       hcitool - configure Bluetooth connections

SYNOPSIS

       hcitool [-h]
       hcitool [-i <hciX>] [command [command parameters]]

DESCRIPTION

       hcitool 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

       -h     Gives a list of possible commands

       -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.

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=m|s] [--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 m (do not allow role switch, stay master) or
              s (allow role switch, become slave if the peer asks to become master). Default is m.

       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 master or slave.

       cpt <bdaddr> <packet types>
              Change packet types for baseband connection to device with Bluetooth address bdaddr.  packet types
              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.
