When will support for these features (PAwR & Encrypted Advertising Data) be added to the connecting devices (mobile phones and web browsers (Web Bluetooth API) ? How do you ensure both sides can communicate with the latest standard - sorry for simple question but I am pretty new to BLE and how the latest versions are rolled out across every architecture.

I want to know can one synchronized device transmit one or more response packets in one or more response slot per subevent

The Zephyr sample in the NCS v2.4.2 is quite confusing to me in the way that it connects the observer and broadcaster, it seems to have redundancy in it.

I'm wondering if there is a cleaner way to send an AUX_CONNECT_REQ during the subevent and establish a short ACL (would it even be a short ACL?).

Even the official Bluetooth PAwR documentation wasn't clear in my opinion about this. It just briefly mentions AUX_CONNECT_REQ as a part of a subevent packet, that's sent by the broadcaster. and AUX_CONNECT_RSP which is sent from an observer that's "subscribed" to that specific subevent.

Now I'm left to wonder:
1. How does this ACL work, and does it automatically terminate at some point? Or does it become a full-blown BLE ACL connection where they exchange data in an old-fashioned way (services, characteristics)?
2. How to use PDU_ADV_TYPE_AUX_CONNECT_REQ in Zephyr? How to set it for a single subevent at wish?
3. About PAwR in general, multiple observers can subscribe to the same subevent. What if they try to answer during the same response slot? Will there be interference?

If anyone can clear some of these up, that would be awesome!

Do you maybe have some pointers on how to track the bluetooth support from android and apple? I would like to know what hardware/OS supports 5.4, or when. The info I'm coming across on their sites are too vague to determine their commitment/timeline.

When will the samples be available in NCS? I don't see it in 2.3.0 but I do see it in the vanilla zephyr sdk.

The synchronization method looks really interesting to me. Will it be possible to synchronize several nodes on the application layer with this method as well? Would be really cool for the use in a WSN.

Thanks for the overview, seems appealing.

Is the nRF52840 going to support it in future SDK versions?

I would like to create an ESL using PAwR using NCS 2.3.0. There seems to be no sample available yet. Do I just call the functions in nrfxlib?

Nice features
