Cannot read packet from end node to coordinator

Projects Networking, Protocols, and Devices

Hello,
I have an issue to read packets sent from end node to the coordinator. The packet is well sent. I can see it when I connect the xbee to XCTU. When I place it on the xbeeshield, I have an issue to get the packet in the arduino.
At the coordinator, when the data is sent, on the xbeeshield, the RSSI is on and the DOUT is blinking. On the monitor, I get Error code:3.

Any idea what is wrong?
Thanks!

MY on one should be DL on the other. You do not have your XBees configured to talk to each other, if that information is correct. Do not use 0xFFFF as the address of either XBee.
