BluetoothDevice

public final class BluetoothDevice
extends Object implements Parcelable

java.lang.Object
   ↳ android.bluetooth.BluetoothDevice


Represents a remote Bluetooth device. A BluetoothDevice lets you create a connection with the respective device or query information about it, such as the name, address, class, and bonding state.

This class is really just a thin wrapper for a Bluetooth hardware address. Objects of this class are immutable. Operations on this class are performed on the remote Bluetooth hardware address, using the BluetoothAdapter that was used to create this BluetoothDevice.

To get a BluetoothDevice, use BluetoothAdapter.getRemoteDevice(String) to create one representing a device of a known MAC address (which you can get through device discovery with BluetoothAdapter) or get one from the set of bonded devices returned by BluetoothAdapter.getBondedDevices(). You can then open a BluetoothSocket for communication with the remote device, using createRfcommSocketToServiceRecord(UUID).

Note: Requires the BLUETOOTH permission.

autoConnect boolean: Whether to directly connect to the remote device (false) or to automatically connect as soon as the remote device becomes available (true).
callback BluetoothGattCallback: GATT callback handler that will receive asynchronous callbacks.
Returns
BluetoothGatt
Throws
IllegalArgumentException if callback is null

connectGatt

Added in API level 23
BluetoothGatt connectGatt (Context context, 
                boolean autoConnect, 
                BluetoothGattCallback callback, 
                int transport)

Connect to GATT Server hosted by this device. Caller acts as GATT client. The callback is used to deliver results to Caller, such as connection status as well as any further GATT client operations. The method returns a BluetoothGatt instance. You can use BluetoothGatt to conduct GATT client operations.

Parameters

transport int: preferred transport for GATT connections to remote dual-mode devices TRANSPORT_AUTO or TRANSPORT_BREDR or TRANSPORT_LE
Returns
BluetoothGatt
Throws
IllegalArgumentException if callback is null

createBond

Added in API level 19
boolean createBond ()

Start the bonding (pairing) process with the remote device.

This is an asynchronous call, it will return immediately. Register for ACTION_BOND_STATE_CHANGED intents to be notified when the bonding process completes, and its result.

Android system services will handle the necessary user interactions to confirm and complete the bonding process.

Requires BLUETOOTH_ADMIN.

Returns
boolean false on immediate error, true if bonding will begin

createInsecureRfcommSocketToServiceRecord

Added in API level 10
BluetoothSocket createInsecureRfcommSocketToServiceRecord (UUID uuid)

Create an RFCOMM BluetoothSocket socket ready to start an insecure outgoing connection to this remote device using SDP lookup of uuid.

The communication channel will not have an authenticated link key i.e it will be subject to man-in-the-middle attacks. For Bluetooth 2.1 devices, the link key will be encrypted, as encryption is mandatory. For legacy devices (pre Bluetooth 2.1 devices) the link key will be not be encrypted. Use createRfcommSocketToServiceRecord(UUID) if an encrypted and authenticated communication channel is desired.

This is designed to be used with listenUsingInsecureRfcommWithServiceRecord(String, UUID) for peer-peer Bluetooth applications.

Use connect() to initiate the outgoing connection. This will also perform an SDP lookup of the given uuid to determine which channel to connect to.

The remote device will be authenticated and communication on this socket will be encrypted.

Hint: If you are connecting to a Bluetooth serial board then try using the well-known SPP UUID 00001101-0000-1000-8000-00805F9B34FB. However if you are connecting to an Android peer then please generate your own unique UUID.

Requires BLUETOOTH

Parameters
uuid UUID: service record uuid to lookup RFCOMM channel
Returns
BluetoothSocket a RFCOMM BluetoothServerSocket ready for an outgoing connection
Throws
IOException on error, for example Bluetooth not available, or insufficient permissions

createRfcommSocketToServiceRecord

Added in API level 5
BluetoothSocket createRfcommSocketToServiceRecord (UUID uuid)

Create an RFCOMM BluetoothSocket ready to start a secure outgoing connection to this remote device using SDP lookup of uuid.

This is designed to be used with listenUsingRfcommWithServiceRecord(String, UUID) for peer-peer Bluetooth applications.

Use connect() to initiate the outgoing connection. This will also perform an SDP lookup of the given uuid to determine which channel to connect to.

The remote device will be authenticated and communication on this socket will be encrypted.

Use this socket only if an authenticated socket link is possible. Authentication refers to the authentication of the link key to prevent man-in-the-middle type of attacks. For example, for Bluetooth 2.1 devices, if any of the devices does not have an input and output capability or just has the ability to display a numeric key, a secure socket connection is not possible. In such a case, use {#link createInsecureRfcommSocketToServiceRecord}. For more details, refer to the Security Model section 5.2 (vol 3) of Bluetooth Core Specification version 2.1 + EDR.

Hint: If you are connecting to a Bluetooth serial board then try using the well-known SPP UUID 00001101-0000-1000-8000-00805F9B34FB. However if you are connecting to an Android peer then please generate your own unique UUID.

