Hi Alain, > I suspect we'd want bluetoothd to have a configuration that can enforce a more secure posture. > > Unfortunately when the command isn't supported, the platform is left between a rock and hard place... There isn't much we can do but to block the use of Bluetooth if the platform requires a more secure posture. so if the BR/EDR part is not up to the policy that the host requires, we could still configure the LE part. BlueZ is set up in this way that you can run a dual-mode controller as just a LE controller. I would also opt for the kernel just tells us what options it have. Then at least we can provide some feedback to the end-user on why Bluetooth is not available or why only selected features are available. Regards Marcel
