Interface DiscoveryListener

public interface DiscoveryListener

The DiscoveryListener interface allows an application to receive device discovery and service discovery events. This interface provides four methods, two for discovering devices and two for discovering services.

Since:

BlackBerry API 4.2.1

Field Summary
static int	INQUIRY_COMPLETED Indicates the normal completion of device discovery.
static int	INQUIRY_ERROR Indicates that the inquiry request failed to complete normally, but was not cancelled.
static int	INQUIRY_TERMINATED Indicates device discovery has been canceled by the application and did not complete.
static int	SERVICE_SEARCH_COMPLETED Indicates the normal completion of service discovery.
static int	SERVICE_SEARCH_DEVICE_NOT_REACHABLE Indicates the service search could not be completed because the remote device provided to DiscoveryAgent.searchServices() could not be reached.
static int	SERVICE_SEARCH_ERROR Indicates the service search terminated with an error.
static int	SERVICE_SEARCH_NO_RECORDS Indicates the service search has completed with no service records found on the device.
static int	SERVICE_SEARCH_TERMINATED Indicates the service search has been canceled by the application and did not complete.

Method Summary
void	deviceDiscovered(RemoteDevice btDevice, DeviceClass cod) Called when a device is found during an inquiry.
void	inquiryCompleted(int discType) Called when an inquiry is completed.
void	serviceSearchCompleted(int transID, int respCode) Called when a service search is completed or was terminated because of an error.

Method Detail

deviceDiscovered

void deviceDiscovered(RemoteDevice btDevice,
                      DeviceClass cod)

Called when a device is found during an inquiry. An inquiry searches for devices that are discoverable. The same device may be returned multiple times.

Parameters:

btDevice - the device that was found during the inquiry

cod - the service classes, major device class, and minor device class of the remote device

DiscoveryAgent.startInquiry(int, javax.bluetooth.DiscoveryListener)

Since:

BlackBerry API 4.2.1

servicesDiscovered

void servicesDiscovered(int transID,
                        ServiceRecord[] servRecord)

Called when service(s) are found during a service search.

Parameters:

transID - the transaction ID of the service search that is posting the result

service - a list of services found during the search request

See Also:

DiscoveryAgent.searchServices(int[], javax.bluetooth.UUID[], javax.bluetooth.RemoteDevice, javax.bluetooth.DiscoveryListener)

Since:

BlackBerry API 4.2.1

serviceSearchCompleted

void serviceSearchCompleted(int transID,
                            int respCode)

Called when a service search is completed or was terminated because of an error. Legal status values in the respCode argument include SERVICE_SEARCH_COMPLETED, SERVICE_SEARCH_TERMINATED, SERVICE_SEARCH_ERROR, SERVICE_SEARCH_NO_RECORDS and SERVICE_SEARCH_DEVICE_NOT_REACHABLE. The following table describes when each respCode will be used:

respCode	Reason
SERVICE_SEARCH_COMPLETED	if the service search completed normally
SERVICE_SEARCH_TERMINATED	if the service search request was cancelled by a call to DiscoveryAgent.cancelServiceSearch()
SERVICE_SEARCH_ERROR	if an error occurred while processing the request
SERVICE_SEARCH_NO_RECORDS	if no records were found during the service search
SERVICE_SEARCH_DEVICE_NOT_REACHABLE	if the device specified in the search request could not be reached or the local device could not establish a connection to the remote device

Parameters:

transID - the transaction ID identifying the request which initiated the service search

respCode - the response code that indicates the status of the transaction

Since:

BlackBerry API 4.2.1

inquiryCompleted

void inquiryCompleted(int discType)

Called when an inquiry is completed. The discType will be INQUIRY_COMPLETED if the inquiry ended normally or INQUIRY_TERMINATED if the inquiry was canceled by a call to DiscoveryAgent.cancelInquiry(). The discType will be INQUIRY_ERROR if an error occurred while processing the inquiry causing the inquiry to end abnormally.

Parameters:

discType - the type of request that was completed; either INQUIRY_COMPLETED, INQUIRY_TERMINATED, or INQUIRY_ERROR
