Address resolution is also done by the Host. This requires Host intervention every time an advertisement packet with an RPA is received. In Bluetooth 4.2(LE Privacy 1.2), the Resolving List is maintained in the Controller. Since the Controller resolves the private address, the Host does not need to wake up in devices where the Host is implemented using a separate CPU. This lowers overall power consumption. Having said that, Intel controller does support LE Privacy v1.2 feature. However Linux kernel need to enable to make use of the Link Layer privacy to avoid this kind of issues. This is generic problem/behavior observed on other vendors BT controller as well that does not support LE privacy 1.2 feature. We highly recommend to enable LE privacy 1.2 to solve the problem. -- You are receiving this mail because: You are the assignee for the bug.
