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
