AsyncTCP With ESP8266

I need some direction I'm sort of stuck and don't know what to do. I want to use ESPAsyncTCP to handle some communications in my project. For me the code is hard to understand i have the client and server example running on 2 ESP's right now to start with. In order for this to work i would need to transfer a data structure through serial to the ESP and then have the esp forward that structure to another ESP and then to to the arduino connected to the other ESP. Right now i use NRF card and all of my slave devices announce data on a timer to a master node. Can someone please give me some advice. i have 8 slave nodes that need to announce to the master node. each node sends a structure of data to the master. What is the best/easiest method i can use to make this work with the esp cards?
