nrf_dfu_flash just work when wait_for_event function called

[nta_xyz]

Hi,

I am trying to customize the firmware update for my project, everything is fine when I do not define BLE_STACK_SUPPORT_REQD, but when I use this definition I always get the 0x3 (internal error) while I am trying to write into the flash by using the nrf_dfu_flash (nrf_fstorage_write())

I figured out that if I use wait_for_event() function, suddenly all the write and erase operations which are in the queue, executing successfully!, but I do not want to use wait_for_event() because I need to be in a loop condition for getting my customized data and also I need to use the Softdevice.

Could you please let me know, how I can fix this issue?

I am using nRF5_SDK_14.2.0 with S132 Softdevice.

Thank you in advance

Hi,

Not sure if I have a good suggestion other than compare with for instance the working one:
\nRF5_SDK_14.2.0_17b948a\examples\peripheral\flash_fstorage\

The only way I can think of this error occuring is if the flash command is not NRF_FSTORAGE_OP_WRITE or NRF_FSTORAGE_OP_ERASE. Maybe check that the parameters you call when executing the flash operations are static and not changed.

Edit: You can take a look at this case (SDKv15.2, but should be similar):
