    Health Device Profile

    + +

    Android 4.0 (API level 14) introduces support for the Bluetooth Health Device +Profile (HDP). This lets you create applications that use Bluetooth to +communicate with health devices that support Bluetooth, such as heart-rate +monitors, blood meters, thermometers, and scales. The Bluetooth Health API +includes the classes {@link android.bluetooth.BluetoothHealth}, {@link +android.bluetooth.BluetoothHealthCallback}, and {@link +android.bluetooth.BluetoothHealthAppConfiguration}, which are described in The Basics.

    + +

    In using the Bluetooth Health API, it's helpful to understand these key HDP concepts:

    + + + + + + + + + + + + + + + + + + + + + + + + +
    ConceptDescription
    SourceA role defined in HDP. A source is a health device that +transmits medical data (weight scale, glucose meter, thermometer, etc.) to a +smart device such as an Android phone or tablet.
    SinkA role defined in HDP. In HDP, a sink is the smart device that +receives the medical data. In an Android HDP application, the sink is +represented by a {@link android.bluetooth.BluetoothHealthAppConfiguration} +object.
    RegistrationRefers to registering a sink for a particular health device.
    ConnectionRefers to opening a channel between a health device and a smart device +such as an Android phone or tablet.
    + +

    Creating an HDP Application

    + +

    Here are the basic steps involved in creating an Android HDP application:

    +
      + +
    1. Get a reference to the {@link android.bluetooth.BluetoothHealth} proxy +object.

      Similar to regular headset and A2DP profile devices, you must call +{@link android.bluetooth.BluetoothAdapter#getProfileProxy getProfileProxy()} +with a {@link android.bluetooth.BluetoothProfile.ServiceListener} and the {@link +android.bluetooth.BluetoothProfile.ServiceListener#HEALTH} profile type to +establish a connection with the profile proxy object.

      2. + +
    2. Create a {@link android.bluetooth.BluetoothHealthCallback} and register an +application configuration +({@link android.bluetooth.BluetoothHealthAppConfiguration}) +that acts as a health +sink.
      3. + +
    3. Establish a connection to a health device. Some devices will initiate the +connection. It is unnecessary to carry out this step for those devices.
      4. + +
    4. When connected successfully to a health device, read/write to the health +device using the file descriptor.

      The received data needs to be interpreted +using a health manager which implements the IEEE 11073-xxxxx +specifications.

      5. + +
    5. When done, close the health channel and unregister the application. The +channel also closes when there is extended inactivity.
      6. +
    + +
