NAME

       ubertooth-afh - passive detection of AFH channel map

SYNOPSIS

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

DESCRIPTION

       Classic  Bluetooth piconets commonly make use of Adaptive Frequency Hopping (AFH) to avoid
       interference with other signals in 2.4 GHz. This tool attempts to determine  the  AFH  map
       being used for a given piconet identified by UAP and LAP.

       At  a  minimum you must provide UAP and LAP. See ubertooth-rx(1) for a method for sniffing
       these over the air and details on where else to find them. By default the tool  will  only
       print  the  AFH  map  when  it  is  updated. By providing the -r flag, the AFH map will be
       printed out in binary form once per second.

OPTIONS

-l <LAP> : LAP of target piconet (3 bytes / 6 hex digits)

              • -u <UAP> : UAP of target piconet (1 byte / 2 hex digits)

              • -m <int> : threshold for channel removal (default: 5)

              • -r : print AFH channel map once every second (default: print on update)

       Other options:

              • -t <seconds> : timeout for initial AFH map detection (not required)

              • -e <0-4> : maximum access code errors (default: 2, range: 0-4)

              • -V : print version information

              • -U <0-7> : set ubertooth device to use
