Thanks, I'll try digging into fds module, if no result, I'll follow your suggestion.

Handlers (IRQ) should always be small, right? Having said that, why don't you put for example a switch case in your main, like: case BUTTON_PRESSED: // do your FDS stuff, and the variable is set in the handler. Just a thought... :) (round robin with IRQ type of approach)

after several trials, i might figured out what caused this issue, when I called fds write in an timer event handler, the FDS_EVT_WRITE never triggered, even though sd_app_evt_wait() was called, while called in the initialization of the timer, the FDS_EVT_WRITE triggered and data got written to flash, that is the fds write or delete should not be called in an event handler or its sub calls, such as a button event handler. question is, the calls always happen in event handler, how can I do it right?

No no, I don't think so. In our case we couldn't see the prints and we thought the code was not working. Better use breakpoints (if you can).

my nrf_log print to RTT is disabled, will it still cause the trouble?

I put delete, read or write functions right after fds_register() and fds_init(), the events triggered well, while in my application code, FDS_EVT_WRITE won't trigger any more.

What does your FDS code look like? Do you have tried this unofficial FDS example?

Hey @duckduck, have you found a solution yet? I am getting the same case.

Are you checking the returned error codes of your function calls? What is the result that you get with the FDS_EVT_INIT event? Are you using FDS together with Peer Manager or alone?
