Class L2capChannel

java.lang.Object
com.codename1.bluetooth.le.L2capChannel
public abstract class L2capChannel extends Object

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.
