I am running Ubuntu 16.04 on a Dell Precision 5510 Laptop and it has integrated bluetooth. Whenever I toggle on Bluetooth I get the same error: Jun 22 10:45:19 drhorrible colord-sane: [bjnp] udp_command: ERROR - no data received Jun 22 10:45:19 drhorrible colord-sane: [bjnp] bjnp_init_device_structure: Cannot read mac address, skipping this scanner Jun 22 10:45:26 drhorrible systemd[1]: Starting Load/Save RF Kill Switch Status...
