Hello, I'm facing the same issue, how did you solve it? (If you solved it...)

Sure, the problem is that I rewrote it without the softdevice_handler to have more control on soc events, as soon I'll finish it i'll get back to you. Thanks!

in that case, can I get your project (maybe send the link in the pvt message) so that i can see and investigate more why this is happening.

Yes, the sd_flash_page_erase goes without problems but alway busy... really can't figure out.

This seems very unlikely. if the sd_flash_page_erase went through without any errors, then after sometime you should either get NRF_EVT_FLASH_OPERATION_SUCCESS or NRF_EVT_FLASH_OPERATION_ERROR. There are no exceptions for this-

Hi Aryan, sorry to hear that, hope you're doing well now. I can debug the sd_evt_get and it seems that none of the flash operation done/error event is passed here so the code hangs in the sd_flash_page_erase() and the mb_flash_busy never goes false.

Hi, Sorry for late reply, I was sick all week. Looking at your code, the only possibility that ant_boot_settings_event is not called is when sd_evt_get function returns with NRF_ERROR_NOT_FOUND- Were you sure that the API that enabled some functionality to expect events went succesfully?

Forget to say that the ant_boot_settings_event() is never called... Does it mean i need to discard the softdevice_handler and rewrite that part as its in the ota_tester app?

The problem seems that i'm using the softdevice_handler in the project:

#define SOFTDEVICE_EVT_IRQ        SD_EVT_IRQn
void SOFTDEVICE_EVT_IRQHandler(void)
{
	
		// Added by me
		uint32_t ulEvent;
		while (sd_evt_get(&ulEvent) != NRF_ERROR_NOT_FOUND) // read out SOC events
		 {
				 ant_boot_settings_event(ulEvent);
		 }
				 
		// The original
    if (m_evt_schedule_func != NULL)
    {
        uint32_t err_code = m_evt_schedule_func();
        APP_ERROR_CHECK(err_code);
    }
    else
    {	 
				intern_softdevice_events_execute();
    }
}

This is at the end of the softdevice_handler.c, all the events runs here

I'm using the default one in the softdevice_handler file. I'll post it later but you can check the ant broadcast rx example, its the same. Thanks

Hi Max,

How did you add the ant_boot_settings_event? Something like this needs to be done

void SD_EVT_IRQHandler(void)
{
   uint32_t ulEvent;

   while (sd_evt_get(&ulEvent) != NRF_ERROR_NOT_FOUND) // read out SOC events
   {
       ant_boot_settings_event(ulEvent);
   }
}
