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
