How to do pstorage store after advertising

[michaeld]

Hello,

I try to perform an pstorage store action after I'm done advertising just beform the devices goes in system OFF mode. Pstorage works fine before I start advertising but when I have started advertising the pstorage store doesn't get it's callback anymore.

Now I read in a couple of questions you can't perform a store action on a advertising event because the callback will not be received.

My question is how or where can I do a store action when the devices goes into IDLE mode/stops advertising. I tried triggering it on a timer, putting it in the scheduler I'm kind of out of options.

Thank you for your answer! I checked and my device isn't advertising when I try to do the pstorage update just before system goes in system_off mode. Because this is triggered when device is in IDLE and not advertising. On start-up before advertising is started the pstorage update works fine but after it doesn't.

And I don't get why it is not getting the callback.

This is my code:

Init Function:

void livit_pstorage_init(void)
{
uint32_t               err_code;

pstorage_module_param_t param;
param.block_size  = BLOCKS;
param.block_count = 1;
param.cb          = livit_pstorage_cb_handler;

err_code = pstorage_init();
APP_ERROR_CHECK(err_code);
err_code = pstorage_register(&param, &base_handle);
APP_ERROR_CHECK(err_code);	
}

Handler:

static void livit_pstorage_cb_handler(pstorage_handle_t * p_handle,
                               uint8_t             op_code,
                               uint32_t            result,
                               uint8_t           * p_data,
                               uint32_t            data_len)
{
pstorage_flag = 0;
}

Update Function:

void livit_pstorage_update(void)
{
pstorage_handle_t       block_handle;
uint8_t 								index;
uint32_t               	err_code;
uint16_t								i = 0;
uint8_t									k = 0;

__align(4) uint8_t 		  pstorage_data[BLOCKS];

pstorage_data[i++] = m_first_boot;

pstorage_data[i++] = m_config.toggle_settings;
pstorage_data[i++] = m_config.step_ths;
pstorage_data[i++] = m_config.step_debounce;
pstorage_data[i++] = m_config.wear_time_ths;
pstorage_data[i++] = m_config.amount_sync_days;
pstorage_data[i++] = m_config.amount_of_filled_entries;
    ....... (deleded some code for better overview)

index = 0; //we will write to the second block
err_code = pstorage_block_identifier_get(&base_handle, index,&block_handle);
APP_ERROR_CHECK(err_code);

err_code = pstorage_store(&block_handle, pstorage_data, BLOCKS,0);
APP_ERROR_CHECK(err_code);

}

Waiting for callback:

void pstorage_write_alldata(void)
{	
pstorage_flag = 1;	
livit_pstorage_update(); //Note if you use livit_pstorage_update, you don't have to erase before storing

while(pstorage_flag) 
{ 
	power_manage();
}   
}

SOLUTION: Call the write function in the main by checking the advertising status.

have you added this below code

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

this is needed for your callback to be triggered
