Paul,
Really thanks for your responses.I changed the boot times to 1000,each node
is booted at 1000.
And Node 1 is a sender and every 2000MilliSec sends a packet to
"AM_BROADCAST_ADDR" (I also changed it to the numbers ,like 2 or 0).But
still does'nt worked.In the first time AMSend.send returns a SUCCESS But the
AMSend.sendDone event is not signaled to change the busy flag for later
sends.I also chanaged the busy flag to false but next time AMSend.send
doesn't return SUCCESS .
Paul, should i active the ACK manually ? Or It's Automatically?
*for i in range(0, 3):
m = t.getNode(i);
m.bootAtTime(1000);*
This is the Timer.fired event :
*ent void Timer.fired()
{
counter++;
dbg("Base","Timer fired at %s .\n",sim_time_string());
if(!busy)
{
RbsMsg *data = call Packet.getPayload(&pkt,sizeof(RbsMsg));
data->count = counter;
dbg("Base","data in the packet is : %hhu.\n",data->count);
flag = call AMSend.send(2,&pkt,sizeof(RbsMsg));
if( flag == SUCCESS)
{
dbg("Base","Packet sent %hhu.\n",data->count);
busy = TRUE;
counter++;
}
else
dbg("Base","was not SUCCESSFULL %S.\n",sim_time_string());
}
else
dbg("Control", "the busy flag is true.\n",sim_time_string());
*
************
And this is my message struct :
*enum {
TIMER_DELAY = 2000,
AM_Rbs = 6
};
typedef nx_struct RbsMsg
{
nx_uint8_t count;
} RbsMsg;
#endif
*
