BluetoothHealth

Kotlin |Java

public final class BluetoothHealth
extends Object implements BluetoothProfile

java.lang.Object
↳	android.bluetooth.BluetoothHealth

This class was deprecated in API level 29.
Health Device Profile (HDP) and MCAP protocol are no longer used. New apps should use Bluetooth Low Energy based solutions such as BluetoothGatt, BluetoothAdapter.listenUsingL2capChannel(), or BluetoothDevice.createL2capChannel(int)

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 BluetoothAdapter#getProfileProxy 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)
