FDS not working after SD initialize

[Maidu]

HI, I have nrf52832 and I am using latest SDK 14.2.0. 

I am using FDS and the problem is that before setting up BLE fds_record_write works fine but after setting up BLE all data using fds_record_write goes to dirty records. My ble part is just simple central what scanns advertisements and creates connectioin. Here is my main code.

ret_code_t ret;

ret = NRF_LOG_INIT(NULL);
APP_ERROR_CHECK(ret);

NRF_LOG_DEFAULT_BACKENDS_INIT();

ret = app_timer_init();
APP_ERROR_CHECK(ret);

NRF_LOG_INFO("RUN\r\n");

//INIT FLASH
fds_register(fds_evt_handler);

NRF_LOG_INFO("Initializing fds...");

ret = fds_init();
APP_ERROR_CHECK(ret);

wait_for_fds_ready();

fds_stat_t stat = {0};

ret = fds_stat(&stat);
APP_ERROR_CHECK(ret);

NRF_LOG_INFO("Found %d valid records.", stat.valid_records);
NRF_LOG_INFO("Found %d dirty records (ready to be garbage collected).", stat.dirty_records);

fds_gc();

//When I call here fds_record_write it works fine

ble_init();

//When I call here fds_record_write it goes to dirty records

Do you check all the returns from the FDS functions?

Attached is an example using the FDS from the ble_app_uart example. Check the UART log to see if it works. At least from here, I can start the FDS module after ble_stack_init();

Hi, that looks working. I can take it as reference to my project. Thanks.
