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

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
