EVENT_CHANNEL_CLOSED ?

Hi Simon,

I made this function :

/**@brief Initialize ant search Rixtronix LAB 8Apr22
 */
 static void ant_search_initialize()
 {
	 ret_code_t err_code;
	  const ant_search_config_t bs_search_config =
    {
        .channel_number        = ANT_BS_CHANNEL_NUMBER,
        .low_priority_timeout  = ANT_LOW_PRIORITY_TIMEOUT_DISABLE,
        .high_priority_timeout = ANT_HIGH_PRIORITY_SEARCH_DISABLE,
        .search_sharing_cycles = ANT_SEARCH_SHARING_CYCLES_DISABLE,
        .search_priority       = ANT_SEARCH_PRIORITY_DEFAULT,
        .waveform              = ANT_WAVEFORM_DEFAULT,
    };
		 err_code = ant_search_init(&bs_search_config);
    APP_ERROR_CHECK(err_code);
 }	 

Where can I call it ?

before main loop and after channell open ?

Hi

What SDK version and SoftDevice version are you using specifically? At least in nRF5_SDK v17.1.0 ant_search_init() is defined in ant_search_config.c/.h located in ...\SDK_FOLDER\components\ant\ant_search_config\

I would not recommend making the function yourself as it uses some ANT and SoftDevice specific functions.

Best regards,

Hi Simon,

Thanks for the reply,

I use SDK 17.02 and softdevice 340,

I have run the function, but when I lost contact with ANT sensor, and I left the receiver for few minutes,

return to the receiver,

it's not doing background scanning, how can I activate that ?

Hi

Unfortunately our ANT expert is out of office for the Easter vacation. They'll get back to you on Tuesday April 19th. Happy Easter!

Hi Simon,

Thanks for the reply,

From this ant_evt_handler,

static void ant_evt_handler(ant_evt_t * p_ant_evt, void * p_context)
{
    ret_code_t err_code = NRF_SUCCESS;

    if (m_channel != p_ant_evt->channel)
    {
        return;
    }

    switch (m_channel_type)
    {
        case CHANNEL_TYPE_SLAVE:
            /* fall through */
        case CHANNEL_TYPE_SLAVE_RX_ONLY:
            switch (p_ant_evt->event)
            {
                case EVENT_RX:
									  NRF_LOG_INFO("EVENT_RX...\r\n"); 
                    err_code = bsp_indication_set(BSP_INDICATE_CONNECTED);
								    
								    nrf_pwr_mgmt_feed(); //Function for indicating activity.
                    break;

                case EVENT_RX_FAIL:
									  NRF_LOG_INFO("EVENT_RX_FAIL...\r\n"); 
								    NRF_LOG_INFO("RIXTRONIX EVENT_RX_FAIL...\r\n"); 
                    err_code = bsp_indication_set(BSP_INDICATE_RCV_ERROR);
								
                    break;

                case EVENT_RX_FAIL_GO_TO_SEARCH:
									  NRF_LOG_INFO("EVENT_RX_FAIL_GO_TO_SEARCH...\r\n");
								    NRF_LOG_INFO("RIXTRONIX EVENT_RX_FAIL_GO_TO_SEARCH...\r\n"); 
                    err_code = bsp_indication_set(BSP_INDICATE_SCANNING);
                    break;

                case EVENT_CHANNEL_CLOSED:
									  NRF_LOG_INFO("EVENT_CHANNEL_CLOSED...\r\n");
								    NRF_LOG_INFO("BSP_INDICATE_SCANNING...\r\n");//31Mar22 Rixtronix LAB
                    //nrf_pwr_mgmt_shutdown(NRF_PWR_MGMT_SHUTDOWN_GOTO_SYSOFF); //default
								     err_code = bsp_indication_set(BSP_INDICATE_SCANNING);
									  //nrf_pwr_mgmt_shutdown(NRF_PWR_MGMT_SHUTDOWN_CONTINUE);
								    nrf_pwr_mgmt_feed(); //Function for indicating activity.
								    
								
                    break;

                case EVENT_RX_SEARCH_TIMEOUT:
									 //Rixtronix LAB
								   //8 Sept 2021, 
								   //on search timeout, and idle, make device on if there is a signal from sensor ?
									  NRF_LOG_INFO("EVENT_RX_SEARCH_TIMEOUT...\r\n");
                    //err_code = bsp_indication_set(BSP_INDICATE_IDLE);//default
								    err_code = bsp_indication_set(BSP_INDICATE_SCANNING);
								    nrf_pwr_mgmt_feed(); //Function for indicating activity. default
								     
                    break;
            }
            break;
    }
    APP_ERROR_CHECK(err_code);
}

on EVENT_CHANNEL_CLOSED:

How can I rescan again ?
