Topic: ESP8266 with arduino NO AT RESPONSE (Read 239 times) previous topic - next topic

Hi all,

I try to do a communication with the esp8266 and Arduino nano since few days, but nothing happens. I've tested many sketches, solution... I've used uart (0,1) from Arduino or SoftwareSerial on multiple I/O but not working.

I also use external voltage ...

When I send AT command directly in the serial monitor It work fine!

So why when I send AT command with the Arduino, the esp8266 doesn't send a response?

I'm total Lost...

NI$HANT

are u sending carriage return \r or \n ,tried? after your AT request.

No ... When I test

Serial.println("AT");

[Prints data to the serial port as human-readable ASCII text followed by a carriage return character (ASCII 13, or '\r') and a newline character (ASCII 10, or '\n').]

Serial Monitor doesn't return any ''ok''

Perhaps you missed to pass through the answer of the esp8266 to your serial monitor?

Could you give us your code?
