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..

A command ends with the PAIR of characters carriage return and line feed "\r\n". You might only be sending one of these when you press "enter". 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.

Thank you so much kolban for the reply. It actually helped.. The problem is solved by pressing "enter" then "cntrl+j". It works Hyperterminal as well as Putty.. Again thanks a lot..
