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
              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.

       -Y, --novendor
              Don't display any vendor commands or events and don't show any 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, all packets are dumped.
