I am using an Arduino board with an ESP8266 module to connect to a WiFi device. How do I check if the device is connected?
Firstly,If your ESP8266 module is coded then AT commands won't be responding directly, In that case You can check in Serial monitor(if u already wrote print in the existing code on module) else u have to flash a new code.
If didn't flash any code then use AT commands(AT+CWJAP?) for checking SSID. (AT+ CIPSTATUS) for IP adress.
