33 .Nd send L2CAP ECHO_REQUEST to remote devices
47 datagram to elicit an L2CAP
49 datagram from a remote device.
51 The options are as follows:
52 .Bl -tag -width indent
54 Specify the remote device to ping.
55 The remote device can be specified by either its BD_ADDR or name.
56 If name was specified then the
58 utility will attempt to resolve the name via
59 .Xr bt_gethostbyname 3 .
61 Number of packets to send.
62 If this option is not specified,
64 will operate until interrupted.
66 Do not wait between sending each packet.
68 Display usage message and exit.
72 seconds between sending each packet.
73 The default is to wait for one second between each packet.
74 This option is ignored if
79 No attempt will be made to look up symbolic names for host addresses.
81 Specify the local device which should be used to send L2CAP
84 The local device can be specified by either its BD_ADDR or name.
85 If name was specified then the
87 utility will attempt to resolve the name via
88 .Xr bt_gethostbyname 3 .
90 Specify the number of payload bytes to be sent.
91 The default size is 44 bytes.
92 It is calculated as minimum L2CAP MTU (48 bytes) minus the size of the L2CAP
93 signalling command header (4 bytes).
94 The maximum size is 65531 bytes.
95 Is is calculated as maximum L2CAP MTU
96 (65535 bytes) minus four bytes of payload reserved for
99 Use this option with caution.
100 Some implementations may not like large sizes and may hang or even crash.
111 .An Maksim Yevmenkin Aq emax@FreeBSD.org
113 Could collect more statistic.
114 Could check for duplicated, corrupted and lost packets.
