I am very much new in 8266.
My 8266 ESP-07 board arrived yesterday and I am trying to get it working.

I have Arduino IDE version 1.6.6
Boards used: ARDUINO UNO(Atmega328p) and ESP-07

Board interconnections done as follows
ARDUINO ESP-07
--------------- -----------------
Tx -- Tx
Rx -- Rx

ESP-07 connections as follows
Vcc -- +3v
Gnd -- gnd
GPIO 0 -- open
GPIO 2 -- open
GPIO 15 -- GND
EN(CH_PD) -- +3.3v

Serial monitor set to BAUD 115200 NL & CR
BLINK program uploaded on ARDUINO UNO

Now when I power up,

red light on esp-07 lights up.
Now I momentarily connect RST pin of esp-07 to GND I get following in my Serial monitor window
