The proper "packet type" for sending (and receiving) relatively large amount of data?

[Erik]

Hello Nordevzone, so far, to the best of my knowledge, you can send data using API call sd_ble_gatts_hvx() with "notification packet" (quotemarks due to my limited knowledge on denomination and denotation of these data packages), as illustrated in the nordic multi-link example.

I'm wondering, is this the only way? Are there better alternatives?

Thanks. Erik

That's the best alternative because it's the only way to get more than one packet of data sent out during a connection event.

There's only really one type of packet, defined down at the link level. The difference isn't in the packet type, it's in the procedure around sending it, whether it's a read, a write an indicate or a notification, each of which goes in a certain direction and does or doesn't require an acknowledgement at the API level (at the LL level all packets are reliably sent and acknowledged).

So you're looking at the notification procedure, not a special notification packet.
