JSR-82 defines the L2CAPConnectionNotifier and L2CAPConnection interfaces
for sending and receiving packets over L2CAP channels. These are derived from
the CLDC Generic Connection Framework interface Connection.
An L2CAP server is created by calling Connector.open() with
an appropriate server connection string. The format of the string is defined
by JSR-82. The connector string begins with the protocol prefix “btl2cap://”
and may contain parameters related to a master/slave preference, or security
parameters (authentication, encryption, and authorization). It may also contain
parameters related to the application’s preference for a desired Maximum Transmit
Unit (MTU) size in the send and/or receive directions. An L2CAPConnectionNotifier object
is returned when opening a server connection. The method acceptAndOpen can
be used to accept connections from remote clients.
L2CAP packets are sent or received using the send and receive methods
of class L2CAPConnection. An application using L2CAP
connections must provide its own flow control if needed.
L2CAP clients are created in a similar way with method Connector.open() using
a client connection string.
