Recently, I working a project,which the arduino Uno get the data from RFID reader and use bluetooth to connect to the phone and let the phone play a music),but facing some problem,
First, I finished the RFID and arduino Uno part by this method

But I don't know what to do in next part(connect Bluetooth and phone), is there any example can let me follow or any of you have a suggestion?I am just a beginner, plz help!!! 
I use Bluetooth HC08, do i need to connect the EN pin to Arduino Uno?
and the PC or phone cant sense the HC08, do i need to do programme or somthing to active it??
The HC 08 and HC 05 are very similiar, so you should be able to follow tutorials for the latter.
