Data transfer via DFU

[paul_tanner]

My example has an in-flash-memory data file that needs to be updated much more often than the code. I thought of using DFU for this and like it says here..

devzone.nordicsemi.com/.../

.. implementing a new "filetype". Has anyone tried this? Which files in DFU would need to be modified?

I have built my example in SDK12.3 . Would it be worth moving up to a more reset DFU implementation for this?

Thx.

Yes. If using the SD card we'd load it with the file from any machine with a writer and then transfer the card to the board(s) with the nRF52 and SD card socket. We then use a button to tell it to read the file into flash so we can remove the card.

I also like the idea of adapting the DFU app to make it do file transfers. I see the Android sources are here github.com/.../Android-DFU-Library. There's also a cordova library here www.npmjs.com/.../cordova-plugin-nordic-dfu
