I have received an ESP8266 (ESP-07) Wi-Fi module from DealExtreme (Link: http://bit.ly/2dFJdxE).
It is a 4-pin module with the following pins: RX, TX, VCC and GND. The module has a switch so you can switch between the following modes: Program & UART. The module also has a RESET-button.
Here's a picture of my module:

I've connected the module to my Arduino Uno like this:
RX > RX,
TX > TX(TX>RX & RX > TX, like mentioned in manuals, results in no connection),
VCC > 3.3v (not using any level shifters because the module has on board level shifters),
GND > GND.

SomeA strange thing is when I open the serial monitor in the Arduino IDE after that moment (without resetting the module/unplug from 3.3v or change to UART mode), it keeps printing the following at 115200 BAUD:

Who know'sknows how to fix this problem so I can send AT commands to the module through the serial monitor in the Arduino IDE.
Thanks in regards (this is my first post so if some things are unclear, please let me know)

Edit: Note that I have to disconnect and reconnect the 3.3v to the module EVERY time to successfully run a command (like write_flash, flash_id et cetera).
Also tried connecting it to 5v and using an external power supply next to the USB.

Used 5v @ vcc and tried using external power supply next to USB

Change image size, made an edit earlier to note that I have to reconnect 3.3v before command
