Usb Bluetooth Dongle Android 4

The Android platform includes support for theBluetooth network stack. TheBluetooth network stack allows a device to wirelessly exchange data with otherBluetooth devices. The application framework provides access to Bluetoothfunctionality through the Android BluetoothAPIs.

Android Things extends these APIs to enable apps to control the Bluetooth systemsettings, device pairing, and connection process.

Adding the required permissions

In addition to the BLUETOOTH and BLUETOOTH_ADMIN permissions, add the following toyour app's manifest file to use the Bluetooth connection and pairing APIs:

Note: See the Bluetooth sampleson GitHub.

Configuring device attributes

The Android Things Bluetooth APIs enable you to control the device class andsupported profiles exposed by the local Bluetooth adapter. To configure theBluetooth Class of Device(CoD),create a BluetoothClass instance via theBluetoothClassFactoryand set it using theBluetoothConfigManager:

I/O capabilities

Use BluetoothConfigManagerto report the Input/Output capabilities of your device to the Bluetooth service.Set the I/O capabilities for Bluetooth withsetIoCapability()and Bluetooth Low Energy (LE) withsetLeIoCapability()These methods accept one of the following values:

  • IO_CAPABILITY_NONE: Device has no input or output capabilities.This is the default value.
  • IO_CAPABILITY_OUT: Device has a display only.
  • IO_CAPABILITY_IN: Device can accept keyboard user input only.
  • IO_CAPABILITY_IO: Device has a display and can accept basic (yes/no) input.
  • IO_CAPABILITY_KBDISP: Device has a display and can accept keyboard user input.

The I/O capabilities of the device are shared with remote devices during thePairing Feature Exchangephase of device pairing. The Bluetooth service determineswhich pairing variants your device can support based on its I/O capabilities.

Warning: Currently Android Things devices reporting IO_CAPABILITY_IN orIO_CAPABILITY_KBDISP are not capable of pairing with a remote device thatalso reports IO_CAPABILITY_KBDISP, such as an Android mobile device.

Enabled profiles

To configure the enabled Bluetooth profiles on the local device, use theBluetoothProfileManager.EachBluetoothProfilemust be enabled before a remote device can connect to it. Query the current setof enabled profiles withgetEnabledProfiles()and update them using one of the following methods:enableProfiles()ordisableProfiles():

Note: Each profile change restarts the Bluetooth service. If you need to enableand disable profiles at the same time, useenableAndDisableProfiles()to commit both changes at once. You can monitor restarts of the Bluetoothservice with the ACTION_STATE_CHANGEDbroadcast.

Pairing with a remote device

See Finding Devicesin the Android Bluetooth Guide for more details on discovering remote devicesand determining if they are already bonded with the local device. If the remotedevice is already bonded, you can jump directly to connecting to a remotedevice.

To begin the pairing process with a remote device:

  1. Register aBluetoothPairingCallbackwith theBluetoothConnectionManager
  2. CallinitiatePairing()with the discovered peer device. For peer devices which report theirInput/Output Capability as IO_CAPABILITY_NONE, you will receive a callback inonPaired(),once pairing is complete.
  3. If the peer device requires user input to pair, handle thepairing request inonPairingInitiated().

ThePairingParamsprovided to the callback defines the Bluetooth pairing variant required by theremote device. These represent different pairing security schemes, and your appis responsible for taking the appropriate action as documented for each variant.For pairing variants that require user input, complete the process by callingfinishPairing().

Note: Your device must report the appropriate I/O capabilities to successfullypair using variants that require input and/or output.

Connecting to a remote device

Once you have successfully paired over Bluetooth, your app can connect toprofiles and services on the remote device. The Android Bluetooth API exposesconnection features for a restricted set of device profiles. See ConnectingDevices in theAndroid Bluetooth Guide and the Bluetooth Low EnergyGuide for more details onconnecting to devices using the RFCOMM and GATT profiles.

The Android ThingsBluetoothConnectionManagerenables apps to connect to additional profiles and services on remote devices.Use thegetConnectableProfiles()method to report the available profiles on the remote device.

To connect with a specific profile on a given BluetoothDevice:

  1. Register aBluetoothConnectionCallbackwith theBluetoothConnectionManager
  2. Initiate the connection with theconnect()method, providing the device and the targetBluetoothProfile
  3. Handle the connection request inonConnectionRequested()

TheConnectionParamsprovided to the callback include additional details about the type of connectionrequested. Inspect those parameters in your code, and then determine whether toaccept or reject the request withconfirmOrDenyConnection():
