Can I do pstorage store whit S120 scan start?

static void ble_evt_dispatch(ble_evt_t * p_ble_evt)
{
    uint32_t           err_code;
    const               ble_gap_evt_t   * p_gap_evt = &p_ble_evt->evt.gap_evt;
    switch (p_ble_evt->header.evt_id)
    {
        case BLE_GAP_EVT_ADV_REPORT:
        {
	      pstorage_handle_t 		flash_handle;	
	      pstorage_block_identifier_get(&flash_base_handle,pstorage_block_id, &flash_handle);
	      err_code = pstorage_store(&flash_handle, (uint8_t * )&tx_data, 32, 0);
	      pstorage_block_id++ ;
        }

yes you can without any problem. The dispatch is happening at SWI2 interrupt priority, just make sure that it is not using APP_PRIORITY_HIGH otherwise the SVC calls within pstorage will cause hardfaults.

update:

ble_app_beacon.zip I have used this app to verify that pstorage event callbacks really occur even if you request them from the event handler.

Thanks, But the pstorage_store cause nothing written in flash. No sys_evt happen, I trace the sys_evt_dispatch() . No faults.

ANd if I move this codes out ble_evt_dispatch（）， then everything OK.

if pstorage_store returned without any errors and if you have registered your event handler for it, then it should work. Can you post the code where you register your event handler. Have you done this

static void sys_evt_dispatch(uint32_t sys_evt)
{
    pstorage_sys_event_handler(sys_evt);
}

// Initialize SoftDevice
SOFTDEVICE_HANDLER_INIT(NRF_CLOCK_LFCLKSRC_XTAL_20_PPM, false);

// Register with the SoftDevice handler module for System events.
err_code = softdevice_sys_evt_handler_set(sys_evt_dispatch);
APP_ERROR_CHECK(err_code);

Yes sure all those INIT codes have been added. And I tried pstorage store work will out of the ble_evt_dispatch(). Like this:

static void weakup_meantimeout_handler(void * p_context)
{
    UNUSED_PARAMETER(p_context);
		pstorage_handle_t 		flash_handle;
		while (rx_count>=32){
						rx_count -= 32 ;
						pstorage_block_identifier_get(&flash_base_handle,pstorage_block_id, &flash_handle);
						if (!(flash_handle.block_id % 1024)) {
								err_code = pstorage_clear(&flash_handle,1024);
							}
						err_code = pstorage_store(&flash_handle, (uint8_t * )&tx_data+rx_count, 32, 0);
						pstorage_block_id++ ;
			}
}

can you please add your main.c file
