fstorage not initializing properly in my app

[erltot]

I want to store two floats and one 8 character string in fstorage.

I solved it by using 4 uint32 types stored in flash, I got it working in the ble_app_template example, but when I try to implement the same in my own app, the callback is not run, leaving my app to wait for event forever..

I noticed that the address is different in the two, in the ble_app_template it's stored in 0x79000, while in my app it's stored in 0x7C000. My app is built on ble_peripheral/ble_app_uart

SDK: 12.2

Any insight?

Did you add fs_sys_event_handler(sys_evt) to sys_evt_dispatch () in main.c?

[erltot]

Nope!

Added

static void sys_evt_dispatch(uint32_t sys_evt)
{
    // Dispatch the system event to the fstorage module, where it will be
    // dispatched to the Flash Data Storage (FDS) module.
    fs_sys_event_handler(sys_evt);

    // Dispatch to the Advertising module last, since it will check if there are any
    // pending flash operations in fstorage. Let fstorage process system events first,
    // so that it can report correctly to the Advertising module.
    ble_advertising_on_sys_evt(sys_evt);
}

and

static void ble_stack_init(void){
.....
// Register with the SoftDevice handler module for BLE events.
err_code = softdevice_sys_evt_handler_set(sys_evt_dispatch);
APP_ERROR_CHECK(err_code);
}

Now it seems to work :) Thank you

Good that it is working :) This answer explains why fs_sys_event_handler() should be added to sys_evt_dispatch().
