.SH DESCRIPTION
.LP
L2ping sends a L2CAP echo request to the Bluetooth MAC address
.I bd_addr
given in dotted hex notation.
.SH OPTIONS
.TP
.BI \-i " <hciX>"
The command is applied to device
.BI
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.
.TP
.BI \-s " size"
The
.I size
of the data packets to be sent.
.TP
.BI \-c " count"
Send
.I count
number of packets then exit.
.TP
.BI \-t " timeout"
Wait
.I timeout
seconds for the response.
.TP
.BI \-d " delay"
Wait
.I delay
seconds between pings.
.TP
.B \-f
Kind of flood ping. Use with care! It reduces the delay time between packets
to 0.
.TP
.B \-r
Reverse ping (gnip?). Send echo response instead of echo request.
.TP
.B \-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).
.TP
.I bd_addr
The Bluetooth MAC address to be pinged in dotted hex notation like
.B 01:02:03:ab:cd:ef
or
.B 01:EF:cd:aB:02:03
