`Thank you for the guidance! I have a follow-up question: Currently, the device is always advertising. The device sets a flag every five minutes in the advertising packet (as shown in the attached images). My idea is to connect in the background only when the flag is 1 and perform data collection for about 15 seconds. Would this approach be a recommended practice within the Core Bluetooth framework, or is there a better way to handle this scenario? Thank you for your support!
