Error in sending AT commands in esp8266 connecting to arduino IDE I am working on esp8266 with Arduino. 

I have connected pins like arduino-esp 3.3-vcc
gnd-gnd 3.3-CH_PD RX-TX TX-RX  and reset to gnd using 3k resistor. 

I couldn't send AT commands in serial monitor in Arduino IDE. 

Later I connected a capacitor between Vcc and Gnd. Now I could send AT commands and I am getting same commands back. Whatever I entered, I am getting the same back.

I didn't get reply as OK. And I got some random characters too. Can anyone help me with this?
Looks like your connection is somewhere missing.

Connect CH_PD and reset pin to high--i.e. 3.3v.
