- Thu Jun 25, 2015 10:22 am #21624 Hello everyone!! I am new to ESP-01. I am having this problem with ESP_01 module. I am using ESP-01 module with CP-2102 USART to USB chip. I successfully get the ready message on resetting the ESP-01 but on typing any command, I don't get any reply on the screen. Instead the command remains on screen and the cursor moves to start of line.

The ready message reads as :

"[Vendor:www.ai-thinker.com Version:0.9.2.4]

ready"

On typing any command and pressing enter:

"[Vendor:www.ai-thinker.com Version:0.9.2.4]

ready
AT"

(the cursor is actually at 'A' of 'AT")

Same goes for any other command


The TX and RX lights on the CP-2102 blink along with the blue light on the ESP-01 whenever I type anything. I am using a LM1117 3v3 for powering the ESP-01 which itself is powered by a 10V SMPS AC-DC adaptor. I tried using Hyperterminal as well as Putty programs but with same result. The baud settings are:

BPS: 9600
Data bits: 8
Parity: none
Stop Bits: 1
Flow control: none

Please help!!! Thanks in advance..

See if the settings of your terminal emulator provide for setting the effect of pressing enter. You might also get away with hand-entering the control codes. For example, on PuTTY, I believe CTRL+J will send a CR and enter will be the LF.
