Can we use DFU with our custom iPhone App as the DFU Controller (source of the upgrade binary)?

[riceman0]

Hello, a question about this link:

https://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.sdk5.v15.0.0%2Flib_bootloader_dfu_process.html

which says

"As the DFU controller, you can use the following Nordic tools: 

nrfutil (version 2.2.0 or later), 

nRF Connect for Desktop, 

Nordic's mobile apps, such as nRF Connect for Mobile."

Does this mean that we *have* to use one of these three things, and that cant use our custom original iPhone App as the DFU controller, to upgrade our nordic peripheral?

Or, if we can use our iPhone App, is there some library or support we need to incorporate into our App?  Or do we just need to conform to a certain profile or protocol?

Thanks.

Hi,

You are free to use your own app as the DFU controller. We supply DFU libraries for iOS as well as android to make that easy for you. See iOS DFU Library and Android DFU Library.
