Hi,
I did the following:
event result_t RsendMsg.sendDone(TOS_MsgPtr msg, result_t success)
{
result_t txmode,sndmsg;
TOSH_uwait(1000);
do{
/*LOOP 1*/
txmode = call CC1000Control.RxMode();
}while(!txmode);
if ( txmode == SUCCESS )
call CLeds.yellowOff();
do{
/* LOOP2*/
sndmsg = call RsendMsg.send(TOS_BCAST_ADDR,12,msg);
}while(!sndmsg);
if ( sndmsg == SUCCESS )
call CLeds.yellowOn();
return SUCCESS;
}
If I remove LOOP 1, then retransmissions occur.But, when LOOP 1 is
included no retransmissions occur.
What could be the reason.?
Regards,
Kishore
