HCIDUMP(1) Linux System Administration HCIDUMP(1)NAMEhcidump - Parse HCI data
SYNOPSIShcidump [-h]
hcidump [option [option...]] [filter]
DESCRIPTIONhcidump reads raw HCI data coming from and going to a Bluetooth device
(which can be specified with the option -i, default is the first avail‐
able 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 subse‐
quently parsed with option -r.
-r <file>, --read-dump=<file>
Data is not read from a Bluetooth device, but from file file.
