I'm using 3 ESP8266 for my project: one ESP8266 is a server and controls any action.
I want to be able to connect to any ESP8266 with a phone and if that ESP8266 is a client, send data to the server.
I'm using TCP/IP for communication between ESP8266 models and ESP8266 with PC or phone.
My problem is with the number of clients. In ESP8266, a maximum of 5 TCP clients can connect to a server, and my master ESP8266 is using 2 (to connect to the other ESP8266), so that just leaves 3 clients (PC or phone) that can connect to the master ESP8266.
Is there any way to increase the number of clients?
Is there any alternative for communicating between ESP8266 models other than TCP/IP and leave 5 clients in ESP8266 for the user to connect?
