我正在尝试连接到 AnD UA-651BLE 血压计并在安卓应用程序中获取值。该应用程序能够找到该设备,但我在“onConnectionStateChange”中收到 Type_Gatt_Error。
这适用于某些设备,如三星 Galaxy S5、Moto G4 等,但不适用于某些手机,如 Redmi 3s Prime 等。
这很好用,当我取消配对设备并每次重新配对时,我都可以读取数据。我无法理解任何东西,因为我是 android-ble 集成的新手。我尝试将目标 SDK 版本更改为 21 和 23,因为我主要使用 android 5.0.1 及更高版本的设备。但没有运气
我发现门户网站中的许多人提出了类似的问题,但没有找到任何适合我的解决方案。
谁能让我理解为什么会发生这种情况以及可能的解决方案是什么?
以下是我在 Android Studio 中获得的日志:
