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.
-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
