ESP8266 Community Forum

- Thu Mar 03, 2016 9:31 am #42314 I just posted an ESP8266 off of ebay.com and have not been able to successfully interact with it. I'm connecting through a known working USB to TTL converter. I'm using a separate 3.3v power supply to provide power since the USB to TTL converter won't show up when trying to provide all power to the ESP8266.

Pins Connected as Follows
------------------------------------------------
VCC (ESP8266) -> 3.3v (Pwr Supp)
RST (ESP8266) -> 3.3v (Pwr Supp)
CH_PD (ESP8266) -> 3.3v (Pwr Supp)
TX (ESP8266) -> RX (USB2TTL)
RX (ESP8266) -> TX (USB2TTL)
GND (ESP8266) -> GND (USB2TTL)
GND (Pwr Supp) -> GND (USB2TTL)

LED Status
--------------
ESP8266 - Red Solid, Blue Flashes with Commands Entered in Terminal
USB2TTL - Red Solid
Pwr Supp - Green Solid

Software & Configuration
-------------
Using PuTTY to COM7 (USB2TTL)
Baud: 115200 (Tried 57600 & 9600)
Data Bits: 8
Stop Bits: 1

Power On Screenshot
I can see text when I power on the device, but some of it is garbled.

When I try to enter an AT command, it allows me to type it and send it. The blue light flashes on the ESP8266 for each key I press as well as enter. However, nothing happens.

Anyone know what I'm doing wrong?
