Problem with getting data from XB S1 in Cyclic Sleep Mode

Hello,

I make a project composed of 3 End Devices with analog sensors connected, sending data to Coordinator connected to Arduino. Everything worked fine, until i tried to put end devices in sleep mode. I receive no data on my coordinator. I’ve tried several configurations but still with the same results.
This is my current configuration:
COORDINATOR
SM 0
ST 2710
SP 3E8
SO 0
AP 2

END DEVICE
SM 5
ST 2710
SP 3E8
SO 0
IR FFFF
IT 1
AP 2

If anybody had idea what i’m doing wrong - i will be really thankfull for answer

What is CE, A1 and A2 set to on your devices?
