- Thu Mar 02, 2017 12:49 pm #63242 Hello. I'm a newbie with the ESP8266 and I'm not getting any response from the board.
I'll explain the setup just in case you find something interesting:

I have the ESP-07 (16 pin variant) according to the wiki.

I have a 3.3 volts power supply made with the LM315 and I'm using a CP2102 USB 2.0 to TTL UART Module

The connections are the following:
CP2102-gnd -> gnd
ESP-RX -> CP2102-TX
ESP-TX -> CP2102-RX
ESP-RST -> 3.3v
ESP-EN(CH PD) -> 3.3v
ESP-GPIO0 -> gnd
ESP-GPIO2 -> 3.3v
ESP-GPIO15 -> gnd
VCC -> 3.3v

I'm also using Ubuntu Linux latest ver.
Using Arduino IDE. I did set the port and opened the Serial Monitor and set all the bauds possible while sending the "AT" comand, and also had the option of New Line and Carriage.

I have always a solid red on the LED on the ESP and CP2102 too.

Help please I have so many things I wanna do with this.

ESP-GPIO0 -> gnd

This is to get into Firmware Upload mode.
It should be at VCC to execute AT Firmware.
