       l2ping - Send L2CAP echo request and receive answer


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


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


       -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

       -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).

              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
