* Switch to bootloader/DFU mode by writing to the control point of the DFU Service.
* The DFU Controller is not responsible for disconnecting from the application (DFU Target) after the write.
* The application (DFU Target) will issue a GAP Disconnect and reset into Bootloader/DFU mode.
* The application (DFU Target) will issue a GAP Disconnect and reset into bootloader/DFU mode.
