So I have been integrating FDS into a project under SDK13. It's based on an example that Hung updated for SDK12.1. So after init of fds the method fds_test_find_and_delete() is called. However I am having trouble with it not initialising from time to time.
When it gets to the garbage collection call in the snippet below I will get back error 0x2 or Failure to Initialize. Now if you skip this and just go to a read or write call, the same error occurs.
static ret_code_t fds_test_find_and_delete (void)
{
#define FILE_ID 0x1111
#define REC_KEY 0x2222
fds_record_desc_t record_desc;
fds_find_token_t ftok;
ftok.page=0;
ftok.p_addr=NULL;
// Loop and find records with same ID and rec key and mark them as deleted.
while (fds_record_find(FILE_ID, REC_KEY, &record_desc, &ftok) == FDS_SUCCESS)
{
fds_record_delete(&record_desc);
NRF_LOG_INFO("Deleted record ID: %d \r\n",record_desc.record_id);
}
// call the garbage collector to empty them, don't need to do this all the time, this is just for demonstration
ret_code_t ret = fds_gc();
if (ret != FDS_SUCCESS)
{
APP_ERROR_CHECK(ret);
return ret;
}
return NRF_SUCCESS;
}
I have added this to ble_stack_init()
err_code = softdevice_sys_evt_handler_set(sys_evt_dispatch);
APP_ERROR_CHECK(err_code);
And have added this method
static void sys_evt_dispatch(uint32_t sys_evt)
{
fs_sys_event_handler(sys_evt);
ble_advertising_on_sys_evt(sys_evt);
}
I have also enabled the module in sdk_config.h. So I think I have pretty much covered the main reasons for a failure to initialise.
And the odd thing was that when I first enabled it as above it did not work, same error. At one point I added fstorage.h even though I wasn't getting any errors and then it started working. Then while I was experimenting with some write record_chunk.p_data structs it suddenly stopped working again.
What am I missing?
