HCIDUMP(1)		FreeBSD	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 Blue-
	     tooth 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 cate-
     gories 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.
