android - BLE 扫描是否适用于没有 GPS 芯片的平板电脑？

Question

我在 BLE 应用程序中工作。我对执行 BLE 扫描的 GPS 权限有一些疑问。

BLE 扫描是否适用于没有 GPS 芯片的平板电脑？

startLescan() 可以在没有 GPS 许可的情况下工作吗？

Answer 1

BLE 与 GPS 毫无关系。这里有详细解释:https://developer.android.com/guide/topics/connectivity/bluetooth-le

您可能需要声明以下权限:

<uses-permission android:name="android.permission.BLUETOOTH"/>
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>

<!-- If your app targets Android 9 or lower, you can declare
     ACCESS_COARSE_LOCATION instead. -->
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

注意:虽然实际上没有使用 GPS，但您必须声明 ACCESS_COARSE_LOCATION或 ACCESS_FINE_LOCATION使事情正常工作，因为信标通常用于提供位置信息。
