       hcitool - Configure Bluetooth connections

SYNOPSIS

       hcitool -h

       hcitool COMMAND --help

       hcitool [-i hciX] [COMMAND [PARAMETERS]]

DESCRIPTION

       hcitool(1) is used to configure Bluetooth connections and send some special command to Bluetooth devices.
       If no command is given, or if the option -h is used, hcitool prints some usage information and exits.

OPTIONS

       -i <hciX>
              The command is applied to device hciX, which must be the name of an installed Bluetooth device. If
              not specified, the command will be sent to the first available Bluetooth device.

       -h     Gives a list of possible commands

COMMANDS

       dev    Display local devices

       inq    Inquire  remote  devices.  For  each discovered device, Bluetooth device address, clock offset and
              class are printed.

       scan   Inquire remote devices. For each discovered device, device name are printed.

       name <bdaddr>
              Print device name of remote device with Bluetooth address bdaddr.

       info <bdaddr>
              Print device name, version and supported features of remote device with Bluetooth address bdaddr.

       spinq  Start periodic inquiry process. No inquiry results are printed.

       epinq  Exit periodic inquiry process.

       cmd <ogf> <ocf> [parameters]
              Submit an arbitrary HCI command to local device. ogf, ocf and parameters are hexadecimal bytes.

       con    Display active baseband connections

       cc [--role=c|p] [--pkt-type=<ptype>] <bdaddr>
              Create baseband connection to remote device with Bluetooth address bdaddr.

              Option --pkt-type specifies a list  of  allowed packet types.  <ptype> is a  comma-separated  list
              of  packet types, where the possible packet types are DM1, DM3, DM5, DH1, DH3, DH5, HV1, HV2, HV3.
              Default is to allow all packet types.

              Option  --role can have value c (do not allow role switch, stay central) or p (allow role  switch,
              become peripheral if the peer asks to become central). Default is c.

       dc <bdaddr> [reason]
              Delete baseband connection from remote device with Bluetooth address bdaddr.

              The reason can be one of the Bluetooth HCI error codes.  Default is 19 for user ended connections.
              The value must be given in decimal.

       sr <bdaddr> <role>
              Switch role for the baseband connection from the remote device to central or peripheral.

       cpt <bdaddr> <ptypes>
              Change  packet  types for baseband connection to device with Bluetooth address bdaddr. ptypes is a
              comma-separated list of packet types, where the possible packet types are DM1, DM3, DM5, DH1, DH3,
              DH5, HV1, HV2, HV3.

       rssi <bdaddr>
              Display received signal strength information for the  connection  to  the  device  with  Bluetooth
              address bdaddr.

       lq <bdaddr>
              Display link quality for the connection to the device with Bluetooth address bdaddr.

       tpl <bdaddr> [type]
              Display transmit power level for the connection to the device with Bluetooth address bdaddr.

              The  type  can  be  0 for the current transmit power level (which is default) or 1 for the maximum
              transmit power level.

       afh <bdaddr>
              Display AFH channel map for the connection to the device with Bluetooth address bdaddr.

       lp <bdaddr> [value]
              With no value, displays link policy settings for the  connection  to  the  device  with  Bluetooth
              address bdaddr.

              If value is given, sets the link policy settings for that connection to value. Possible values are
              RSWITCH, HOLD, SNIFF and PARK.

       lst <bdaddr> [value]
              With  no  value, displays link supervision timeout for the connection to the device with Bluetooth
              address bdaddr.

              If value is given, sets the link supervision timeout for that connection to  value  slots,  or  to
              infinite if value is 0.

       auth <bdaddr>
              Request authentication for the device with Bluetooth address bdaddr.
