I have been able to use the serial pins on the Arduino Mega with no problem and just starting another instance of serial like
Code: Select allSerial1.begin(115200);
and then using the println function in order to send the commands that I want. Software serial is a little bit tricky in that it can't fully understand everything when printing back to the serial monitor. Hope that helps.

This is the ESP8266 Arduino forum: you should ask your question in the ** Newbie Corner **. :idea:

In short, to use AT commands you connect your ESP to a computer, run a terminal program like PuTTY and enter the AT commands on the command-prompt.
For reference (there are hundreds of them), you can follow a guide like on this website.
