ESP8266-01 not responding to AT commands

my esp8266-01 is not responding to AT commands when i upload a blink sketch. I have to re flash it with some other firmware which i got from the internet to make the AT commands work i am new in ESP modules ...so is it common or have i done anything wrong the connections are shown below while flashing.. i used an arduino uno for flashing

TX-TX

RX-RX

VCC- 3.3v external supply

CH_PD-VCC(The CH_PD pin in my module was named as "EN")

RST-VCC

GPIO0-GND

GND-GND

the blink sketch in the example is working fine but not responding to AT commands while blinking...

this is what the serial monitor outputs at 115200 NL&CR

You need to flash the ESP8266 with the AT firmware in-order to use the AT Commands. Download The AT firmware and flash it using esptool.py or NodeMCU flasher.