Requires BLUETOOTH

Parameters
uuid UUID: service record uuid to lookup RFCOMM channel
Returns
BluetoothSocket a RFCOMM BluetoothServerSocket ready for an outgoing connection
Throws
IOException on error, for example Bluetooth not available, or insufficient permissions

describeContents

Added in API level 5
int describeContents ()

Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. For example, if the object will include a file descriptor in the output of writeToParcel(Parcel, int), the return value of this method must include the CONTENTS_FILE_DESCRIPTOR bit.

Returns
int a bitmask indicating the set of special object types marshaled by this Parcelable object instance.

equals

Added in API level 5
boolean equals (Object o)

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

  • It is reflexive: for any non-null reference value x, x.equals(x) should return true.
  • It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
  • It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
  • It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
  • For any non-null reference value x, x.equals(null) should return false.

The equals method for class Object implements the most discriminating possible equivalence relation on objects; that is, for any non-null reference values x and y, this method returns true if and only if x and y refer to the same object (x == y has the value true).

Note that it is generally necessary to override the hashCode method whenever this method is overridden, so as to maintain the general contract for the hashCode method, which states that equal objects must have equal hash codes.

Parameters
o Object: the reference object with which to compare.
Returns
boolean true if this object is the same as the obj argument; false otherwise.

fetchUuidsWithSdp

Added in API level 15
boolean fetchUuidsWithSdp ()

Perform a service discovery on the remote device to get the UUIDs supported.

This API is asynchronous and ACTION_UUID intent is sent, with the UUIDs supported by the remote end. If there is an error in getting the SDP records or if the process takes a long time, ACTION_UUID intent is sent with the UUIDs that is currently present in the cache. Clients should use the getUuids() to get UUIDs if service discovery is not to be performed.

Requires BLUETOOTH.

Returns
boolean False if the sanity check fails, True if the process of initiating an ACL connection to the remote device was started.

getAddress

Added in API level 5
String getAddress ()

Returns the hardware address of this BluetoothDevice.

For example, "00:11:22:AA:BB:CC".

Returns
String Bluetooth hardware address as string

getBluetoothClass

Added in API level 5
BluetoothClass getBluetoothClass ()

Get the Bluetooth class of the remote device.

Requires BLUETOOTH.

Returns
BluetoothClass Bluetooth class object, or null on error

getBondState

Added in API level 5
int getBondState ()

Get the bond state of the remote device.

Possible values for the bond state are: BOND_NONE, BOND_BONDING, BOND_BONDED.

Requires BLUETOOTH.

Returns
int the bond state

getName

Added in API level 5
String getName ()

Get the friendly Bluetooth name of the remote device.

The local adapter will automatically retrieve remote names when performing a device scan, and will cache them. This method just returns the name for this device from the cache.

Requires BLUETOOTH

Returns
String the Bluetooth name, or null if there was a problem.

getType

Added in API level 18
int getType ()

Get the Bluetooth device type of the remote device.

Requires BLUETOOTH

Returns
int the device type DEVICE_TYPE_CLASSIC, DEVICE_TYPE_LE DEVICE_TYPE_DUAL. DEVICE_TYPE_UNKNOWN if it's not available

getUuids

Added in API level 15
ParcelUuid[] getUuids ()

Returns the supported features (UUIDs) of the remote device.

This method does not start a service discovery procedure to retrieve the UUIDs from the remote device. Instead, the local cached copy of the service UUIDs are returned.

Use fetchUuidsWithSdp() if fresh UUIDs are desired.

Requires BLUETOOTH.

Returns
ParcelUuid[] the supported features (UUIDs) of the remote device, or null on error

hashCode

Added in API level 5
int hashCode ()

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by HashMap.

The general contract of hashCode is:

  • Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
  • If two objects are equal according to the equals(Object) method, then calling the hashCode method on each of the two objects must produce the same integer result.
  • It is not required that if two objects are unequal according to the equals(java.lang.Object) method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the JavaTM programming language.)

Returns
int a hash code value for this object.

setPairingConfirmation

Added in API level 19
boolean setPairingConfirmation (boolean confirm)

Confirm passkey for PAIRING_VARIANT_PASSKEY_CONFIRMATION pairing.

Requires BLUETOOTH_ADMIN.

Parameters
confirm boolean
Returns
boolean true confirmation has been sent out false for error

boolean setPin (byte[] pin)

Set the pin during pairing when the pairing method is PAIRING_VARIANT_PIN

Requires BLUETOOTH_ADMIN.

Parameters
pin byte
Returns
boolean true pin has been set false for error

toString

Added in API level 5
String toString ()

Returns a string representation of this BluetoothDevice.

Currently this is the Bluetooth hardware address, for example "00:11:22:AA:BB:CC". However, you should always use getAddress() if you explicitly require the Bluetooth hardware address in case the toString() representation changes in the future.

Returns
String string representation of this BluetoothDevice

writeToParcel

Added in API level 5
void writeToParcel (Parcel out, 
                int flags)

Flatten this object in to a Parcel.

Parameters
out Parcel: The Parcel in which the object should be written.
flags int: Additional flags about how the object should be written. May be 0 or PARCELABLE_WRITE_RETURN_VALUE.
