Can not connect with Bluetooth hc-05
It is very simple really.

Initially the Bluetooth got paired automatically with my Android, but apparently the variable transmission was not complete.

If this is the case with your module,it will be blinking with high frequency.

So here is what I did:


Hit the RESET button on HC-05 once
Go to Android Bluetooth Settings and UNPAIR HC-05
Now Pair it again by clicking on it
You will be prompted to enter password- '1234'
Open your Bluetooth Terminal and you will find your data appearing
on Android


P.S.-A 2 Hz blinking frequency on HC-05 should signify proper connection
