I'm having an issue with secure BLE pairing, and once the problem shows up, it will not go away until I reprogram the SoftDevice. It persists through resets, so it must be due to data in flash. After having made a couple of "before and after" hex readouts, I notice that a bunch of data shows up in flash, just after an array of application data that I need to be persistent and that I've placed far away from the actual SD and application code sections. This is the only thing that appears different between the "before" and "after", so what is this stuff?
