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.
-c timeout: Wait timeout seconds for the response.
-f: Kind of flood ping. Use with care! It reduces the delay time between packets to 0.
