I've not had any problem with my ESP8266.
But today, it is not working well.
It's supposed to return AT commands on the serial monitor but, it returns only one character per every receive.

- Mon Jun 08, 2015 5:29 pm #19876 Looks like you don't have it in the correct baudrate. I think it defaults to 9600 on boot, but my Arduino is configured for 115200. You can check your settings on the Arduino IDE as well.

- Tue Jun 09, 2015 12:15 am #19896 I checked the baudrate but, it is still not working.
Is my module broken? I connected TX pin from arduino to RX of esp8266 with a 1K and a 2K resistors.
I think the other pins are connected correctly.

- Thu Jun 11, 2015 11:51 pm #20227 which pins are exactly connected?
Do you use the resistors as a voltage divider? The ESP8266 pins are not 5v tolerant! 5V can destroy the Chip?
Please post your code!
