I have an application that uses FDS and I've recently added to it the peer manager in SDK 12.2.0, which also uses FDS. It turns out that the application data keeps being updated, so every time that happens, a record is deleted in FDS and a new one is allocated and flash pages can't be reused until all their records have been deleted. I managed not running out of flash by adding an extra flash page to FDS so there's always one that can be reused by the garbage collector. Pages sort of keep rolling and each time a new one is used, the oldest one gets freed.
My concern here is that if application data and peer manager share the same FDS space. If I pair a device (let's say I allow pairing only once), then I'll have at least one page that will hold the pairing information and that I'll never be able to reuse. Is that correct?
Also, my application stores a given number of records in FDS. Each record always has exactly the same size and it's only their contents that change. Is it possible to reuse exactly the same flash section, taking into account data size never changes? That way I wouldn't need to worry about reusing flash pages and assigning that extra page to FDS.
