In Android, several commonly used Bluetooth profiles are: spp (Serial Port profile), a2dp (Advanced Audio distribution profile), and avrcp (audio/video remote control profile), hid (Human Interface Device profile), HFP (hands-free profile ). Among them, media is highly correlated with a2dp and avrcp, which is often used for data communication.Concept of Bluetooth Profile Profile defines a Bluetooth-based application. Each profile specification mainly
