Hi Anna,

The Peer Manager uses the FDS module, which then again uses the fstorage module. See the figure here.

The Device Manager uses the pstorage module. The Device Manager was removed in SDK 12, here is the release notes:

** BLE **
- Removed the Device Manager modules. All example applications now use 
  the Peer Manager.
- Removed the pstorage module. All example applications now use the 
  fstorage module.

Thank you so much for the answer. I have another doubt about fstorage and pstorgare. In some example (ble_app_hids_keyboard) use a pstorage, if i understood correctly have the same functionality, but the first is used with peer manager and the second with device manager. Is It correct?

The fs_sys_event_handler() is needed because the peer manager uses flash storage (the fs stands for flash storage). If the peer manager writes to flash, this handler will notify the peer manager that the write is finished.

Advertising doesn't start until all flash events have finished. The ble_advertising_on_sys_evt function tells the advertising module when all flash events are finished, so it can start advertising.
