NAME

   hcidump - Parse HCI data

SYNOPSIS

   hcidump [-h]
   hcidump [option [option...]] [filter]

DESCRIPTION

   hcidump  reads raw HCI data coming from and going to a Bluetooth device
   (which can be specified with  the  option  -i,  default  is  the  first
   available  one)  and  prints  to  screen commands, events and data in a
   human-readable form. Optionally, the dump can  be  written  to  a  file
   rather  than  parsed,  and  the dump file can be parsed in a subsequent
   moment.

OPTIONS

   -h     Prints usage info and exits

   -i <hciX>
          Data is read from hciX, which must be the name of  an  installed
          Bluetooth device. If not specified, and if -r option is not set,
          data is read from the first available Bluetooth device.

   -l <len>, --snap-len=<len>
          Sets max length of processed packets to len.

   -p <psm>, --psm=<psm>
          Sets default Protocol Service Multiplexer to psm.

   -m <compid>, --manufacturer=<compid>
          Sets default company id for manufacturer to compid.

   -w <file>, --save-dump=<file>
          Parse output is not printed to screen, instead  data  read  from
          device  is  saved  in  file  file.   The  saved dump file can be
          subsequently parsed with option -r.

   -r <file>, --read-dump=<file>
          Data is not read from a Bluetooth device, but  from  file  file.
          file is created with option -t, --timestamp Prepend a time stamp
          to every packet.

   -a, --ascii
          For every packet, not only is the  packet  type  displayed,  but
          also all data in ASCII.

   -x, --hex
          For  every  packet,  not  only is the packet type displayed, but
          also all data in hex.

   -X, --ext
          For every packet, not only is the  packet  type  displayed,  but
          also all data in hex and ASCII.

   -R, --raw

          pin code or link key in plain text.

FILTERS

   filter is  a  space-separated  list  of  packet  categories:  available
   categories  are  lmp,  hci,  sco, l2cap, rfcomm, sdp, bnep, cmtp, hidp,
   hcrp, avdtp, avctp, obex, capi and ppp.   If  filters  are  used,  only
   packets  belonging  to the specified categories are dumped. By default,
