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
       devices)	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	speci-
	       fied 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	 cate-
       gories  are bnep, cmtp, hci, hidp, l2cap, rfcomm, sco and sdp.  If fil-
       ters are	used, only packets belonging to	the specified  categories  are
       dumped.	By default, all	packets	are dumped.
