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 -w.
-s <host>, --send-dump=<host>
Parse output is not printed to screen, instead data read from
device is sent to host host.
-n <host>, --recv-dump=<host>
Data is not read from a Bluetooth device, but from host host.
-d <host>, --wait-dump=<host>
Data is read from a Bluetooth device, but then send to host for
processing. No data is read if no host is connected.
-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
For every packet, only the raw data is displayed.
-C, --cmtp=<psm>
Sets the PSM value for the CAPI Message Transport Protocol.
-H, --hcrp=<psm>
Sets the PSM value for the Hardcopy Control Channel.
-O, --obex=<channel>
Sets the RFCOMM channel value for the Object Exchange Protocol.
-P, --ppp=<channel>
Sets the RFCOMM channel value for the Point-to-Point Protocol.
-D, --pppdump=<file>
Extract PPP traffic with pppdump format.
-A, --audio=<file>
Extract SCO audio data.
-B, --btsnoop
Use the BTSnoop file format.
-V, --verbose
Enables a more verbose decoding of every packet.
-Y, --novendor
Don’t display any vendor commands or events and don’t show any
pin code or link key in plain text.
-N, --noappend
No appending to existing files. Always create new files.
-4, --ipv4
Use IPv4 when sending information over the network
-6, --ipv6
Use IPv6 when sending information over the network
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,
all packets are dumped.
