I guess it has the same or higher priority than the Softdevice events, so the wait loop ends up blocking the FDS callback forever. Yes, please try removing the wait function.

Yet I am not considering removing this loop. Could this loop be a problem?

Yes, Do not use the scheduler. Instead, it calls the update on an interrupt.

Yes, After executing fds_record_update(), it waits until FDS_Event_handler() occurs.

This is to check if the FDS update is complete.

I see the NRF_EVT_FLASH_OPERATION_SUCCESS events are reported several times when the PM updates data in FDS, but not when you update fds from main(). Does logging stop after the "record update error code : 0x0" line?

This is the log that added the FDS update error code.

FDS update is executed even at boot time, but in that case, FDS handler occurs normally.

You should register all FDS users before fds_init() is called from pm_init(), but I don't think that is related to the problem. From the snippet you posted I noticed that you are not doing any error checks. Can you check if fds_record_update() is being called, and if it is returning an error code or not?

Hi.

Sorry for the late reply

I tested it as you told me.

Softdevice event did not occur after FDS update was executed.

I run an FDS update to store the Peer ID in FDS after pairing.

But the FDS event handler(fds_evt_handler) I added doesn't executed.

Is it because of the peer manager?

Hi,

Any chance you could upload a minimal version of your project here so I can try to debug it? I don't see any obvious problems in the code you have posted.

A suggestion if you want to try debug this yourself is to place a breakpoint inside nrf_sdh_soc.c::nrf_sdh_soc_evts_poll() after sd_evt_get() to check if you receive any Softdevice flash events at all.

I initialize the peer manager as in the example code.
It was confirmed that pds_init() was called in pm_init().

So, fds_init() was not executed again, and only event handlers were registered.

ret_code_t pds_init()
{
    ret_code_t ret;

    // Check for re-initialization if debugging.
    NRF_PM_DEBUG_CHECK(!m_module_initialized);

    ret = fds_register(fds_evt_handler);
    if (ret != NRF_SUCCESS)
    {
        NRF_LOG_ERROR("Could not initialize flash storage. fds_register() returned 0x%x.", ret);
        return NRF_ERROR_INTERNAL;
    }

    ret = fds_init();
    if (ret != NRF_SUCCESS)
    {
        NRF_LOG_ERROR("Could not initialize flash storage. fds_init() returned 0x%x.", ret);
        return NRF_ERROR_STORAGE_FULL;
    }

    peer_id_init();
    peer_ids_load();

    m_module_initialized = true;

    return NRF_SUCCESS;
}

So wait for FDS init & fds_state(&state);

Have you done that?

Actually fds_gc() will trigger the handle id,but I am not sure your code for init & pre-procedure.

But fds_record_update() will also trigger one, if execute write_enqueue();

moon.kim — Tue, 15 Dec 2020 08:48:45 GMT

I know that fds_init() is done in peer_manager_init()

RE: FDS event handler is not occur.

Henry_Chou — Tue, 15 Dec 2020 08:47:02 GMT

Have ever done the fds_init() in your code? It seems like no initialization FDS.
