While running these commands, no relevant information is flagged by AppArmor in the logs. This indicates that AppArmor is not denying bluez's ability to execute these commands, but instead bluez is experiencing some sort of problem when it attempts to query the features on the device. Attached is potentially some useful information on the WiFi/BT in this laptop.
