An Android phone user has purchased a new Bluetooth headset for phone calls. He has reported that his phone does not support the headset. Both devices are turned on and seem to be working. What is the problem here?

The Bluetooth devices must be paired in order to function if they have never been used together before. Usually, pairing is an easy process. The following are the CompTIA A+ procedure for connecting Bluetooth devices:
1. Enable Bluetooth.
2. Enable pairing.
3. Find a device for pairing.
4. Enter the appropriate PIN code.
5. Test connectivity.
