BluetoothHealth

public final class BluetoothHealth
extends Object implements BluetoothProfile

java.lang.Object
   ↳ android.bluetooth.BluetoothHealth


Public API for Bluetooth Health Profile.

BluetoothHealth is a proxy object for controlling the Bluetooth Service via IPC.

How to connect to a health device which is acting in the source role.

  • Use getProfileProxy(Context, BluetoothProfile.ServiceListener, int) to get the BluetoothHealth proxy object.
  • Create an BluetoothHealth callback and call registerSinkAppConfiguration(String, int, BluetoothHealthCallback) to register an application configuration
  • Pair with the remote device. This currently needs to be done manually from Bluetooth Settings
  • Connect to a health device using connectChannelToSource(BluetoothDevice, BluetoothHealthAppConfiguration). Some devices will connect the channel automatically. The BluetoothHealth callback will inform the application of channel state change.
  • Use the file descriptor provided with a connected channel to read and write data to the health channel.
  • The received data needs to be interpreted using a health manager which implements the IEEE 11073-xxxxx specifications.
  • When done, close the health channel by calling disconnectChannel(BluetoothDevice, BluetoothHealthAppConfiguration, int) and unregister the application configuration calling unregisterAppConfiguration(BluetoothHealthAppConfiguration)
