l2ping – Send L2CAP echo request and receive answer
L2ping sends a L2CAP echo request to the Bluetooth MAC address bd_addr
given in dotted hex notation.
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 Blue‐
The size of the data packets to be sent.
Send count number of packets then exit.
Wait timeout seconds for the response.
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
