On a mobile device, a public mesh Bluetooth service needs to be able to run uninterrupted in the background, and also need to be able to make Bluetooth advertisements and connections in the background. To do this, all of the Bluetooth-based branches of the testbed application request the following permissions:
<uses-permission
android:name="android.permission.ACCESS_COARSE_LOCATION"
android:maxSdkVersion="30" />
<uses-permission
android:name="android.permission.ACCESS_FINE_LOCATION"
android:maxSdkVersion="30" />
<!-- The BLUETOOTH permission was supposed to be removed in API 31 but is still needed on some Xiaomi/Redmi/POCO devices running API 31 and Nubia devices running API 32 -->

Depending on the API level, various permissions must be granted by the user. On API level 31, the following permissions require user confirmation:

Wi-Fi Direct requires various permissions on different Android API levels:

```
Depending on the API level, the user must grant either the location permission or the nearby Wi-Fi devices permission.
In practice, the system UI for requesting the `NEARBY_WIFI_DEVICES` permission also seems to grant the `BLUETOOTH_ADVERTISE`, `BLUETOOTH_CONNECT` and `BLUETOOTH_SCAN` permissions, and vice versa, but apps should probably not depend on this.
