Then go through which steps to Dev_zb_coord, Dev_router, Dev_end_device for the above three cases. TI protocol stack is semi-open source, the network layer code is not open source. The ZdO running on Port 0 is responsible for communication between the application-level user program and the network layer. The building process of the network layer is implemented by ZdO. The application layer receives the Zdo_state_change message after the network is established. Use the following statement to read the status of the current network. Genericapp_nwkstate= (devstates_t) (msgpkt->hdr.status);//device type of the Read node
