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.

Thx @Hung

I should have said that the only interface available on the example I have in mind is BLE. I was thinking that I could avoid custom apps for this (at least for a quick prototype).

(Apart from DFU, I don't think there's an off-the-shelf app for file transfer.)

My latest thought is to attach an SD card and use FDS to save the data to flash. This is a little messy (wires etc) but will do if my first suggestion is too hard.
