      extended by org.llrp.ltk.generated.messages.KEEPALIVE

public class KEEPALIVE
extends LLRPMessage

This message is issued by the Reader to the Client. This message can be used by the Client to monitor the LLRP-layer connectivity with the Reader. The Client configures the trigger at the Reader to send the Keepalive message. The configuration is done using the KeepaliveSpec parameter (section 12.2.4). See also LLRP Specification Section 13.1.3 and LLRP Specification Section 16.1.31
