The
+.Fn bt_devremote_name
+function performs Bluetooth Remote Name Request procedure to obtain the
+user-friendly name of another Bluetooth unit.
+The
+.Fa devname
+parameter specifies which local Bluetooth device should perform the request.
+If not specified
+.Dv ( NULL ) ,
+the first available device is used.
+The
+.Fa remote
+parameter specifies the Bluetooth BD_ADDR of the remote device to query.
+The
+.Fa to
+parameter specifies response timeout in seconds.
+If not specified (0), the default value is taken from the
+net.bluetooth.hci.command_timeout
+.Xr sysctl 8
+value.
+The
+.Fa clk_off ,
+.Fa ps_rep_mode ,
+and
+.Fa ps_mode
+parameters specify Clock_Offset, Page_Scan_Repetition_Mode, and Page_Scan_Mode
+fields of HCI_Remote_Name_Request respectively.
+On success, the function returns a pointer to dynamically allocated
+NUL-terminated string or
+.Dv NULL
+if an error occurred.
+It is up to the caller to release returned string using
+.Xr free 3 .
+.Pp
+The
+.Fn bt_devremote_name_gen
+function is a shortcut to
+.Fn bt_devremote_name
+that passes generic defaults for
+.Fa to ,
+.Fa clk_off ,

+.Fa ps_mode
+parameters.
+.Pp
+The
.Fn bdaddr_same ,
-.Fn bdaddr_any

and

are handy shorthand Bluetooth address utility functions.
