I have a network of six modules to comunicate two XBP9B-DM Xbee pro modules. They work perfectly in AT mode when the Destination Address is broadcast (0x000000000000FFFF).  
The problem arises when I try to set up the destionation address to be the serial number of one of them. the receiving xbee doesn´t receive any data.

the problem is that now I need to communicate with two final devices (FLOBOSS 103 gas computer flow). I need the address of destination is working to meet the target to communicate with them one by one.

I really appreacite your help

What values are you putting into the DL and DH commands of the receiving module?
