packet from Coordinator sent twice as shown by Packet Sniffer

Hi,

I'm modifying SimpleApplication project to support 2 way communication between coordinator and an end device (cc2530znp mini kit).

The coordinator sends out a packet, End device receives it and sends back another packet.  I basically combined the pieces of code from Coordinator and End device that are originally provided.

The Coordinator sends out the packet using:

afSendData(DEFAULT_ENDPOINT, DEFAULT_ENDPOINT, 0xFFFF, INFO_MESSAGE_CLUSTER, msgBuf, getSizeOfInfoMessage(&im_coo));

However, using packet sniffer I have noticed that 2 packets are being sent over the air: one to the end device itself and the other is broadcast packet. Why?

After that the Coordinator sends out some "data" type packet with length 11, exactly 6 times. What does it means? The picture from Packet sniffer is in the attachment and this misterious packet is "blue".

 

Please help. I'm running in a circle. Thank you.
