This documentation describes different Bluetooth profiles and explains how to use the Bluetooth APIs to accomplish the four major tasks necessary to communicate using Bluetooth: Setting up Bluetooth.
Finding devices that are either paired or available in the local area. Connecting devices. Transferring data between devices. The basics For Bluetooth-enabled devices to transmit data between each other, they must first form a channel of communication using a pairing process. If Bluetooth is available, there are three steps to make a connection: Find nearby Bluetooth devices , either devices that are already paired or new ones. Connect to a Bluetooth device.
Transfer data with the connected device. The following are the classes and interfaces you need in order to create Bluetooth connections: BluetoothAdapter Represents the local Bluetooth adapter Bluetooth radio. The BluetoothAdapter is the entry-point for all Bluetooth interaction. Using this, you can discover other Bluetooth devices, query a list of bonded paired devices, instantiate a BluetoothDevice using a known MAC address, and create a BluetoothServerSocket to listen for communications from other devices.
BluetoothDevice Represents a remote Bluetooth device. Use this to request a connection with a remote device through a BluetoothSocket or query information about the device such as its name, address, class, and bonding state. This is the connection point that allows an app to exchange data with another Bluetooth device using InputStream and OutputStream. In order to connect two devices, one device must open a server socket with this class.
When a remote Bluetooth device makes a connection request to this device, the device accepts the connection and then returns a connected BluetoothSocket. BluetoothClass Describes the general characteristics and capabilities of a Bluetooth device. This is a read-only set of properties that defines the device's classes and services.
Although this information provides a useful hint regarding a device's type, the attributes of this class don't necessarily describe all Bluetooth profiles and services that the device supports. BluetoothProfile An interface that represents a Bluetooth profile.
A Bluetooth profile is a wireless interface specification for Bluetooth-based communication between devices. An example is the Hands-Free profile. For more discussion of profiles, see Bluetooth profiles. BluetoothHeadset Provides support for Bluetooth headsets to be used with mobile phones. This includes both the Bluetooth Headset profile and the Hands-Free v1.
BluetoothHealthAppConfiguration Represents an app configuration that the Bluetooth Health third-party app registers to communicate with a remote Bluetooth health device. Step 5: Enter PIN You'll be prompted for a pin which may will vary from stereo to stereo, but is usually and the pairing process will be complete.
Optional: Enable Media The entry in the Bluetooth devices list should read "Connected to phone and media audio. Step 6: Enjoy your music Select Bluetooth audio as the source on your car stereo.
And enjoy your mp3s as well as internet streaming radio services wirelessly over Bluetooth. More Galleries Toyota debuts halo Capstone trim for Tundra pickup.
