如何使用CBCharacteristicPropertyIndi​​cate工作？

Question

在CoreBluetooth应用程序中，我想从通知切换到指示，以便我可以确保在另一方收到数据。

在Apple的示例代码BTLE Central Peripheral Transfer中，我尝试将CBCharacteristicPropertyNotify替换为CBCharacteristicPropertyIndicate。那没用。记录的外围设备：

中央记录：

所以看起来中央只得到了第一条消息，然后再没有了。 你们有谁知道我做错了什么，以及如何获得适应症的指示？

Answer 1

嗯，也许你需要承认你已经读过它才能收到更多？一次只能完成一次转移。
