Thank you for your answer. With the nRF Toolbox it is working. The second part of my question is also answerd. The Toolbox app connects to the device to check if the DFU service is existant.

Maybe a suggestion for upcoming Toolbox releases. The disconnect when the Application mode was left and the bootloader entered should be suppressed by the App. Otherwise it is a bit irritating for normal users.

Hi Adrian, IOS app nRF Loader is no more supported by Nordic Semiconductor. In order to use DFU in SDK 6.1 you have to use our app nRF Toolbox. It is available on App store. It contains 8 BLE profile including DFU. You can use DFU part of the app in order to upload firmware.

For 1) I got it to work by changing this

#define DFUCONTROLLER_DESIRED_NOTIFICATION_STEPS 30

in the DFUController.m

The reason to this is the DFU code use 600 bytes buffer. So we can only send 600 bytes per interval. Only 20 bytes can be send at a time so .

DFUCONTROLLER_DESIRED_NOTIFICATION_STEPS * DFUCONTROLLER_MAX_PACKET_SIZE must be equal to 600 bytes
