help
If the period value is non-zero, the controller will periodically clear the device information
stored in the scan duuplicate filter. If it is 0, the scan duuplicate filter will not be cleared
until the scanning is disabled. Duplicate advertisements for this period should not be sent to the
Host in advertising report events.
There are two scenarios where the ADV packet will be repeatedly reported:
1. The duplicate scan cache is full, the controller will delete the oldest device information and
add new device information.
2. When the refresh period is up, the controller will clear all device information and start filtering
again.
