我如何獲得CBCharacteristicPropertyIndi​​cate的特性？

Question

在CoreBluetooth應用程序中，我想從通知切換到指示，以便我可以確保數據在另一端接收。

在Apple的示例代碼BTLE Central Peripheral Transfer中，我嘗試用CBCharacteristicPropertyIndicate代替CBCharacteristicPropertyNotify。這沒有用。外圍記錄：

所以看起來中心只得到了第一個消息，然後僅此而已。 你們有沒有人知道我做錯了什麼，以及如何獲得適應症？

Answer 1

嗯，也許你需要承認你已經閱讀它，然後才能收到更多？一次只能進行一次傳輸。
