l2test - L2CAP testing tool
DESCRIPTION
l2test - L2CAP testing tool Usage:
l2test <mode> [options] [bdaddr]
Modes:
-r listen and receive
-w listen and send
-d listen and dump incoming data
-x listen, then send, then dump incoming data
-t listen, then send and receive at the same time
-q connect, then send and receive at the same time
-s connect and send
-u connect and receive
-n connect and be silent
-y connect, then send, then dump incoming data
-c connect, disconnect, connect, ...
-m multiple connects
-p trigger dedicated bonding
-z information request
OPTIONS
[-b bytes] [-i device] [-P psm] [-J cid] [-I imtu] [-O omtu] [-L seconds] enable SO_LINGER [-W
seconds] enable deferred setup [-B filename] use data packets from file [-N num] send num frames
(default = infinite) [-C num] send num frames before delay (default = 1) [-D milliseconds] delay
after sending num frames (default = 0) [-K milliseconds] delay before receiving (default = 0) [-g
milliseconds] delay before disconnecting (default = 0) [-X mode] l2cap mode (help for list,
default = basic) [-a policy] chan policy (help for list, default = bredr) [-F fcs] use CRC16 check
(default = 1) [-Q num] Max Transmit value (default = 3) [-Z size] Transmission Window size
(default = 63) [-Y priority] socket priority [-H size] Maximum receive buffer size [-R] reliable
mode [-G] use connectionless channel (datagram) [-U] use sock stream [-A] request authentication
[-E] request encryption [-S] secure connection [-M] become master [-T] enable timestamps [-V type]
address type (help for list, default = bredr) [-e seq] initial sequence value (default = 0)
