Bluetooth: Set different event mask for LE-only controllers
In case of a Low Energy only controller it makes no sense to configure the full BR/EDR event mask. It will just enable events that can not be send anyway and there is no guarantee that such a controller will accept this value. Use event mask 0x90 0xe8 0x04 0x02 0x00 0x80 0x00 0x20 for LE-only controllers which enables the following events: Disconnection Complete Encryption Change Read Remote Version Information Complete Command Complete Command Status Hardware Error Number of Completed Packets Data Buffer Overflow Encryption Key Refresh Complete LE Meta This is according to Core Specification, Part E, Section 3.
