CC2538: zigbee afIncomingMSGPacket_t not giving endpoint

Couldn’t understand your question well? Can you elaborate what you want to achieve?

I want to get coordinator endpoint using afIncomingMSGPacket_t when my device gets connected in network.

for now when i send ON command from server
My device zclonoffCB function is execuited.
Inside my zclonoffCB function i have written below code to get coordinator primary end point

afIncomingMSGPacket_t *pPtr = zcl_getRawAFMsg();

Here if i debug and monitor pPtr variable i can see
scrAddr->endPoint giving me the primary endpoint of coordinator and
scrAddr->panId giving me pan id of coordinator.

I want to achieve same thing when my device joins the network, is there any callback that is called immediately my device joins the network so i need not wait for user to send ON from server and then proceed further.

This is incorrect way to get active endpoint. I suppose you should call ZDP_ActiveEPIFReq from your device to request active endpoint from coordinator.

Not only end point, basically i want to know details like pan id, endpoint etc of the coordinator once my device connects in its network. I would prefer to have a callback for this or is there any better solution.
