Hi there,

What FDS backend are you using?

Update3: The problem is directly related to enabling the soft device handling, this cause that fds events dont execute. I just start the sdh without advertising using the command nrf_sdh_enable_request();, and then initialize the fds and the events dont execute. Also trying initializing the ble_stack, (nrf_sdh_ble_enable(&ram_start);) and still dont work. Can annyone have an idea why FDS events only execute when SDH is not enable? Is there another way to store data on flash without FDS? I am ussing "NRF_SDH_DISPATCH_MODEL 0" i dont really know the correct way to use polling or appsh. Also in sdk_config.h i have #define FDS_BACKEND 2, so it should only work with SDH enable right? so it dont have much sense that only work with sdh disabled

Update2: If i add the line "nrf_sdh_disable_request();" right before "fds_record_update", the update performs without problems, but the BLE connection shutdown, and then i have to restart the device to re-enable the BLE and confirm that the "device name" settings was changed with success. So what can i do? I dont want that my program have to disable softdevice and restart everytime i wanna storage some data on flash. Is this a known issue of SDK v16.0.0? Maybe is there a way to dispatch this fds event manually like i did with SDK v12.3.0 with the SoftDevice system event handler?

Update: It seems clearly that is a conflict when the BLE is initialized, in the main routine of the program i first initialize the FDS module and then BLE module, and the fds initialization execute without problem, if i change the order and in first place i init the BLE, and then the FDS, the FDS initialization dont execute the event of write or update.
