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?
You also need to convert the 5v to 3.3v on the RX line.

- you connected what to what? This is very unclear. Please edit your question and clarify what you have done. Also try to write proper English if possible. Sentences start with a capital letter.
