EVENT_CHANNEL_CLOSED ?

user91908

Dear Members,

How can I scan continously if I loss the sensor,

I have made at this function :

static void ant_evt_handler(ant_evt_t * p_ant_evt, void * p_context)

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.
								    
								
                    break;

but it's not scanning when it loss the sensor ,

Any clues ?

Kind regards,

Rixtronix

    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));

    ucTimeout is an unsigned char (1 octet) denoting the timeout value, the increment is mentioned in the description depending on slave or master channel.

    Best regards,

    Hi Kenneth,

    Thanks for the reply,

    Is it possible that I reload the timeout with timer,

    For example I set timer every 60s, and call  

    sd_ant_channel_rx_search_timeout_set(ucChannel, ucTimeout)

    So I can get long timeout ?

    Kind regards,

    Rixtronix
