#49797 My Robot is controlled using the esp8266 using the serial Monitor of Arduino By Running the AT Commands by programming it. And AT commands runs well But the problem is that while connecting it with USB cable of arduino the serial Monitor wakes up and esp commands runs fair but when usb disconnected esp8266 not able to communicate by giving the external supply. Can I use OLed To run AT command to communicate with ESP8266 because i want My robot to be wireless. Or is there any other method to communicate with ESP8266
I buyed I2c Oled and i dont know how test AT commands in I2C Oled

Please Help me Out with these Issue.
