FDS events are not receiving in freertos project

That is ok..

But i want to immediately read after write... And read should be done only after i receive write event..

But if i'm waiting in while loop for write event to be successful, softdevice task wont run parallely and events wont receive..

How do i do that? How do i read immediately after write?

Please help..

If possible, please help me with an example..

You will not receive any events until you start the Freertos scheduler. Maybe you can do the write from a task instead?

no error with write function.

I see that if i dont wait for write event on while loop, i am receiving write event.

But i have to read the data back as soon as i write data..

In that case, what has to be done?

Hi,

Please confirm if the write function is returning an error code or not.

Hi Vidar,

Yes after removing it in main(), fds initialize event received.

But when i added fds write function after nrf_sdh_freertos_init() function, i am still not receiving fds_write event.

Thanks. The problem is that you're waiting inside wait_for_fds_ready() before the BLE task has been started, so the Softdevice event queue is not being processed. Please try to comment this function in main().

Result after commenting the wait function:

Hi,

Are you able to share your project here so I can try to debug it?

devzone.nordicsemi.com/.../82252.main.cHi Vidar,

I kept a breakpoint in nrf_sdh_soc_evts_poll() function.

It never reaches the breakpoint.

sharing main.c for reference.

Hi,

Please make sure you have included the nrf_sdh_soc.c (nrf_sdh_soc component) in your project, and if you already have, place a breakpoint in nrf_sdh_soc_evts_poll() to see if it ever receives any SoC events from the Softdevice (NRF_SOC_EVTS)

Thanks,

Vidar
