The .Nm utility will print results to the standard output and error messages to the standard error. .Pp The options are as follows: .Bl -tag -width indent .It Fl h Display usage message and exit. .It Fl N Show Bluetooth addresses as numbers. Normally .Nm attempts to resolve Bluetooth addresses, and display them symbolically. .It Fl n Ar HCI_node_name Connect to the specified HCI Netgraph node. .It Ar command One of the supported commands (see below). The special command .Cm help can be used to obtain the list of all supported commands. To get more information about a specific command use .Cm help Ar command . .It Ar parameters One or more optional space separated command parameters. Many commands require a remote device address as one of the parameters. The remote device address can be specified as BD_ADDR or a name. If a name was specified then the .Nm utility will attempt to resolve the name via .Xr bt_gethostbyname 3 . .El .Sh COMMANDS The currently supported HCI commands in .Nm are: .Pp .Bl -tag -width 40n -offset indent -compact .It Cm Inquiry .It Cm Create_Connection .It Cm Disconnect .It Cm Add_SCO_Connection .It Cm Change_Connection_Packet_Type .It Cm Remote_Name_Request .It Cm Read_Remote_Supported_Features .It Cm Read_Remote_Version_Information .It Cm Read_Clock_Offset .It Cm Role_Discovery .It Cm Switch_Role .It Cm Read_Link_Policy_Settings .It Cm Write_Link_Policy_Settings .It Cm Reset .It Cm Read_Pin_Type .It Cm Write_Pin_Type .It Cm Read_Stored_Link_Key .It Cm Write_Stored_Link_Key .It Cm Delete_Stored_Link_Key .It Cm Change_Local_Name .It Cm Read_Local_Name .It Cm Read_Connection_Accept_Timeout .It Cm Write_Connection_Accept_Timeout .It Cm Read_Page_Timeout .It Cm Write_Page_Timeout .It Cm Read_Scan_Enable .It Cm Write_Scan_Enable .It Cm Read_Page_Scan_Activity .It Cm Write_Page_Scan_Activity .It Cm Read_Inquiry_Scan_Activity .It Cm Write_Inquiry_Scan_Activity .It Cm Read_Authentication_Enable .It Cm Write_Authentication_Enable .It Cm Read_Encryption_Mode .It Cm Write_Encryption_Mode .It Cm Read_Class_Of_Device .It Cm Write_Class_Of_Device .It Cm Read_Voice_Settings .It Cm Write_Voice_Settings .It Cm Read_Number_Broadcast_Retransmissions .It Cm Write_Number_Broadcast_Retransmissions .It Cm Read_Hold_Mode_Activity .It Cm Write_Hold_Mode_Activity .It Cm Read_SCO_Flow_Control_Enable .It Cm Write_SCO_Flow_Control_Enable .It Cm Read_Link_Supervision_Timeout .It Cm Write_Link_Supervision_Timeout .It Cm Read_Page_Scan_Period_Mode .It Cm Write_Page_Scan_Period_Mode .It Cm Read_Page_Scan_Mode .It Cm Write_Page_Scan_Mode .It Cm Read_LE_Host_Support .It Cm Write_LE_Host_Support .It Cm Read_Local_Version_Information .It Cm Read_Local_Supported_Commands .It Cm Read_Local_Supported_Features .It Cm Read_Buffer_Size .It Cm Read_Country_Code .It Cm Read_BD_ADDR .It Cm Read_Failed_Contact_Counter .It Cm Reset_Failed_Contact_Counter .It Cm Get_Link_Quality .It Cm Read_RSSI .It Cm LE_Enable .It Cm LE_Read_Local_Supported_Features .It Cm LE_Set_Advertising_Parameters .It Cm LE_Read_Advertising_Physical_Channel_Tx_Power .It Cm LE_Set_Advertising_Data .It Cm LE_Set_Scan_Response_Data .It Cm LE_Set_Advertising_Enable .It Cm LE_Set_Scan_Parameters .It Cm LE_Set_Scan_Enable .It Cm LE_Read_Supported_States .It Cm LE_Read_Buffer_Size .It Cm LE Scan .It Cm LE_Read_White_List_Size .It Cm LE_Clear_White_List .It Cm LE_Add_Device_To_White_List .It Cm LE_Remove_Device_From_White_List .It Cm LE_Connect .It Cm LE_Read_Channel_Map .It Cm LE_Read_Remote_Features .It Cm LE_Rand .El .Pp The currently supported node commands in .Nm are: .Pp .Bl -tag -width 40n -offset indent -compact .It Cm Read_Node_State .It Cm Initialize .It Cm Read_Debug_Level .It Cm Write_Debug_Level .It Cm Read_Node_Buffer_Size .It Cm Read_Node_BD_ADDR .It Cm Read_Node_Features .It Cm Read_Node_Stat .It Cm Reset_Node_Stat .It Cm Flush_Neighbor_Cache .It Cm Read_Neighbor_Cache .It Cm Read_Connection_List .It Cm Read_Node_Link_Policy_Settings_Mask .It Cm Write_Node_Link_Policy_Settings_Mask .It Cm Read_Node_Packet_Mask .It Cm Write_Node_Packet_Mask .It Cm Read_Node_Role_Switch .It Cm Write_Node_Role_Switch .It Cm Read_Node_List .El .Sh EXIT STATUS .Ex -std .Sh EXAMPLES Make the blutooth LE host, ubt0hci, scannable through .Xr hccontrol 8 commands: .Bd -literal -offset indent hccontrol -n ubt0hci le_set_advertising_enable disable hccontrol -n ubt0hci le_set_advertising_param hccontrol -n ubt0hci le_read_advertising_channel_tx_power hccontrol -n ubt0hci le_set_advertising_data hccontrol -n ubt0hci le_set_scan_response -n FBSD_Host hccontrol -n ubt0hci le_set_advertising_enable enable .Ed .Sh SEE ALSO .Xr bluetooth 3 , .Xr netgraph 3 , .Xr netgraph 4 , .Xr ng_hci 4 .Sh AUTHORS .An Maksim Yevmenkin Aq Mt m_evmenkin@yahoo.com .Sh BUGS Most likely.
