change the power loop as

app_sched_execute();
if (NRF_LOG_PROCESS() == false)
{
    if(nrf_sdh_is_enabled())
    {
        power_manage();
    }
    else
    {
        __WFE();
        __SEV();
        __WFE();
    }
}

The problem in my application is fixed by setting #define CLOCK_ENABLED 0 in sdk_config.h to disable nrf_drv_clock, since I found the problem is inside sd_state_evt_handler() in nrf_drv_clock.c as you pointed out.

It seems ANCS client is working well with CLOCK peripheral disabled.

Thank you, Peter.

Yes, softdevice can be disabled by your suggested power management loop with ANCS example. But it still can not work in my application, I'll do more work to locate the problem and go back. Thank you very much.

I was able to reproduce, but I'm not 100% sure what is going on.

But, it doesn't seem like a good idea to have this:

app_sched_execute();
if (NRF_LOG_PROCESS() == false)
{
  power_manage();
}

Because when you are waiting for events, and your timer expires, it will be executed in app_sched_execute() then it will hit power_manager() and you will get an error because the SoftDevice is disabled. What if you do something like:

    app_sched_execute();
    if (NRF_LOG_PROCESS() == false)
    {
        if(nrf_sdh_is_enabled())
        {
            power_manage();
        }
        else
        {
            __WFE();
            __SEV();
            __WFE();
        }
    }

instead?

I'm using ANCS example ble_app_ancs_c, I'm not sure which handler will receive NRF_SDH_EVT_STATE_DISABLE event. But I think nrf_fstorage_sdh_state_handler() should be the handler, since fstorage module is used in ANCS example.

BTW, you can re-produce the problem with ANCS example in SDK 14, just add several codes line as I described above.

Is there any other better code implementation? I just want to disabled softdevice after some time and switch to a proprietary radio stack. Then after some time, enable softdevice again.

Here my problem is, it seems function nrf_sdh_disable_request() can not be run correctly.

It seems you didn't really answer my questions?

I re-edit my question to add more information at the end, please have a look, thanks.

It is stopped? I'm not sure which example you are using, but I look at ble_app_hrs and it seems that the NRF_SDH_EVT_STATE_DISABLED event is sent to sd_state_evt_handler() in nrf_drv_clock.c and nrf_fstorage_sdh_state_handler() in nrf_fstorage_sd.c. Is this the case with your code as well? Are you saying that you are not reaching one of these handlers?
