I created a app with s110 V7 and want to program the PCA10006 with this app. To get thing working, I need to update the softdevice as well (beacon PCA10006 is shipped with an older version, am I right?). I tried to program the softdevice s110 V7 with the android Master Conrol Panel. As soon as I enter the DFU mode, and select the softdevice from my dropbox, the DFU mode is exited. What went wrong?
