
deneme.h file:
typedef struct IntMsg {
uint16_t val;
uint16_t src;
} IntMsg;
enum {
AM_INTMSG = 4
};
