FDS event handler is not occur.

[moon.kim]

Hi,

I am developing using nRF52820 / SDK 17.0.2

In order to store data in FDS, the handlers were registered and initialized as follows.

void BLE_Init(void)
{		
	ble_stack_init();
	gap_params_init();
	gatt_init();
	advertising_init();
	services_init();
	conn_params_init();
	peer_manager_init();
	
	return;
}

static void FDS_Event_handler( fds_evt_t const * p_evt )
{
	SEGGER_RTT_printf(0, "FDS_Event_handler id : %d / result : %d\n", p_evt->id, p_evt->result);
    switch (p_evt->id)
    {
        case FDS_EVT_INIT:
		case FDS_EVT_GC:
		case FDS_EVT_WRITE:
		case FDS_EVT_DEL_RECORD:
		case FDS_EVT_UPDATE:
        break;
    }
}

int main( void )
{
	fds_record_desc_t desc = {0};
	fds_find_token_t  tok  = {0};
	fds_record_t RecordData;

	RecordData.file_id = DATA_FILE_ID;
	RecordData.key = DEFAULT_RKEY;
	RecordData.data.p_data = pData;
	RecordData.data.length_words = DATA_FILE_SIZE;
	
    .....
    BLE_Init();
    fds_register(FDS_Event_handler); 
    
    .....
    
    if( fds_record_find( RecordData.file_id, RecordData.key, &desc, &tok ) == NRF_SUCCESS )
	{		
		if( fds_record_update( &desc, &RecordData ) == FDS_ERR_NO_SPACE_IN_FLASH )
		{			
			fds_gc();					// run garbage collection
			fds_record_update ( &desc, &RecordData );			
		}
	}
    .....
}

FDS_Event_handler does not occur after fds_record_update().

Why the event is not occurring?

An event occurs when garbage collection is executed, but an event does not occur when FDS update.

And how can I check that the update is completed in queue process after the update?

I would like to know that the FDS update is complete without using a event handler if possible.

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

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