More specifically, the problem that the car machine can transmit music control instructions (besides music playing related control, operations such as music collection and playlist switching), music information, music lists and other data while playing music only through Bluetooth connection is solved, and information customized by a third party (for example, information such as application Logo) can be transmitted by combining a third party music App. In the scheme, the vehicle machine and the mobile phone establish a music playing channel and simultaneously establish an SPP channel, and the vehicle machine and the mobile phone side perform efficient communication according to a customized protocol based on the channel, on the premise of not influencing normal music playing, perform command receiving and sending such as music control (including playing, pausing, next music collection) and the like, switch a music playing list, send customized information and the like. The problem of when car machine bluetooth broadcast music, car machine control cell-phone music broadcast function singleness is solved, except broadcast control, can also switch the playlist, collect operations such as music.
The bluetooth Serial Port is a device which is based on the SPP protocol (Serial Port profile) and can create a Serial Port between bluetooth devices for data transmission. The purpose of a bluetooth serial port is to guarantee a complete communication path between applications on two different devices (both ends of the communication). For example, between the Bluetooth module (BF10-A) and BF10-A, between the Bluetooth module and the Bluetooth adapter, and between the Bluetooth module and the PDA Bluetooth, the Bluetooth serial port data transmission can be established through SPP Bluetooth serial port service. The purpose of the bluetooth module (BF10-a) is to guarantee a complete communication path between applications on two different devices (both ends of the communication) and to maintain a communication segment between them. An application does not only mean an end-user application, but may also be a higher layer protocol or other service as an end-user application, for example. The bluetooth module (BF10-a) is ready to cover applications communicating with the device serial port. In one simple configuration example, the communication segment is a BT direct link between devices. If the communication segment is another network, the BT is used to establish a path between the device and a network access device (e.g., Modem). The bluetooth module (BF10-a) is only directed to the connection between directly interconnected devices, or the interconnection between a device and a network access device. The bluetooth module (BF10-a) supports other configurations, such as BT communication at one end and a wired interface at the other end, as shown in the second figure below. These devices are not just modems, but provide simple services. The two-end communication device must be compatible with the protocol of the Bluetooth module BF 10-A. The first type of device is a communication terminal device such as a computer, a printer, etc. The second type of device is part of the communications segment, such as a Modem. However, in order to simplify the protocol content, the bluetooth module (BF10-a) protocol does not distinguish between the two devices. Both types of devices are also supported for the transfer of information between the two bluetooth module BF10-a entities, some of which are intended only for the second type of devices. Nor is there a strict division of the information used by the two classes of devices in the protocol. But the user decides which information to use. Since one device does not know the type of other devices on the communication path, each device should send all available information as specified by the protocol. Replacing a serial port line: i use 2 BF10-A bluetooth modules, one is used as a main module + MAX3232(TTL changes to RS232 level chip), and the other is used as a slave module + MAX3232(TTL changes to RS232 level chip), and the corresponding Baud rate is set. The two modules are respectively connected to a PC machine through a DB9 interface. Data transmission can be carried out between the two PC computers through a serial port debugging tool. And the existing Bluetooth adapter forms Bluetooth serial port connection: i adopt a bluetooth adapter to connect the computer, use IVT bluetooth drive, a bluetooth module BF10-A is connected to my singlechip embedded system as the slave module. Using BF10-A, IVT Bluetooth driver software finds BF10-A Bluetooth module, connects and creates serial port reset. At the moment, serial port communication can be carried out between the serial port tool and the single chip microcomputer.
Some characteristics and applications of the SPP bluetooth protocol are for example:
1. how to acquire the bluetooth device to which the current handset has been bound?
// acquire default Bluetooth adapter
BluetoothAdapter mBtAdapter＝BluetoothAdapter.getDefaultAdapter()；
// obtaining currently available Bluetooth settings
Set<BluetoothDevice>pairedDevices＝mBtAdapter.getBondedDevices()；
After the current Bluetooth device is obtained, the paired Bluetooth devices of the current mobile phone can be obtained by traversing the pair devices.
2. How to scan for available bluetooth devices nearby?

The Android mobile phone is generally actively connected with the SPP protocol device (connected with a digital sensor of a bluetooth module) in a role of a client, and the connection process is as follows:
1. registering BroadcastReceiver by using a register receiver to acquire messages such as a Bluetooth state, search equipment and the like;
2. search using BlueAdatper;
3. obtaining the searched Bluetooth device information (such as name, MAC, RSSI) in onReceive () of BroadcastReceiver;
4. establishing a Bluetooth device object through the MAC address of the device;
5. deriving a Bluetooth SOCKET from the Bluetooth device, and preparing a SOCKET to read and write the device;
6. selecting connected protocol/service by the createRfcommsocketToServiceRecord () method of Bluetooth socket, wherein SPP (UUID: 00001101-;
after Connect (if not already paired, the system prompts automatically), the bluetooth device is read and written using getInputStream () and getOutputStream () of bluetooth socket.
