Hi Alfonso, >> if it can not store its LTK, then why doesn't it use a key hierarchy (as defined in the Bluetooth specification) so that it can restore its keys after reboot. If it remembers its Bluetooth address, then it could clearly remember a single master key. >> >> But seriously, if you can remember your BD_ADDR, then you might want to remember your LTK as well. Just a hint here. > > > Thanks for the hint, I wasn't familiar with "key hierarchies". you should really only use them if your device has no persistent storage. If you have a choice, get a device that has persistent storage. Since generating a random LTK for each device (instead of deriving it from a key hierarchy) is of course more secure.
