I have a working project with firmware for a NRF51 part in VisualGDB and am now trying to get a working solution for device firmware update over the air using the various sources of information available for getting DFU working with a gcc based toolchain, however whilst I can get the bootloader to advertise, it crashes when trying to upload a firmware with Nordics apps and wondered if anyone here has a working DFU project or notes that you could share?
