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.

First, you requested 16*100 = 1600 bytes which is more than a page. I hope you have changed

#define PSTORAGE_MAX_APPLICATIONS   2   

Second, I am not big expert in timeslots, but looks like beacon_evt_handler is called with highest priority 0X00, hence you cannot make any sd_flash_xx calls, which means that pstorage does not work in this context. It will hardfault if you try to call any sd_xxx calls at this priority. I am not sure if timeslots can be called with priority less than SVC, i will have to comeback with that information.
