Root required?

[gtbX]

Trying to run this on unrooted Nexus 6, but doesn't seem to work. I see this error in logcat after pairing:

D/HidPeripheral: Need BLUETOOTH PRIVILEGED permission: Neither user 10102 nor current process has android.permission.BLUETOOTH_PRIVILEGED.

According to docs, BLUETOOTH_PRIVILEGED is not allowed for 3rd party apps.

seems like the sort of thing that needs to be manually added via adb or automatically via su (root).

should take a peek at open source apps with similar special permission needs like this logcat reader:
