EVENT_CHANNEL_CLOSED ?

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!

Best regards,

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 ?

Best regards,

I believe this should work yes, though you should only open the channel that for instanced closed or timeout.

Hi Kenneth,

Thanks for the reply

How do we know which channel is closed ? I have HRM and BSC and BPWR ?

I want to log it to SDcard on different state, but always crashed, any ideas ?

Regards,

Rixtronix

Typically by p_ant_evt->channel

Hi Kenneth,

Thanks for the reply, when I make :

 case EVENT_CHANNEL_CLOSED:
									  NRF_LOG_INFO("EVENT_CHANNEL_CLOSED...\r\n");
								    NRF_LOG_INFO("BSP_INDICATE_SCANNING...\r\n");//31Mar22 Rixtronix LAB
            					     err_code = bsp_indication_set(BSP_INDICATE_SCANNING);
								    nrf_pwr_mgmt_feed(); //Function for indicating activity.
								   /************REOPEN all channels Rixtronix LAB 4May2022*************/
								   
								     err_code=sd_ant_channel_open(HRM_CHANNEL_NUM);
								       nrf_delay_ms(888);	
								     err_code=sd_ant_channel_open(BSC_CHANNEL_NUM);

it keeps restarting,

but if I do :

 case EVENT_CHANNEL_CLOSED:
									  NRF_LOG_INFO("EVENT_CHANNEL_CLOSED...\r\n");
								    NRF_LOG_INFO("BSP_INDICATE_SCANNING...\r\n");//31Mar22 Rixtronix LAB
                
								     err_code = bsp_indication_set(BSP_INDICATE_SCANNING);
				
								    nrf_pwr_mgmt_feed(); //Function for indicating activity.
								   /************REOPEN all channels Rixtronix LAB 4May2022*************/
								   
								     err_code=sd_ant_channel_open(HRM_CHANNEL_NUM);
								       

It's stable,

Any clues on solving it ?

Rixtronix

Hi Kenneth, any clues ?

"Restarting"/"crashing" etc simply means that an api call have returned an error code, and that the code jumped to the fault handler, by default the fault handler is setup to execute a system reset, my suggestion is to build with DEBUG and look at the fault handler to find the file name, line number and error code that caused the assert.

Kenneth

Hi Kenneth,

Thanks for the reply,

I can't get error code that caused the assert,

Code and output :

when I commented out : 

 //err_code=sd_ant_channel_open(BSC_CHANNEL_NUM);
                                     //APP_ERROR_CHECK(err_code);

It's running and scanning for HRM, but will not work if I open BSC and BPW,

Could you help us ?

Kind regards,

Rixtronix

In your project, there should be a file called app_error_weak.c (and likely also app_error_handler_keil.c since you are using Keil IDE), app_error_weak.c contain a fault handler: app_error_fault_handler()

This fault hault handler is called when an api return an error code, if you have added DEBUG to your preprocessor (as I can see you have) then this file should provide information about file name, line number and error code.

Hi Kenneth,

Thanks for the reply,

I saw :

SVCALL(SVC_ANT_CHANNEL_SEARCH_TIMEOUT_SET, uint32_t, sd_ant_channel_search_timeout_set (uint8_t ucChannel, uint8_t ucTimeout));

at

nRF5_SDK_17.0.2_d674dde\components\softdevice\SoftDevice\headers\include\ant_interface.h LINE 457

can I change

uint8_t ucTimeout; to

int32_t Timeout

and Timeout =10000 ?

Regards,

Rixtronix

Looking at the description in ant_interface.h

/** @brief This function sets the channel search timeout. For a slave channel, the configuration applies to rx search
 *         timeout. For a master channel, the configuration applies to timeout for starting a transmitter using group transmitter
 *         initiation requirements.
 *
 * @param[in] ucChannel is an unsigned char (1 octet) denoting the channel number to set.
 * @param[in] ucTimeout is an unsigned char (1 octet) denoting the timeout value.
              When applied to an assigned slave channel, ucTimeout is in 2.5 second increments. Default = 10 (25s) at channel assignment
              When applied to an assigned master channel, ucTimeout is in 250ms increments. Default = 0 (disabled) at channel assignment
 *
 * @return  ::NRF_SUCCESS
 *          ::NRF_ANT_ERROR_INVALID_PARAMETER_PROVIDED
 */
#define sd_ant_channel_rx_search_timeout_set(ucChannel, ucTimeout)      sd_ant_channel_search_timeout_set(ucChannel, ucTimeout)
SVCALL(SVC_ANT_CHANNEL_SEARCH_TIMEOUT_SET, uint32_t, sd_ant_channel_search_timeout_set (uint8_t ucChannel, uint8_t ucTimeout));
