Not getting NRF_EVT_FLASH_OPERATION_SUCCESS

[Lodge]

Hi all, After receiving data from my host app, I am trying to write to write the data to flash with the sd_flash_write command. I have 3 pages of data to write, so need to make sure the last write has finished by waiting for NRF_EVT_FLASH_OPERATION_SUCCESS. I do not receive this however while the ble is running. I placed the sd_evt_get in the interrupt handler:

void SWI2_IRQHandler(void)
{
	uint error;
	uint event;
	word length;
	bool softEvent = true;
	bool bleEvent = true;
	
	while (1)
	{
		if (softEvent)
		{
			error = sd_evt_get(&event);
			if (error == NRF_ERROR_NOT_FOUND)
				softEvent = false;
			else if (error != NRF_SUCCESS)
			{
				// Error
			}
			else
			{
				BluetoothSystemEventHandler(event); // Doesn't get called	

			}
		}
		if (bleEvent)
		{
			length = bleBufferSize;
			error = sd_ble_evt_get(bleEventBufferOffset, &length);
			if (error == NRF_ERROR_NOT_FOUND)
				bleEvent = false;
			else if (error != NRF_SUCCESS)
			{
				// Error
			}
			else
				BluetoothEventHandler((ble_evt_t *) bleEventBufferOffset);
		}
		if (!softEvent && !bleEvent)
			break;
	}
}

And in my main() I have just:

while(1)
{
	__wfi();
}

However, the BluetoothSystemEventHandler() never gets called. Is this the correct way to do it? Thanks again.

It seems it is the while loop waiting for the state to change. This is what I have in the flash write function-

flashState = FLASH_STATE_IDLE;
	error = sd_flash_page_erase(((NRF_FICR->CODESIZE - 3) + page));
	if (error != NRF_SUCCESS)
		return false;
	
	while (flashState == FLASH_STATE_IDLE); // If I remove this I get the event
	if (flashState == FLASH_STATE_ERROR)
		return false;

If I remove the while loop, I do get the event. How can I change the while loop to wait for status change? Thanks.
