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