Hi all,
I've played arround with the parameters and now it works as expected.
With the newest tinyos trunk (rev 4941). I have set
LowPowerListeningConfig.getListenLength() to 38ms instead of 5ms (this
corresponds the length of 1600 cca checks on telosb motes) and
set LocalWakeupInterval to 500
and RemoteWakeupinterval to 550.
In the TestLpl app I don't understand these lines of Code.
if (sendInterval >= 0)
call LowPowerListening.setRemoteWakeupInterval(&packet,
sendInterval);
which value has RemoteWakeupInterval if sendInterval is lesser than 0 ?
