RTC stops after disconnet from Android

[Marcin]

Hi, I am using nrf51822 chip. I am using RTC to generate irq with CC. Everything works fine for IOS and old Android version. New android version makes 2 things when I disconnect:

1. change register of CC[0] value so I changed to generate IRQ from CC[1]:

   void lfclk_config(void) { ret_code_t err_code = nrf_drv_clock_init(NULL); APP_ERROR_CHECK(err_code);

    nrf_drv_clock_lfclk_request();
   

   }

    uint32_t err_code;
   
    //Initialize RTC instance
    err_code = nrf_drv_rtc_init(&rtc, NULL, rtc_handler);
    APP_ERROR_CHECK(err_code);
   
    //Enable tick event & interrupt
    nrf_drv_rtc_tick_enable(&rtc,false);
   
    //Set compare channel to trigger interrupt after COMPARE_COUNTERTIME seconds
   
    err_code = nrf_drv_rtc_cc_set(&rtc,1,P*60*8,true);
    APP_ERROR_CHECK(err_code);
   
    //Power on RTC instance
    nrf_drv_rtc_enable(&rtc);
   

2. stops RTC after disconnect.

I don't have any idea why on IOS works fine but on new Android it doesn't.

Thanks for help in advance.

Sorry but it doesn't make sense that any external BLE device by connecting influences state of nRF5x registers like this. It must be code running on nRF5x chip which causes it, e.g. Soft Device. What SD are you running? What RTC instance are you using, how you initialize it etc.?
