Here is what I am doing
Arduino(UNO)--------Esp8266 3.3 v -- vcc TX -- RX RX -- TX 3.3 v -- EN(ch_pd) GND -- GND
there is no blinking of LED on Esp8266, sometimes the LED is on and sometimes it is not. And when I send "AT" command using Serial of Arduino IDE, only RX light of Arduino blinks, TX is not blinking and there is no response of that command. I am having 3.3 voltage on my Vcc pin of Esp8266 but the voltage on the TX and RX pins of Esp8266 is 5 volts, I know that i can reduce this to 3.3 voltage by using a voltage regulator but my question is why there is no blinking on the module even when i have supplied the proper 3.3 voltage and GND? What's the difference between the blinking and a still LED on Esp8266? I have tried every tutorial on internet. No help at all. Right now I am so exhausted that I want to quit.If you can help in solving the problem, I would be very thankful to you sir.
