NAME
       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.

       enc <bdaddr> [encrypt]
              enable or disable the encryption for the device with Bluetooth address bdaddr.

       key <bdaddr>
              Change the connection link key for the device with Bluetooth address bdaddr.

       clkoff <bdaddr>
              Read the clock offset for the device with Bluetooth address bdaddr.

       clock [bdaddr] [clock]
              Read the clock for the device with Bluetooth address bdaddr.

              The clock can be 0 for the local clock or 1 for the piconet clock (which is default).
