Call pstorage related functions from BLE stack handler

[ppatierno]

Hi,

just to know ... is it possible to call pstorage related functions inside a BLE stack event handler ? I'm facing with Hard Fault and I have the doubt that it's related to this.

In my main.c I have an event handler called when the app receive data on BLE (ex. some bytes from a smartphone). Inside this event handler I call pstorage related functions (like clear, store, ...).

Is this scenario provided ? Or I need to have another task to call pstorage related functions that is enabled when data arrive in the BLE event handler ?

Thanks, Paolo

Hi ppatierno

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

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.
