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.
