I have the same need as the OP for either a Star Topology over Shockburst or BLE Mesh (TBD).

Is there a Zephyr sample for wireless time sync?

Hi Daniel,

I think it wont be that hard to change the behavior to broadcast the same data that we send in the notifications. The challenge here is to configure the broadcast data same as the notification data. Maybe the adv data size is too small? The author of that module and blog is away on parental leave so I cannot get more insights into it easily either. But in short, the challenge seems to fir the notification data in adv data and do start advertiser and send notification at the same configured time interval.
