how to use fds_write() fds_read() SDK13

[Mikhail]

I try to implement this library to my code.

uint32_t settings_set_erase_flag(int32_t flag)
{
	uint32_t err_code = fds_write(flag, ERASE_BOND_FLAG);
	return err_code;
}

int32_t settings_get_erase_flag(void)
{
int32_t flag;
		uint32_t err_code = fds_read(&flag, ERASE_BOND_FLAG);
		if(err_code != FDS_SUCCESS)
			return 0x33;
		else
			return flag;
}

But when I want to read this value, I always get 0x33

How can I correct usage this library?

The example ble_app_hrs-fds-test-github.zip in this answer shows how to use FDS wiht SDK 12.2. It should be quite easy to copy the FDS part to a SDK 13 example and make it work.

I use same code base on the your code:

static ret_code_t fds_read(int32_t * sens, uint16_t key)
{


fds_flash_record_t  flash_record;
	fds_record_desc_t   record_desc;		
	uint32_t 						err_code;
	
	

while(fds_is_existed_record(&record_desc, key))
		{
			if((err_code = fds_record_open(&record_desc, &flash_record)) != FDS_SUCCESS)				
				return err_code;						

			* sens = * (int32_t *)flash_record.p_data;

			return fds_record_close(&record_desc);			
	

}
	return FDS_ERR_NOT_FOUND;		

}

Which function inside fds_read() return 0x33?

[Mikhail]

del 11111111

If You see first post, I return 0x33 if in the function

settings_get_erase_flag()

I call

fds_read()

if(err_code != FDS_SUCCESS)
        return 0x33;
