I am trying to use Arduino Nano with ESP8266 (01). I tried to follow a lot of online tutorial with no result.
In particular this one http://www.martyncurrey.com/arduino-to-esp8266-serial-commincation/. I think connections between Arduino Nano and ESP8266 are fine, when I upload the code on Arduino the red led on the ESP8266 turns on, I set the Arduino Monitor to 9600 BAUD and try to send command like "AT" but I got not reply from ESP8266. I also tried to switch to 115200 BAUD with no result too.
I don't if is something wrong or ESP8266 is damaged. Is there any tutorial that you may suggest?
