Integrate OTA DFU into iOS or Android app?

[JohnBrown]

Is it possible to integrate the master end of the OTA DFU process into an iOS or Android app? The scenario would be that the iDevice or Android downloads a new version of the app, which comes with an image of the new nRF5x code, which is then transferred to the nRF device. This is, after all, the usual way of updating firmware in things such as your very own PCA10000, for example. It's hard for me to imagine asking an end user to download rRF toolbox and using that...

Why would it be impossible? OTA DFU is normal GATT-based transmission. You just have to do some writes, receive some notifications and just handle it.

This may be useful to implement it. It may differ if you use bootloader from another SDK version.

Thanks. I didn't say it would be impossible, just asking. I guess I should have asked whether the Nordic OTA DFU protocol was documented and available.

[Wojtek]

We did implement that basing on that document :)

OK, thanks.
