Question

这是我的问题我有一个使用BLE的电子锁，它在ios上工作正常（LightBlue和我制造的应用程序）
但是在Android上，在与锁定绑定后（我输入了密码000000），我可以连接到设备，但其中一个服务（UUID：7570）变空，我无法读取或写入任何设备特征。
此外，设备在大约20秒后总是断开连接。

这是来自ios的ScreenShot

这是来自android的ScreenShot（空服务）

这是我从nRF Connect获得的日志

我已在使用不同测试应用的不同Android手机上对其进行了测试这是BLE设备的问题吗？

如果需要更具体的细节，请告诉我任何帮助或建议将不胜感激。谢谢！

Answer 1

设备在大约20秒后总是断开连接

这是因为监督超时。在Android中，它被硬编码为20秒，在此期间重新连接不起作用。有关更多信息，请了解这20秒和监督超时的内容 - Android BLE connection timeouts and GATT internal errors

BLE设备适用于ios但不适用于Android
