Apple watch series 8 - Bluetooth Stops Advertising while locked/screen off

Hey everyone,

I recently developed a WatchOS app which includes a peripheral manager that starts advertising when the app is loaded. I've observed that on the Apple Watch Series 8, the Bluetooth advertising stops functioning when the watch is locked/screen off. However, on other series such as Series 7, 6, etc with the latest WatchOS, the app works as expected.

I know that the app doesn't broadcast any of my data while running in the background, nevertheless, the watch still advertises BLE. However, on Series 8, I noticed that no advertising packets are being sent except for the offline finding Find My packets.

I would appreciate any insights or suggestions that could help resolve this issue. Thanks in advance!

I have the same issue. I did however found out that it does actually still broadcast but again with random mac adresses with apparently a different IRK? not sure how to obtain this second IRK.
