- Fri Feb 17, 2017 2:08 am #62682 I use Arduino UNO to connect to ESP8266
Arduion D10/11 --> ESP8266 RX/TX
Arduino V3.3 --> ESP8266 VCC/CH_PD
Arduino GND --> ESP8266 GND
ESP8266 GPIO0 GPIO 2 and RST are float

I use Arduino software serial to communicate with ESP8266
and use Arduino serial to communicate with serial monitor port
The baud rate is 115200

As shown the figure above, I gave command "AT" in serial monitor port and get "OK" response from ESP8266. But the following commands got not good response.
These responses seems missing something or lose some character?
I had tried to use external 3.3V DC power but get no difference

Any suggestion?

Perhaps you can copy/paste the text of the commands and responses.
