We even powered off the paired device, but the system still be waken up by advertising packets from other random BT4 devices. I got some questions for you and would like to figure out a feasible solution for the issue. 1. Do you have any idea about who decide to wake up the system when the advertising packet is received? Firmware or driver? 2. Do you know how windows handle this? Does the advertising packet wake up windows? 3. Is there any drawback if we remove 'HCI_AUTO_CONN_ALWAYS' flag when suspending? Thanks. -- You are receiving this mail because: You are the assignee for the bug.
