Close ANT HRM channel and save to SDcard ?

After issuing the sd_ant_channel_close() you need to wait for the event that indicate the channel is closed (this may take some time, since it depends for instance on the channel period).

Kenneth

the event that indicate the channel is closed ,which event ? thanks...

code :

 
		err_code = sd_ant_channel_close(HRM_CHANNEL_NUM);
     APP_ERROR_CHECK(err_code);
		
		 if (err_code==NRF_SUCCESS )
			 {
				 
		      err_code = sd_ant_channel_unassign(HRM_CHANNEL_NUM); 
				 NRF_LOG_INFO("WRITE HRM TO SDcard Page 0...\r\n");
		
				 
			 }

Please correct me the sequence and where should I put that sequence of closing the channel, write to SDcard and reopen again ?

Thanks

You should receive an EVENT_CHANNEL_CLOSED event in your event handler. The easiest way to find the name of the event handler may be to search the project for NRF_SDH_ANT_OBSERVER(). It may look something like this (example taken from ant_hrm_tx):

You may also add your own NRF_SDH_ANT_OBSERVER() if you like.

Hi Kenneth,

I've found that function at ant_state_indicator.c

on this case :

  case EVENT_CHANNEL_CLOSED:
                    NRF_LOG_INFO("EVENT_CHANNEL_CLOSED...\r\n");
                    nrf_pwr_mgmt_shutdown(NRF_PWR_MGMT_SHUTDOWN_GOTO_SYSOFF); //default

I never that get "case",

and I have put at E:\nRF5_SDK_17.0.2_d674dde\components\ant\ant_profiles\ant_hrm\pages\ant_hrm_page_0.c

function :

static void page0_data_log(ant_hrm_page0_data_t const * p_page_data)

err_code = sd_ant_channel_close(HRM_CHANNEL_NUM);

The interrupt from HRM keeps coming and system reset

How can I close it and reopen ?

Thanks

You write system reset, the only way the chip will reset is if power is removed, pin reset is pressed or NVIC_SystemReset() is called. I believe the case here is that NVIC_SystemReset() is called, and likely from the app_error_fault_handler(), you should build with DEBUG to find the exact cause.

Kenneth

Ok, I will try build and use DEBUG, anyway,

I never got these breakpoints  :

When it's connected on ANT HRM, it keeps running never stop on that breakpoint ?

Any ideas ?

Thanks

Hi Kenneth,

When I put DEBUG,

I got this :

                                                                             

nfo> app: Err_code libuarte_init libuarte1 0
                                 

rror> app: SOFTDEVICE: ASSERTION FAILED

What's the cause of "SOFTDEVICE: ASSERTION FAILED" ?

How can we trace it ?

Thanks
