extenal observer for a periodic adverttising 1 to 4 network

[novello]

There is a way to make an observer to verify how the subnetwork work: periodic advertising with response ? 

Thanks

Hi,

Yes, there is. I would suggest you to take a look at our PAwR synchronization (observer) sample in nRF Connect SDK to see how the PAwR subnetwork works. The sample pair is periodic_sync_rsp (observer) which is to be used with periodic_adv_rsp (advertiser). The observer sample:

1) Starts scanning and creates a periodic advertising sync with the advertiser with bt_le_per_adv_sync_create().

2) After the sync has been established, it uses bt_le_per_adv_sync_subevent() to choose subevents to listen to.

3) For each PAwR event, the observer receives a callback with:

• which subevent it came from
• the data from the advertiser. In the same callback, it can send a response back in a chosen response slot by using PAwR response APIs. 

I would recommend you to see our PAwR guide. For API for creating and managing periodic advertising and sync objects, take a look at Zephyr BT GAP.
