(side note : it would have been handy if the migration guide mentioned that the advertising timeout configs have changed from seconds to 10's of ms)
It seems to have become harder to dynamically update the advertising packet in SDK15. In SDK14, using ble_advertising, I could just update the manufacturer data used by my instance of ble_advertising_t and call ble_advdata_set and be done. Then whenever ble_advertising did something later, it would continue with the latest data (eg auto restart advertising, change speed etc). Advertising would not be restarted and if you use fast and slow advertising, then that timing and transition would not be affected if you changed the manufacturer data.
Now, we need to use sd_ble_gap_adv_set_configure instead of ble_advdata_set, but the new call wont allow changing the encoded data contents and using the same buffer. You need to provide a new buffer if its busy advertising. Providing a new long lived buffer for each update causes many other issues. One way to deal with this is to stop and restart advertising with the same but updated buffer. But that affects the fast to slow advertising timing and transitions : say you update the data every 1 minute, and your fast advertising goes slow after 2 minutes, then you'll always be in fast mode.
Is there an easy and minimally impactful way to update just the manufacturer data in SDK15 ?
