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...
