4.4 and bluetooth ...on a Pi2 ?? - DRONE7 - 12-12-2018
Having odd problems with power dropping on a Pi2 and 4.4 release.....
looking in logs I find....
[ 574.011229] Bluetooth: HCI device and connection manager initialized
[ 574.011262] Bluetooth: HCI socket layer initialized
[ 574.011275] Bluetooth: L2CAP socket layer initialized
[ 574.011315] Bluetooth: SCO socket layer initialized
How...what...this is a Pi2... no bluetooth hardware either internal or externally so why is it starting bluetooth services..?
I've never and never will use bluetooth so how can I blacklist/prevent these services.....

Those look harmless to me.
Bluetooth never started (OFF in Audio config), Pi-2B
Code:
pi@rp4:~ $ hciconfig
pi@rp4:~ $ sudo ls /var/lib/bluetooth
ls: cannot access '/var/lib/bluetooth': No such file or directoryBluetooth running (ON in Audio config), Pi-Zero W
Code:
pi@rp2:~ $ hciconfig
