Have you disabled SoftDevice Protection? When programming the S110 softdevice using nRFgo Studio you need to uncheck the "Enable SoftDevice protection". Also, you need to have a recent version of the nRFgo studio application (>1.17) in order for the DFU functionality to work.

  • No it is not unchecked. What is the problem with this protection? – user3428151 Aug 31 '14 at 09:04

    The DFU functionality uses a bootloader which writes to the memory areas protected by this "SoftDevice protection". This is done in order to modify the interrupt vector so that the bootloader is invoked before the application is executed. This way the bootloader can check if the application should run, or if DFU should be executed, for instance by reading the status of a button. – user1493062 Sep 01 '14 at 06:33
