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 speci-
fied, 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 be-
tween 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
