       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.

       enc <bdaddr> [encrypt enable]
	      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] [which 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
