void ant_hrm_evt_handler ?

[RixtronixLAB]

Dear Members,

I saw this code ,

static void ant_hrm_evt_handler(ant_hrm_profile_t * p_profile, ant_hrm_evt_t event)
{
    nrf_pwr_mgmt_feed();

    switch (event)
    {
        case ANT_HRM_PAGE_0_UPDATED:
            /* fall through */
        case ANT_HRM_PAGE_1_UPDATED:
            /* fall through */
        case ANT_HRM_PAGE_2_UPDATED:
            /* fall through */
        case ANT_HRM_PAGE_3_UPDATED:
            /* fall through */
        case ANT_HRM_PAGE_4_UPDATED:
            NRF_LOG_INFO("Page was updated");
            break;

        default:
            break;
    }
}static void ant_hrm_evt_handler(ant_hrm_profile_t * p_profile, ant_hrm_evt_t event)
{
    nrf_pwr_mgmt_feed();

    switch (event)
    {
        case ANT_HRM_PAGE_0_UPDATED:
            /* fall through */
        case ANT_HRM_PAGE_1_UPDATED:
            /* fall through */
        case ANT_HRM_PAGE_2_UPDATED:
            /* fall through */
        case ANT_HRM_PAGE_3_UPDATED:
            /* fall through */
        case ANT_HRM_PAGE_4_UPDATED:
            NRF_LOG_INFO("Page was updated");
            break;

        default:
            break;
    }
}

If there is no input, how can I handle it and display result = 0 and not shutting down CPU ?

How can I display 0 from this code ?

NRF_LOG_INFO("Heart beat count:                 %u", (unsigned int)p_page_data->beat_count);
    NRF_LOG_INFO("Computed heart rate:              %u",
                 (unsigned int) p_page_data->computed_heart_rate);
    NRF_LOG_INFO("Heart beat event time:            %u.%03us\r\n\n",
                 (unsigned int) ANT_HRM_BEAT_TIME_SEC(p_page_data->beat_time),
                 (unsigned int) ANT_HRM_BEAT_TIME_MSEC(p_page_data->beat_time));

If there's no input, the code above never displayed and CPU shut down by itself,

Thanks

Here's my main function :

    log_init();
    utils_setup();
    softdevice_setup();
    profile_setup();
	
	  create_timers();
	  nrf_pwr_mgmt_feed(); //Function for indicating activity. 
	  
    
   
	  NRF_LOG_FLUSH();
	 
	   
	   ssd1306_init_i2c(SSD1306_CONFIG_SCL_PIN, SSD1306_CONFIG_SDA_PIN);
	   ssd1306_begin(SSD1306_SWITCHCAPVCC, SSD1306_I2C_ADDRESS, false);
	   ssd1306_clear_display(); 
		  
        ssd1306_display();
	      nrf_delay_ms(500);
	      
        ssd1306_draw_circle(SSD1306_LCDWIDTH / 2, SSD1306_LCDHEIGHT / 2, 30, WHITE);
	       nrf_delay_ms(5000);
            ssd1306_display();
	        nrf_delay_ms(1000); 
		
					
    for (;;)
    {
			  nrf_pwr_mgmt_feed(); //Function for indicating activity. 
        
			  app_timer_start(m_repeated_timer_id, APP_TIMER_TICKS(200), NULL);
			  
              nrf_pwr_mgmt_run();
			  nrf_delay_ms(500);

				

    }

comment this out as well ? err_code = ant_state_indicator_channel_opened();

at profile_setup ?
