Get data from BLE and write to flash memory using pstorage

[trananh]

Hi,

I am having trouble to use flash to store data.

First, I write function and scan beacon, get information from this beacon and save to flash

I use a timer for saving data to flash but it is not work, I always get the error code = 0x00000010. It means "invalid flag". How can I solve this problem?

Thanks and regard

0x00000010 is not 'Invalid Flag', invalid flag is error 10 decimal, that's error 0x10 hex which is 16 decimal which is Bad Memory Address.

That tells you that source_data_1 isn't aligned.

All the other advice about checking error codes is sound, you should check them all every single time. And I doubt there was ever a 'conflict' between pstorage and the beacon_event_handler, you can most likely fix the actual error now you know the difference between decimal and hex and put the code back the way it was.

It seem can not pass this line "while(pstorage_wait_flag) { power_manage(); }"

It can not return to callback function. I tried to stop scan beacon function before pstorage but still not work

for (;;)

{
		if (flash_ready == true)
		{
			app_beacon_scanner_stop();
    //Get block identifiers
	    retval = pstorage_block_identifier_get(&master_handle, temp, &block_0_handle);
	    APP_ERROR_CHECK(retval);		
	    retval = pstorage_clear(&block_0_handle, 16);                   //Clear first registered page. A pstorage_clear command must operate within a single page
	    APP_ERROR_CHECK(retval);		
	    pstorage_wait_handle = block_0_handle.block_id;            //Specify which pstorage handle to wait for 

	    pstorage_wait_flag = 1; 
	    retval = pstorage_store(&block_0_handle, bufferCheck, 16, 0);
      APP_ERROR_CHECK(retval);	 
	    while(pstorage_wait_flag) { power_manage(); }              //Sleep until store operation is finished.
	    nrf_delay_ms(100);
	    retval = pstorage_load(dest_data_1, &block_0_handle, 16, 0);			 //Read from flash, only one block is allowed for each pstorage_load command
	    APP_ERROR_CHECK(retval);
	    nrf_delay_ms(100);
		  temp++;
			flash_ready = false;
			app_beacon_scanner_start();
		 }
		 power_manage();
}
