I have used the Programmer previously with success. I am attempting to program the Dongle (10059) with a slightly modified version of ble_nusc_usb_dongle. Although it claims to have completed successfully in 14 seconds, it halts with an error message in red in the log. Also I note that the memory map shown in the Programmer does not change.
