Bad frame counter problem

Dear all,

 

I've just taken a real packet transmission test between a device and Coordinator. There are some strange things happened that I must ask for help. Firstly, let me describe my test scenario:

 

- Network: 1 Coordinator (source code built from JN-AN-1216 project) and 1 Router (source code built from JN-AN-1217 project)

- Router sends Basic report to Coordinator when button is pushed. APS ACK is ON for the packets.

 

Sometimes, when Router sends packet, error "APP-ZDO: Network status Indication 11" occurs on Router or on Coordinartor or on both. This error relates to Bad Frame Counter detection at network layer. I sniff the packet on air and see many packet transmission retries for both Basic Report packet and APS ACK packet. The retry interval is too short (< 10ms). Moreover, the destination does not have time to response MAC ACK while source node retries sending a packet many times. Please find attached for detail. Do you have any suggestion for this problem ?

 

Many thanks.
