The Arduino IDE can find the IP address of the ESP8266 (mDNS:arduino) when it is programmed with OTA, but we also have ESP-LINK software, which allows the ESP8266 to work in transparent (TCP / IP-Serial) mode allowing reprogramming of microcontrollers like Atmega328 (Arduino UNO / Nano / Pro...

How can I connect Arduino with my cell phone over the internet by using 4G or another wi-fi connection? I'm using udp connection by the way. Should I make any changes on B4R and B4A program? I have a modem1 with external IP and a wi-fi router2 connected to arduino by means of ethernet cable...
