public abstract class L2capChannel

  1. Object
  2. L2capChannel

An open L2CAP connection-oriented channel – a raw bidirectional byte stream to a peripheral, obtained via BlePeripheral.openL2capChannel(int, boolean) on the central side or accepted from an L2capServer on the peripheral side.

The streams block and must be consumed off the EDT; reads/writes throw plain java.io.IOException on transport failure. Always close() the channel when done.

Constructors

protected L2capChannel(int psm)Constructed by ports; not application API.

Methods

public abstract InputStream getInputStream() throws IOExceptionThe blocking input stream of the channel; consume off the EDT.
public abstract OutputStream getOutputStream() throws IOExceptionThe blocking output stream of the channel; use off the EDT.
public abstract void close() throws IOExceptionCloses the channel and both streams.
public abstract boolean isOpen()true while the channel is open.
public int getPsm()The Protocol/Service Multiplexer this channel is bound to.
