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

Hello,

The ANT channel state indicator module makes the application enter SYSTEM OFF mode (i.e. deep sleep) when it receives the EVENT_CHANNEL_CLOSED event. If you want to avoid this you can remove initialization of this module in addition to removing the source file (ant_state_indicator.c) from your project.

How can I display 0 from this code ?

 Sorry, but not sure I understand what you mean by this. Can't your app just display '0' if it hasn't received any ANT_HRM_PAGE_X_UPDATED events?

Hi Vidar,

Thanks for the reply,

What I mean from "How can I display 0 from this code ?"

If there is no input from sensor, how can I display the value of the sensor = 0, because it doesn't have event yet ? and result is being displayed if there's event.

Thanks

do you mean by commenting out this :

err_code = ant_state_indicator_init(m_ant_hrm.channel_number, HRM_DISP_CHANNEL_TYPE);
    APP_ERROR_CHECK(err_code);

at

static void utils_setup(void)

How can I change the setting of ant_state_indicator for example turn it off after 1 hour ? thanks

The cadence and speed sensor stopped transmitting now, but

I still got :

nfo> app: Computed speed value:                         2 kph
                

nfo> app: Computed cadence value:                       89 rpms
              

nfo> ant_hrm: HRM RX Page Number: 4
                                          

nfo> ant_hrm_page_0: Computed heart rate Rixtronix:              63
          

nfo> ant_hrm_page_0: Heart beat count:                 196
                   

nfo> ant_hrm_page_0: Computed heart rate:              63
                    

nfo> ant_hrm_page_0: Heart beat event time:            18.724s
     

it supposed to be 0 on speed and cadence, any ideas ?

Thanks

When it's idle for more than 10 minutes and I give input from the sensor, it stays idle, how can I rectify it ? thanks
