If no.Bcommandis given, or if the option.B-his used,.Bhcitoolprints some usage information and exits..SH OPTIONS.TP.BI -hGives a list of possible commands.TP.BI -i " <hciX>"The command is applied to device.IhciX, which must be the name of an installed Bluetooth device. If not specified,the command will be sent to the first available Bluetooth device..SH COMMANDS.TP.BI devDisplay local devices.TP.BI inqInquire remote devices. For each discovered device, Bluetooth device address,clock offset and class are printed..TP.BI scanInquire remote devices. For each discovered device, device name are printed..TP.BI name " <bdaddr>"Print device name of remote device with Bluetooth address.IR bdaddr ..TP.BI info " <bdaddr>"Print device name, version and supported features of remote device withBluetooth address.IR bdaddr ..TP.BI spinqStart periodic inquiry process. No inquiry results are printed..TP.BI epinqExit periodic inquiry process..TP.BI cmd " <ogf> <ocf> [parameters]"Submit an arbitrary HCI command to local device..IR ogf ,.IR ocfand.IR parametersare hexadecimal bytes..TP.BI conDisplay active baseband connections.TP.BI cc " [--role=m|s] [--pkt-type=<ptype>] <bdaddr>"Create baseband connection to remote device with Bluetooth address.IR bdaddr .Option.I--pkt-typespecifies a list of allowed packet types..I<ptype>is a comma-separated list of packet types, where the possible packet types are.BR DM1 ,.BR DM3 ,.BR DM5 ,.BR DH1 ,.BR DH3 ,.BR DH5 ,.BR HV1 ,.BR HV2 ,.BR HV3 .Default is to allow all packet types. Option.I--rolecan have value.Im(do not allow role switch, stay master) or.Is(allow role switch, become slave if the peer asks to become master). Default is.IR m ..TP.BI dc " <bdaddr> [reason]"Delete baseband connection from remote device with Bluetooth address.IR bdaddr .The reason can be one of the Bluetooth HCI error codes. Default is.IR 19for user ended connections. The value must be given in decimal..TP.BI sr " <bdaddr> <role>"Switch role for the baseband connection from the remote device to.BR masteror.BR slave ..TP.BI cpt " <bdaddr> <packet types>"Change packet types for baseband connection to device with Bluetooth address.IR bdaddr ..Ipacket typesis a comma-separated list of packet types, where the possible packet types are.BR DM1 ,.BR DM3 ,.BR DM5 ,.BR DH1 ,.BR DH3 ,.BR DH5 ,.BR HV1 ,.BR HV2 ,.BR HV3 ..TP.BI rssi " <bdaddr>"Display received signal strength information for the connection to the devicewith Bluetooth address.IR bdaddr ..TP.BI lq " <bdaddr>"Display link quality for the connection to the device with Bluetooth address.IR bdaddr ..TP.BI tpl " <bdaddr> [type]"Display transmit power level for the connection to the device with Bluetooth address.IR bdaddr .The type can be.BR 0for the current transmit power level (which is default) or.BR 1for the maximum transmit power level..TP.BI afh " <bdaddr>"Display AFH channel map for the connection to the device with Bluetooth address.IR bdaddr ..TP.BI lp " <bdaddr> [value]"With no.IR value ,displays link policy settings for the connection to the device with Bluetooth address.IR bdaddr .If.IR valueis given, sets the link policy settings for that connection to.IR value .Possible values are RSWITCH, HOLD, SNIFF and PARK..TP.BI lst " <bdaddr> [value]"With no.IR value ,displays link supervision timeout for the connection to the device with Bluetooth address.IR bdaddr .If.Ivalueis given, sets the link supervision timeout for that connection to.Ivalueslots, or to infinite if.Ivalueis 0..TP.BI auth " <bdaddr>"Request authentication for the device with Bluetooth address.IR bdaddr ..TP.BI enc " <bdaddr> [encrypt enable]"Enable or disable the encryption for the device with Bluetooth address.IR bdaddr ..TP.BI key " <bdaddr>"Change the connection link key for the device with Bluetooth address.IR bdaddr ..TP.BI clkoff " <bdaddr>"Read the clock offset for the device with Bluetooth address.IR bdaddr ..TP.BI clock " [bdaddr] [which clock]"Read the clock for the device with Bluetooth address.IR bdaddr .The clock can be.BR 0for the local clock or.BR 1for the piconet clock (which is default)..SH AUTHORSWritten by Maxim Krasnyansky <maxk@qualcomm.com> and Marcel Holtmann <marcel@holtmann.org>.PPman page by Fabrizio Gennari <fabrizio.gennari@philips.com>
