I'm new with the ESP8266. Today I bought one and found a tutorial to connect it in this way

ARDUINO WIRING

The wiring is made without the microprocessor of Arduino as you may see in the picture. When I connected it this way the Serial COM of the Arduino IDE, at 9600 baud sends this:

ö,2Yâ@ÈH
+ôÈLÃ<(ÔŒÐ�ÀÀŒŽ¡C¡¥µThinker Technology Co. Ltd.

invalid

and at 115200 baud this pops on

I really don't know whats going on, an it keeps rebooting or doing this repeatedly.
Any help would be very appreciated.

This way you doing (without the atmega328) and connecting rx-rx and tx-tx you are setting the ESP to be programmed or burn a new firmware. The messages are right to the ESP module with a standard firmware. Look this tutorial, instead of use a FTDI programmer your are using the arduino boart, pretty much the same.

  • But to the guy in the tutorial it worked pretty well, in my case i can put some AT commands that will work but have no effect on my problem(AT+RST//AT) – BREAKWAVE Apr 07 '17 at 23:44
  • probably are different firmwares. Its ok if you cant use the AT commands doesn't mean the ESP isn't working. – Fabio Henrique Fudoli Apr 08 '17 at 04:44
