Micro controller programming with bluetooth dongle
The dongle you mentioned has a USB interface. PIC 16F628a doesn't have one. So they can't directly communicate with each other.

Better idea will be to use a serial based bluetooth module like HC-05.



You can communicate with this modules using serial Tx and Rx. However if you want to use same Tx Rx for uploading code to your micro controller, then you might have to implement software serial on two other pins in order to communicate with the bluetooth.

Search for online arduino tutorials for bluetooth module. You will find a lot. You can implement those with your PIC.
