Hi everyone,
Recently, I've been trying implementing LPL on irismote, with
tinyos-2.x. Yet one problem occured
I found in * LowPowerListening *interface the command of getting and
setting local sleep interval, and write code as follows, which simply
setting the sleep interval and trying to read the set value:
// receive dataMsg from the sink node
dutyCycle = ((data_msg_t*)payload)->dutyCycle;
call LPL.setLocalWakeupInterval(dutyCycle);
.....
// try to read the recent set value
dataMsg->dutyCycle = call LPL.getLocalWakeupInterval();
// then send the 'dataMsg' to sink node and display it on PC
But when the sink node receives the message and recover the *dutyCycle*,
it is always zero filled. I'm sure there is no problem in the transmission
part, because if the node send the received *dutyCycle *directly back to the
PC , it will have the right result. Yet when the dutyCycle is read
by LPL.getLocalWakeupInterval(), it is zero.
I've been stuck here for many days without any progress. Is there
anyone that can help me? Thanks a lot:)
Best wishs,
Fenggang