-A2 DP is named after Advanced Audio Distribution Profile Bluetooth Audio Transmission model protocol. A2DP is a device capable of stacking data using a chip in a headphone to achieve high definition of sound. However, the headset supporting A2DP is not a bluetooth stereo headset, and the basic requirement for stereo implementation is two channels, so that a mono bluetooth headset cannot implement stereo. The sound can reach 44.1kHz, and the common earphone can only reach 8 kHz. If the handset supports bluetooth, the A2DP headset can be used as long as the A2DP protocol is loaded. Also, consumers see technical parameters referring to bluetooth V1.0V1.1V1.2V2.0-these refer to the technical version of bluetooth, which refers to the speed of transmission over bluetooth, whether they support A2DP and specifically whether the manufacturer of the bluetooth product uses this technology. A2DP defines transmitting high quality audio, mono or stereo, etc., over an ACL (asynchronous connection free) channel. A2DP function, protocol and procedure for frequency information. A2DP is determined by GAP (Generic Access Profile common Access protocol) and GAVDP (Generic Audio/Video Distribution Profile common Audio Video Distribution protocol), the latter defines the procedures required for the establishment of audio, Video streams, etc. A2DP defines the parameters and procedures required for the establishment of audio and Video streams. Inputting #1234# to the mobile phone, displaying A2DP PTS mode to start A2DP, and inputting again to turn off the function. The Bluetooth stereo headset + the mobile phone, and the Bluetooth stereo headset + the mobile phone have the greatest characteristic of being capable of listening to music played in the mobile phone directly through the Bluetooth stereo headset besides having a common voice call function. Currently, there are four smart phones with built-in A2DP mode in the market, including HP h6315(6365), motorola e680i, blackberry 9500 and HTC G11 inclusive S smart phones, which can directly listen to Music in the smart phones after being matched with bluetooth stereo headphones (e.g., i.tech. Clip. S35, i.tech Clip Music 801, i.tech Clip Music802, i.tech Clip D Radio, SolarVoice 908, Music band 807, etc.). In addition to the built-in A2DP, the mobile phone using Symbain Series 60 operating system, such as Nokia S60 mobile phone such as Nokia 7610, 6670, 3230, 6680, 6630, N-Gage, QD and so on, and Panasonic X700, X800. With the popularization of bluetooth devices, more and more people and notebook computers are also beginning to be built with bluetooth devices. The bluetooth application on the computer end can be of the most types, and can be performed through the bluetooth device no matter the connection of a printer, a mouse and a keyboard, or even the synchronization of a PDA and a mobile phone. At present, the most Hot application on a personal computer belongs to a Bluetooth earphone for speaking Skype, and the Bluetooth can be paired for use only by installing a Bluetooth receiver on the computer and installing a driver, so that the trouble of complicated wired device lines is solved. After the bluetooth stereo headset is pushed out, except that the bluetooth stereo headset can be used for carrying out Skype conversation, the headset can also be used for listening to music in a computer, no matter whether the specification of a bluetooth receiver in the computer is 1.1 version or 1.2 version, the stereo sound effect output provided by the bluetooth headset can be supported only after a driver supporting an A2DP mode is updated (WIDCOMM needs to be supported by more than 4.0 version, IVT needs to be supported by more than 1.4 version), so that a user can experience the feeling that ' sound ' is adjacent to the user's environment, and the user does not need to worry that a loudspeaker can interfere with other people. Bluetooth stereo headset + music player, if your cell-phone does not support bluetooth A2DP, but you want to listen to the music with the bluetooth headset again, also some manufacturers have launched HiFi (high fidelity) bluetooth transmission device (Blue Con35) suitable for 3.5mm headset plug. As long as there is a music Player with 3.5mm earphone joint, such as iPod, MP3Player, household stereo or radio, it can be directly converted into Bluetooth wireless transmission device, and it will be paired by itself only after the power supply of the transmitting end and the Bluetooth stereo earphone is turned on. A2DP (Advanced Audio Distribution Profile) is an Audio transmission protocol for bluetooth, and a typical application is bluetooth headphones. The audio data of the A2DP protocol is transmitted over the ACL Link, which is to be distinguished from the voice data transmitted over the SCO. A2DP does not include a remote control function, which refers to the protocol AVRCP. AVDTP defines the parameter negotiation, setup and transport procedures and the form of the exchanged signaling entities of the data stream handles between Bluetooth devices, which is the basic protocol of the A2DP framework. GAVDP defines two roles:
initiator (INT) -This device that is a signaling process [ initiating signaling ]
Acceptor (ACP) -This device that short response to an incomingrequest from the INT. [ responsive to signaling ]
A2DP realizes the following roles:
source (SRC) -A device is the SRC, an act as a source of a digital stream that is delayed to the SNK of the control
Sink (SNK) -A device is the SNK world bits as a sink of a digital stream delayed from the SRC on the same sink
Here, it should be noted that: generally, the roles of Source and Sink in A2DP are fixed, while the roles of GAVDP are interchangeable, and the initiator is the party that initiates signaling.
-limitations of the A2DP protocol
(1) Synchronized point-to-multipoint distribution is not supported.
(2) There are delays at the Source and Sink terminals.
(3) The rate of audio data must be sufficiently less than the transmission rate of bluetooth.
(4) Method of not providing any data protection
In the packaging of the first part of the data, it can be seen that a mediapackart header is added to each Media payload. The device mainly comprises the following parts:
timestamp (TS), Payload Type (PT), marker (M) bit [ set to all 0 ], extension (X) bit [ unused, set to all 0 ]. Specifically defined in the AVDTP protocol and not detailed here.
