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
//some garbage values//

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.
