user27391: When i Connected Rx>Rx (Rx Of module To Pin 0 Of Arduino) And Tx>Tx ( Tx Of Module To Pin 1 Of Arduino), The AT Command Test shows The Following error With Scrambled Words, but when I Connect Rx>Tx (Rx Of Module To Pin 1 Of Arduino) And Tx>Rx(Tx Of Module To Pin 0 Of The arduino), The AT Command Test Shows a Blank Screen. I Connected VCC, CHPD and RST Of Module to 3v Of Arduino and GND Of Module To GND Of Arduino. So How Do I Connect Arduino To Wifi Module which passes the at command test, Btw i Have an Intermediate, ie Motor Shield, I Connected Motor Sheild To Arduino And Then I connected Wifi Module To Motor Shield. Listen So  I need To Connect Wifi Module To Arduino, such that there isnt any error. what do i do?

user26986: The first connection you made between arduino and esp which resulted in some random data means both are communicating whereas the second connection where the screen shows blank means communication hasnt been established on account of incorrect wiring. So your first connection tx>tx and rx>rx is correct.
The only two area which you need to check is the baud rate and the mode of return. Some Esps work at 115200 with mode carriage return. So you can try different combinations of baud rate and mode to check which one does your Esp support.
