Optionally, the dump can be written to a filerather than parsed, and the dump file can be parsed in a subsequent moment..SH OPTIONS.TP.BI -hPrints usage info and exits.TP.BI -i " <hciX>"Data is read from.IR hciX ,which must be the name of an installed Bluetooth device. If not specified,and if.B-roption is not set, data is read from the first available Bluetooth device..TP.BI -l " <len>" "\fR,\fP \-\^\-snap-len=" "<len>"Sets max length of processed packets to.IR len ..TP.BI -p " <psm>" "\fR,\fP \-\^\-psm=" "<psm>"Sets default Protocol Service Multiplexer to.IR psm ..TP.BI -m " <compid>" "\fR,\fP \-\^\-manufacturer=" "<compid>"Sets default company id for manufacturer to.IR compid ..TP.BI -w " <file>" "\fR,\fP \-\^\-save-dump=" "<file>"Parse output is not printed to screen, instead data read from device is saved in file.IR file .The saved dump file can be subsequently parsed with option.BR -r ..TP.BI -r " <file>" "\fR,\fP \-\^\-read-dump=" "<file>"Data is not read from a Bluetooth device, but from file.IR file ..Ifileis crated with option.BR -w ..TP .BI -s " <host>" "\fR,\fP \-\^\-send-dump=" "<host>"Parse output is not printed to screen, instead data read from device is send to host.IR host ..TP .BI -n " <host>" "\fR,\fP \-\^\-recv-dump=" "<host>"Data is not read from a Bluetooth device, but from host.IR host ..TP.BR -t ", " "\-\^\-timestamp"Prepend a time stamp to every packet..TP.BR -a ", " "\-\^\-ascii"For every packet, not only is the packet type displayed, but also all data in ASCII..TP.BR -x ", " "\-\^\-hex"For every packet, not only is the packet type displayed, but also all data in hex..TP.BR -X ", " "\-\^\-ext"For every packet, not only is the packet type displayed, but also all data in hex and ASCII..TP.BR -R ", " "\-\^\-raw"For every packet, only the raw data is displayed..TP.BR -C ", " "\-\^\-cmtp"Sets the PSM value for the CAPI Message Transport Protocol.TP.BR -H ", " "\-\^\-hcrp"Sets the PSM value for the Hardcopy Control Channel.TP.BR -O ", " "\-\^\-obex"Sets the RFCOMM channel value for the Object Exchange protocol.TP.BR -V ", " "\-\^\-verbose"Enables a more verbose decoding of every packet..SH FILTERS.Bfilteris a space-separated list of packet categories: available categories are.IR lmp ,.IR hci ,.IR sco ,.IR l2cap ,.IR rfcomm ,.IR sdp ,.IR bnep ,.IR cmtp ,.IR hidp ,.IR hcrp ,.IR avdtp ,.IR obexand.IR capi .If filters are used, only packets belonging to the specified categories aredumped.
