Changing advertisement data while advertising

[mst]

I try to achieve something similar to IBeacon where data is pushed to any device listening, but where the data is changing over time. Is it possible to (frequently) change the advertisement data (such as the Manufacturer specific data) after a BLE peripheral starts advertisement? Or do I need that explicitly stop and start advertising with new data, or think of another solution to achieve pushing data to BLE scanners without setting up a connection?

You can change advertising data at any time, using sd_ble_gap_adv_data_set(), or as exposed through the ble_advdata module of the SDK, ble_advdata_set().

I tried to use either but no luck, do you need to stop advertising -> change the data using ble_advdata_set -> start advertising again? The way I did was to expose ble_advdata_set in my while loop but again I did not see any data updated?
