Connects to a remote device.

Syntax
Pascal
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 
Description 
const Address: Int64 
The remote Bluetooth device address.  
const Service: 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.  
const Channel: Byte = 0 
The RFCOMM channel number. If zero the Service UUID will be used.  
const Authentication: Boolean = True 
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.  
const Encryption: Boolean = False 
The option enforces encryption to establish a connection. Encryption is only available for authenticated connections.  
const Timeout: Cardinal = 10000 
The connect timeout in milliseconds. The default value is 10000 milliseconds.  

If the function succeed the return value is 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.
