Once the system has paired with BT4 devices(disconnected), the system will be waken up randomly from S3/s2idle while receiving advertising packet from any random BT4 devices in the environment which are even not paired/connected. By removing all previously paired BT4 devices(disconnected) from BT menu can fix this issue. The advertising packet could be none connectable undirected or connectable undirected. And the BT4 devices we found can reproduce this issue are 1. Microsoft Surface 1678 2. Logitech K375s 3.
