Can't disable Softdevice in ble_app_uart

[Giang]

Hi all,

I want to disable SD and reinit SD and reinit my services.

I try by ble_app_uart example.

I add code for button, when I press button 1, it disable SD. When I press button 2, it reinit SD and my service.

But when I disable SD and check by funtion nrf_sdh_is_enabled(), RTT print SD still enable. And right away, I receiver Fatal error by timeout of button

This is my code : 

    // Enter main loop.
    for (;;)
    {
        UNUSED_RETURN_VALUE(NRF_LOG_PROCESS());
        if(disable_SD)
        {
            disable_SD = false;
            uint8_t res = 0;
            uint32_t err_code = sd_softdevice_disable();
            APP_ERROR_CHECK(err_code);
            res = nrf_sdh_is_enabled();
            if(res == 1)
            {
                NRF_LOG_INFO("SD is enable");
            }
            else
            {
                NRF_LOG_INFO("SD is disable");
            }  
        }
        idle_state_handle();
    }

Thank !!

Hi,

If softdevice have been enabled through the softdevice handler library with call to nrf_sdh_enable_request(), you should also make sure to disable it using the same API with nrf_sdh_disable_request(). Failing to do so will leave the softdevice handler in the wrong state and give you errors.

Best regards,
Jørgen

Yes, It can disable SD. Then, I can't use button interrupt . So, can you tell me when I disable SD, What is also disable ?

If I want to reinit my services, what  do I need reinit ? 

Thank !!!
