HC-05 Module Returning Garbage Values With Arduino Uno LED Test Android App

If you are sending from the HC05 to the Uno, the RX should flash on the Uno, not TX. You have pin 4 of the Uno going to TX on the HC05 and pin 7 of the Uno going to the voltage divider and HC05 RX? Are you sure that the baud rate setting on the HC05 is 9600?

I just tried the code that I posted with my Andriod tablet and Bluetooth Terminal and it works fine (to Uno and HC05). I don't know what the problem is on your end.
