Greetings,My dear Kszaq brother; Do I mean IOCTLS Conditional Access (CI) unit?
Respects...
I'm not sure I understand your question. Beta4a fixes system calls: ioctl - Wikipedia This means that USB tuners were not working at all in beta4 and beta4a fixes this. No new functionality has been added.
However, while I can see and use bluetooth in Android, I'm finding "Bluetooth is disabled" here and I cannot see a way to enable it. If I go into LibreElec settings, I cannot see Bluetooth either.
LibreELEC Settings -> Services -> Scroll down.
