.SH NAME

.SH SYNOPSIS
.sp
\fBl2ping\fP [\fIOPTIONS\fP] \fIbd_addr\fP
.SH DESCRIPTION
.sp
\fBl2ping(1)\fP sends a L2CAP echo request to the Bluetooth MAC address bd_addr
given in dotted hex notation.
.SH OPTIONS
.INDENT 0.0
.TP
.BI \-i \ <hciX>
The command is applied to device \fIhciX\fP, 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 size of the data packets to be sent.
.TP
.BI \-c \ count
Send count number of packets then exit.
.TP
.BI \-t \ timeout
Wait timeout seconds for the response.
.TP
.BI \-d \ delay
Wait 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).
.UNINDENT
.INDENT 0.0
.TP
.B bd_addr
The Bluetooth MAC address to be pinged in dotted hex notation
like \fB01:02:03:ab:cd:ef\fP or \fB01:EF:cd:aB:02:03\fP
