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
