Sir,
This project is already working only with adruino builtin serial monitor. You can run this code and check the result that is showing that multiple devices is connecting along with ESP and ESP is working as a router.
I shared all the things with you people and nothing is left to hide. I worked on a journal paper as a contributor and there was an implementation part called “Get smart phones ip & mac addresses through ESP8266 and display it via Blynk”. So i’m working on this part.
