typedef struct _BtctlController BtctlController;

btctl_controller_new ()

BtctlController* btctl_controller_new       (const char *hci_device);

Create a new Bluetooth controller object. This will attempt to open an HCI socket to the default Bluetooth device. Use btctl_controller_is_initialised() to check whether this was successful.

Link an rfcomm device to the destination device. Returns BTCTL_RFCOMM_NO_DEVICE if the connection cannot be made.

btctl_controller_get_established_rfcomm_connection ()

gint        btctl_controller_get_established_rfcomm_connection
                                            (BtctlController *bc,

                                             guint channel);

Find rfcomm device number (ie. N for /dev/rfcommN) connected to the destination device on the specified channel. Returns BTCTL_RFCOMM_NO_DEVICE is no device is available, or BTCTL_RFCOMM_DEVICE_IN_USE if a device is available but already in use.

btctl_controller_scan_for_service ()

void        btctl_controller_scan_for_service
                                            (BtctlController *bc,
                                             const gchar *bdstr,
                                             guint clsid);

Performs a specific SDP scan for the service specified. The service class identifiers can be found in /usr/include/bluetooth/sdp.h

btctl_controller_cancel_discovery ()

void        btctl_controller_cancel_discovery
                                            (BtctlController *bc);

Cancel an asynchronous discovery cycle. Will only work if inquiry cancellation support is present in the kernel.

btctl_controller_discover_async ()

void        btctl_controller_discover_async (BtctlController *bc);

Commence an asychronous device discovery cycle. Signals will be sent on device discovery, but no SDP discovery is being done. The status-change signal will send information about the completion of the scan.

btctl_controller_is_initialised ()

gboolean    btctl_controller_is_initialised (BtctlController *bc,
                                             GError **err);

Check if controller was able to get the Bluetooth HCI connection. If not, we won't be able to do anything like discovery.

btctl_controller_get_signal_strength ()

int         btctl_controller_get_signal_strength
                                            (BtctlController *bc,
                                             const gchar *bdaddr,
                                             GError **err);

Bluetooth allows the monitoring of the signal strength of an established connection. There must be an existing connection for this function to work.
