NAME

6       ubertooth-afh(1) - passive detection of AFH channel map
7

SYNOPSIS

9              ubertooth-afh -u <uap> -l <lap> [-r] [-m <seconds>]
10

DESCRIPTION

12       Classic Bluetooth piconets commonly make use of Adaptive Frequency Hop‐
13       ping (AFH) to avoid interference with other signals in  2.4  GHz.  This
14       tool  attempts  to determine the AFH map being used for a given piconet
15       identified by UAP and LAP.
16
17       At a minimum you must provide UAP and LAP. See  ubertooth-rx(1)  for  a
18       method  for  sniffing  these  over the air and details on where else to
19       find them. By default the tool will only print the AFH map when  it  is
20       updated.  By  providing the -r flag, the AFH map will be printed out in
21       binary form once per second.
22

OPTIONS

24              · -l <LAP> : LAP of target piconet (3 bytes / 6 hex digits)
25
26              · -u <UAP> : UAP of target piconet (1 byte / 2 hex digits)
27
28              · -m <int> : threshold for channel removal (default: 5)
29
30              · -r : print AFH channel map once every second  (default:  print
31                on update)
32
33       Other options:
34
35              · -t  <seconds>  :  timeout  for  initial AFH map detection (not
36                required)
37
38              · -e <0-4> : maximum access code errors (default: 2, range: 0-4)
39
40              · -V : print version information
41
42              · -U <0-7> : set ubertooth device to use
