Hi,

I don't have much experience with app development myself, and generally this forum is for nRF development. I suggest you refer to Apple's documentation and Apple developer forums for iOS development questions.

Hi,

Data Length Extension (DLE) is a concept in connections and have nothing to do with advertising.

I agree that ADV_EXT_IND is not indicated directly anywhere. But, looking at this document, I see that it is actually recomends using "Data Packet Length Extension". Moreover, they mention that this is the recommended approach for both performance and battery life:

Chapter 49.7:

"Data Packet Length Extension increases the maximum data length from 27 to 251. Using larger per-packet data lengths improves radio efficiency, greatly increasing application data rates and boosting battery life. See the Bluetooth 5.0 specification, Volume 6, Part B, Section 4.6.6 for details.

Accessories should support Data Packet Length Extension for best performance with devices.

iOS devices and Mac computers operating as the Central will negotiate optimal data packet lengths based on various factors, such as connection event length, system topology, and protocol.

Hi,

There is no suport for sending extended advertising packets (of any form) with nRF Connect for iOS. Regarding APIs there may be some support (there is for scanning, though apple does not recomend the use of extended advertisign in their Accessory Design Guidelines for Apple Devices as it is not one of the recomended advertising types).
