Hello all,
I am working with tinyos-1.x and using tmote sky.
I wanted to know when exactly is sendDone signaled. Is it signaled
when the last bit is transmitted over the radio or when the message is
transfered to radio and waiting to be transmitted over air or
something else?
I was under the impression that sendDone is signaled when the message
is transmitted over the radio (air) but I came across this code for
timestamping where the call to add timestamp is done inside the
implementation of the event sendDone.
event result_t SendMsg.sendDone(TOS_MsgPtr mptr, result_t res) {
call TimeStamp.addStamp(mptr,SEND_OFFSET);
return res;
} // End event SendMsg.sendDone()
Clearly, if Timestamping is done after sendDone is signaled, it means
that the message is still not transmitted over air.
Kindly help.
Thanks in advance,
Gaurav
