I am working on project related to NodeMCU(esp8266-12E). I want to communicate multiple esp to one point(Access Point).. Please guide me http is ok or TCP/udp?
I actually sent you e-mail earlier. You need to set all the modules to connect to remote AccessPoint, by adding one entry in the AccessPoints collection property, as I have shown in the Servo module as example in my Instructables: http://www.instructables.com/id/ESP8266-and-Visuino-Control-Servo-Remotely-Over-Wi/
Set unique IP for each of the modules on the same subnet as the access point. You can also try to use names and have them register in the DNS, but you will need to experiment a bit with it.
Once they are all on the same subnet, you can use UDP sockets as I have shown in the instructable, or TCP/IP as I will show in one of the following instructables.
