ESP8266 Community Forum

Hi

I am trying to work with ESP8266 S01 but it does not work.

Device is giving error messages, and I do not know that why it happened.
Can you help me?

My connections are as follows :

ESP VCC - 3.3V
ESP CHPD - 3.3V
ESP GND - GND
ESP RX - TX
ESP TX - RX

Thank you!

Maybe the device doesn't have the AT firmware loaded.

In that case TS wouldn't have a prompt and "ERROR"-messages like that.

@espnew: open a serial connection at 74880 baud and reset your ESP.
Have a look at the console and copy-paste the entire contents here on the forum (it should start with ets Jan 8 2013,rst cause:?, boot mode:(?,?), where ? are numbers).

I have tried your commands but it still doesn't work. I received these codes


And then I converted my connection of baudrate to 115200 and reset


Thank You !


Edit : This ESP worked a few days ago, I have tried new ESP S01 but the problem is continuing.
