.Sh NAME
.Nm l2ping
.Nd send L2CAP ECHO_REQUEST to remote devices
.Sh SYNOPSIS
.Nm
.Op Fl fh
.Fl a Ar BD_ADDR
.Op Fl c Ar count
.Op Fl i Ar delay
.Op Fl S Ar BD_ADDR
.Op Fl s Ar size
.Sh DESCRIPTION
The
.Nm
utility uses L2CAP
.Dv ECHO_REQUEST
datagram to elicit an L2CAP
.Dv ECHO_RESPONSE
from a remote device.
.Pp
The options are as follows:
.Bl -tag -width indent
.It Fl a Ar BD_ADDR
Address of remote device to ping.
Example:
.Fl a Li 00:01:02:03:04:05 .
.It Fl c Ar count
Number of packets to send.
If this option is not specified,
.Nm
will operate until interrupted.
.It Fl f
.Dq Flood
ping, i.e., no delay between packets.
.It Fl h
Display usage message and exit.
.It Fl i Ar wait
Wait
.Ar wait
seconds between sending each packet.
The default is to wait for one second between each packet.
This option is ignored if
.Fl f
has been specified.
.It Fl S Ar BD_ADDR
Send L2CAP
.Dv ECHO_REQUEST
from local device that has
.Ar BD_ADDR .
Example:
.Fl S Li 00:05:04:03:02:01 .
.It Fl s Ar size
Specify the number of payload bytes to be sent.
The default is the minimum L2CAP MTU minus the size of the L2CAP signalling
command header (44 bytes).
The maximum size is 65531.
Use this option with caution.
Some implementations may not like large sizes and may hang or even crash.
.El
.Sh BUGS
Could collect more statistic.
Could check for duplicated, corrupted and lost packets.
