NAME

       l2ping - Send L2CAP echo request and receive answer

SYNOPSIS

       l2ping [OPTIONS] bd_addr

DESCRIPTION

       l2ping(1) 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
