Network steering is failing

Hello, I am beginner and I am working on the code for a coordinator node now. For the second node (router) on the network, i am using a DR1174+DR1199+the deafult application-JN-AN-1219.

During testing , when network steering is started from the router, i see on the Ubiqua protocol analyser that the MAC association sequence happens successfully, but there is a problem in the consequent communication - The router continues to send Data.request commands and the co-ordinator sends back, what looks like incomplete frames. i have attached the screen shot from the protocol analyzer below.

I see in the program of the router that  function ZPS_eAplZdoJoinNetwork starts the Asociation sequence.

I dont undertsnad the following :

  • As  a part of Network steering, even after the Assciation is a success, why is the router sending data request  ? What is the design behind ?
  • I assume that the program in the corordinator has problems and so it sends invalid frames to the data.request. What should be done in the Co-ordinator program that he sends correct response ?

 

I would appreciate any leads to solution. Thanks !!
