https://devzone.nordicsemi.com/f/nordic-q-a/9314/call-pstorage-related-functions-from-ble-stack-handlerHi, just to know ... is it possible to call pstorage related functions inside a BLE stack event handler ? I&#39;m facing with Hard Fault and I have the doubt that it&#39;s related to this. In my main.c I have an event handler called when the app receiveen-USTelligent Community 13Fri, 25 Sep 2015 08:53:58 GMThttps://devzone.nordicsemi.com/thread/34380?ContentTypeID=1Fri, 25 Sep 2015 08:53:58 GMT137ad170-7792-4731-bb38-c0d22fbe4515:557eb52d-1841-40ff-b3eb-cb0e4b8e59b6ppatierno<p>I solved the problem as I explained in the question. Using an asynchronous task (with an app_timer) to call pstorage related function and not inside BLE handler. Calling pstorage operation from BLE handler always end in an Hard Fault.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/34379?ContentTypeID=1Thu, 24 Sep 2015 16:21:45 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d06ffdcc-8bb0-435b-9c96-04a2d26dd380Stefan Birnir Sverrisson<p>Hi ppatierno</p> <p>It should work to call pstorage operation from a BLE interrupt handler. However, it is not a good practice to process much code in an interrupt handler, as all other BLE callbacks are blocked when processing the event handler</p><div style="clear:both;"></div>
