HCIDUMP(1)		     General Commands Manual		      HCIDUMP(1)

NAME
     hcidump -- Parse HCI data

SYNOPSIS
     hcidump [-h]
     hcidump [-aRtx] [-i HCI_node] [-p PSM] [-r file] [-s length] [-w file]
	     [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  all  available  de-
     vices)  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
     -a      For  every  packet, not only is the packet type displayed, but also
	     all data in ASCII format.

     -h      Prints usage info and exits.

     -i HCI_node
	     Data is read from the specified device.  If not specified,  and  if
	     -r option is not set, data is read from the all available Bluetooth
	     devices.

     -p PSM  Sets default Protocol Service Multiplexer (PSM) to specified value.

     -R      Raw mode: do not display packet type, only data.

     -r file
	     Data  is  not  read from a Bluetooth device, but from the specified
	     file.  The file can be created with option -w.

     -s length
	     Sets max length of processed packets.

     -t      Prepend a time stamp to every packet.

     -w file
	     Parsed output is not printed to screen, instead data read from  the
	     device  are saved into the specified file.  The saved dump file can
	     be subsequently parsed with option -r.

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

FILTERS
     Filter is a space-separated list of packet categories: available categories
     are  bnep,  cmtp,	hci,  hidp,  l2cap, rfcomm, sco and sdp.  If filters are
     used, only packets belonging to the specified categories  are  dumped.   By
     default, all packets are dumped.
