Hi Om, Motes send a packet every 10 minutes.
What should the low power listening duty cycle or sleep interval be for that rate? Any idea what the current draw should be in low power state? I switched from using duty cycle instruction to sleep interval yesterday and, although the current draw varies a lot every now and then, it seems to settle to under 1mA after some time. Correct me if I'm wrong but I should wire Low Power Listening and Splitinit to RF230ActiveMessageC.nC, and Send to CollectionC.nc shouldn't I? The order I'm using is the following: Boot -> LPL.setLocalSleepInterval -> StartCollection -> Start Radio -> ->Radio Started, then Start Periodic Timer -> Timer Fires, call Send Function ->Before using send from the send command, use call LPL.setRxSleepInterval(&msg, LPL_INTERVAL); That's what I'm using at the moment.

I have not personally tried it on IRIS but I have gotten CTP+LPL to achieve 2-4% duty-cycle on TelosB platform - approx 100 nodes, each node sending one data packet every 5 mins.
