XT Cyclic Sleep Mode

I am having some issues with cyclic sleep mode working correctly. I changed the configuration for the transmitter for LH (Wakeup Initializer Timer) to 0x0B. I changed the receiver Sleep Mode (SM) to 4 for 1 second cyclic sleep. It does not work for me. No matter what I try, every time I change the receiver to SM=4, it doesn’t work. If I change it back to SM=0 (Sleep Disabled), it works fine. I am at a loss.

The issue you are experiencing is a result of the wake up initialize not being long enough. Try following the steps at http://www.digi.com/support/kbase/kbaseresultdetl?id=2040. It should help you resolve this situation.
