how pstorage_register insure same address between startup?

[julian]

it register a handler, what about restart and run pstorage_register again, how it insure everytime we get the same address for our content in the flash? before pstorage_register, we use flash_io, which we know the address, so no problem to access the right place in flash, so pstorage_register ensures the correct address by order of calling pstorage_register?

and PSTORAGE_MAX_APPLICATIONS, seems not for application, but defines how many pages we use? is there a max number of pages we can use? how to find out this number for nrf51822-xxaa-s110? as I recalled, 16k for softdevice, and size of app(how to find the size of app in the device?) anything else will take space?

Thanks!

I just want to add one very important point here (because it not obvious at first) but any pending PStorage calls will not complete unless you return from:

ble_evt_dispatch();

or whichever function you registered with softdevice_ble_evt_handler_set().
