NAME

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 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
