android.permission.BLUETOOTH_PRIVILEGED in Android Things

Question

I have the following permission

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

in the android manifest.

Using this script to install the application in /system/priv-app:

How to install an app in system/app while developing from android studio

Now, I get this error:

 Caused by: java.lang.SecurityException: Needs com.google.android.things.permission.MANAGE_BLUETOOTH.: Neither user 10036 nor current process has com.google.android.things.permission.MANAGE_BLUETOOTH.
    at android.os.Parcel.readException(Parcel.java:2013)
    at android.os.Parcel.readException(Parcel.java:1959)

Even though it worked when installed normally.

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

Checking the requested versus granted permissions show that only com.google.android.things.permission.MANAGE_BLUETOOTH is missing.

Nothing changed

Android Things requires you to request the MANAGE_BLUETOOTH permission if you are accessing connection related APIs: https://developer.android.com/things/sdk/apis/bluetooth — devunwired, Sep 04 '19 at 17:53
This is most likely because you are trying to install your app into the /system partition directly, which Android Things does not formally support. The logic used to grant Android Things permissions is different than traditional Android permissions and it's not currently being triggered for your APK. — devunwired, Sep 06 '19 at 03:52
