FDS_ERR_NOT_INITIALIZED

[AdélaïdeB]

Hey guys, With the ble_app_exemple, I manage to add the FDS libraries. Unfortunately, when i run the example in Debug, I got error 2 for fds(FDS_ERR_NOT_INITIALIZED). I'm currently working with Nrf52 s132 pca10040 with SDK11 on a custom board. Also, I'm trying to save characteristic data in the flash, that's why I'm using FDS. I'm not sure how to initiate the FDS handler. Plus, i saw some blog talking about flag? I tried to use it but I'm not sure what flags are suppose to do?

Thanks for the help!

Does this example work on your board?

@Kristin : No it's not working on my board:( I took the fds part, copy and paste it in my code, I have the same error(2).

[EDIT]:

I found the function who's returning this error, in fds.c,

static ret_code_t record_find(uint16_t const * const p_file_id, uint16_t const * const p_record_key, fds_record_desc_t * const p_desc, fds_find_token_t * const p_token) { if (!flag_is_set(FDS_FLAG_INITIALIZED)) { return FDS_ERR_NOT_INITIALIZED; }

My guess is, I don't know how to set a flag haha. Can you help me please

Do you successfully receive the event FDS_EVT_INIT in the event handler provided in fds_register()?

[AdélaïdeB]

I'm able to register the event handler but not able to go to the FDS_EVT_INIT in the event handler.

For the FDS events to be forwarded to the FDS module, fs_sys_event_handler() has to be added to sys_evt_dispatch() in main.c:

static void sys_evt_dispatch(uint32_t sys_evt)
{
    fs_sys_event_handler(sys_evt);
    ble_advertising_on_sys_evt(sys_evt);
}

Could you check if a missing fs_sys_event_handler() in sys_evt_dispatch() is the reason for the problem?
