如何知道是否发送了BLE通知？

我用psoc4 BLE和发送通知给同伴时，我的设备关闭，用原因代码使同伴知道为什么我被关闭的设备（如用户行为，闲置超时、电池低等等）。显然，在关机后cyble_gattsnotification()我需要循环cyble_processevents()，但我也要避免不必要的循环太长。
那么有没有办法知道如果/当我通知了吗？这是一个迹象，所以我不在乎同伴不会/不能处理它，所以没有必要使用指示和等待同伴的确认。所有我想知道的是，如果是送我的消息，而如果同伴得到它或不。
谢谢，
卡洛里

  I am using the PSoC4 BLE and sending a notification to the peer when my device shuts down, with a reason code so that the peer knows why my device was turned off (e.g. user action, inactivity timeout, battery low and so on). Obviously on shutdown after CyBle_GattsNotification() I  need to loop on CyBle_ProcessEvents(), but I also want to avoid looping too long unnecessarily.

So is there a way to know if / when my notification was put on air? This is an indication so I don't care if the peer doesn't / cannot process it, so there is no need to e.g. use indication and wait for the peer to confirm. All I want to know is if my message was sent, irrespective if the peer got it or not.

Thx,
