Connects to a remote device.

Namespace: wclBluetooth
Delphi
public
 function Connect(const Address: Int64; const Service: TGUID;
 const Channel: Byte = 0; const Authentication: Boolean = True;
 const Encryption: Boolean = False;
 const Timeout: Cardinal = 10000): Integer;

Parameters

Address
Type: Int64

The remote Bluetooth device address.

Service
Type: TGUID

The Bluetooth Service UUID. If the Channel parameter is zero, the system attempts to use Service to resolve the remote channel corresponding to the service. The service class is a normalized 128-bit GUID, defined by the Bluetooth specification. Common GUIDs are defined by the Bluetooth Assigned Numbers document. Alternatively, a unique GUID may be used for a domain-specific application.

Channel
Type: Byte

The RFCOMM channel number. If zero the Service UUID will be used.

Authentication
Type: Boolean

Specifies that authentication is required for a connect operation to complete successfully. Setting this option actively initiates authentication during connection establishment, if the two Bluetooth devices were not previously authenticated.

Encryption
Type: Boolean

The option enforces encryption to establish a connection. Encryption is only available for authenticated connections.

Timeout
Type: Cardinal

The connect timeout in milliseconds. The default value is 10000 milliseconds.

Return Value

Type: Integer

If the function succeed the return value is wclErrors.WCL_E_SUCCESS. Otherwise the method returns one of the WCL error codes.

The method starts a connection operation to a remote device. If the method success that does not mean that the connection was established. That just means that the connection operation was started. The real connection result will be passed to the OnConnect event handler.

NOTE: BlueSoleil does not support Authentication and Encryption parameters per connection.
