Hi ,
I posted this question a few days back. Posting it again as someone
might have missed it due to flurry of emails in this list. Any pointers
on LPL question will be appreciated.
Michael, Thanks for the response. The MacControl Interface in mica2 is
not ported to TOSSIM CC1000Radio implementation.
Thanks,
Vinai.

can't help with the main LPL question, but search back on the
list for a few weeks for "ACK". I periodically send out "advice"
on that...

Hi ,
I notice that when I put the CC1000Radio (in tos/platform/pc ) in low
power listening(LPL) mode, the application loses packets although
lossy radio model is not used. The event sendDone gets called on the
sender side but the receiver does not receive the packet. When I put
debug statements to observe radio operations, I found that receiver
mote does not get a chance to run until the sendDone is called on the
sender mote. I set both the listening mode and transmit mode to the
same value as explained in the CC1000Radio Manual (
http://www.tinyos.net/tinyos-1.x/doc/mica2radio/CC1000.html ). The
same behavior happens irrespective of the mode except "always on"
mode. When I use the radio on always on mode, no packets are lost and
everything works fine. Why does LPL makes packets to be lost? Also,
how to enable ack on CC1000Radio ( tos/platform/pc )? Any pointers
are appreciated.
Thanks,
Vinai.
