Android docs says 'Not for use by third-party applications.'
BLUETOOTH PRIVILEGED

How do I make it work?

Not sure, but this suggest that it's possible to add it via adb #8

Im trying to use this app but nothing happens no crash logs and nothing how did you get this BLUETOOTH PRIVILEGED issue?

it is working now for you?

happens during pairing because setPairingConfirmation(true) requires BLUETOOTH PRIVILEGED.
Even after granting the permission by installing as a system app, pairing fails #1
