NAME

       l2ping - Send L2CAP echo request and receive answer

SYNOPSIS

       l2ping  [-i  <hciX>]  [-s size] [-c count] [-t timeout] [-d delay] [-f]
       [-r] [-v] bd_addr

DESCRIPTION

       L2ping sends a L2CAP echo request to the Bluetooth MAC address  bd_addr
       given in dotted hex notation.

OPTIONS

       -i <hciX>
              The  command  is applied to device hciX , which must be the name
              of an installed Bluetooth device (X = 0,  1,  2,  ...)   If  not
              specified,  the  command  will  be  sent  to the first available
              Bluetooth device.

       -s size
              The size of the data packets to be sent.

       -c count
              Send count number of packets then exit.

       -t timeout
              Wait timeout seconds for the response.

       -d delay
              Wait delay seconds between pings.

       -f     Kind of flood ping. Use with care! It  reduces  the  delay  time
              between packets to 0.

       -r     Reverse  ping  (gnip?).  Send  echo  response  instead  of  echo
              request.

       -v     Verify response payload is identical to request payload.  It  is
              not  required  for  remote stacks to return the request payload,
              but most stacks do (including Bluez).

       bd_addr
              The Bluetooth MAC address to be pinged in  dotted  hex  notation
              like 01:02:03:ab:cd:ef or 01:EF:cd:aB:02:03
