Therefore, if you want to add one or more modules that needs to use flash, you should configure PSTORAGE_MAX_APPLICATIONS according to your requirement.</p> <p>If you look at alert notification example that also requires persistent data storage of bonded ANS serves, it uses a PSTORAGE_MAX_APPLICATIONS of 3, 2 for bond manager and for ANS client. Hope this helps!</p><div style="clear:both;"></div>
