  • Send a SubscribeEventgroupAck / Nack entry using Unicast considering the appropriate delay without changing the current counter value and without influencing the current running repetition timer/repetition phase or timer/main phase.
    考虑适当的延迟, 使用Unicast发送SubscribeEventgroupAck / Nack entry, 且不改变当前Counter值,也不影响当前运行的timer。
  • Call the BswM with the API BswM_Sd_EventHandlerCurrentState() with state SD_EVENT_HANDLER_REQUESTED only if the state for this EventHandler changed (i.e. has not been SD_EVENT_HANDLER_REQUESTED) .
    仅当此此EventHandler的状态改变(即尚不是SD_EVENT_HANDLER_REQUESTED)时,将状态SD_EVENT_HANDLER_REQUESTED赋值给API BswM_Sd_EventHandlerCurrentState() 并通知BswM。

  • If this has been the last subscribed client, report “SD_EVENT_HANDLER_RELEASED” to the BswM by calling the API BswM_Sd_EventHandlerCurrentState() and update the state within the Service Discovery Module.
    如果这是最后一个订阅的客户端,则通过调用API BswM_Sd_EventHandlerCurrentState()将状态更新为 “SD_EVENT_HANDLER_RELEASED”,并报告给BswM报告。

StopSubscribeEventgroup Entry:

  • Stop the TTL timer for this client
    停止这个客户端的TTL计时器
