nrf52:SPI master with softDevice can not work

[wpb3dm]

Hi, nrf52832, softdevice:S132 My SPI master program can initialize the SD Card succefully. But, when I put it into the examples of ble_app_uart on nRF5_SDK_11.0.0_89a8197, it can not work. It write a data through SPI, but can not receive any ack. Its spi_event_handler not been called. Why? The following is some code of the main function:

int main(void)
{
    uint32_t err_code;
    bool erase_bonds;
	
    APP_TIMER_INIT(APP_TIMER_PRESCALER, APP_TIMER_OP_QUEUE_SIZE, false);
    uart_init();
    buttons_leds_init(&erase_bonds);
	   
    ble_stack_init();	
    gap_params_init();	 
    services_init();	
    advertising_init(); 
    conn_params_init();	

    printf("\r\nUART Start!\r\n");
    err_code = ble_advertising_start(BLE_ADV_MODE_FAST);
    APP_ERROR_CHECK(err_code);
   SDHost_Test();

for();
}
........

void spi_event_handler(nrf_drv_spi_evt_t const * p_event)
{
    spi_xfer_done = true;
}

u8 SPI1_WriteOneByte(u8 TxData)
{
    uint8_t spi_txbuf = TxData;

	
	spi_xfer_done = false;		
    nrf_drv_spi_transfer(&m_spi_master, &spi_txbuf, 1, NULL, 0);
	while (!spi_xfer_done)
	{
	   __WFE();
	}

	return true;

}

OK，I have find the problems. With the softDevice, the SPI frequency can only be set once.

Hello, what's the meaning of "With the softDevice, the SPI frequency can only be set once."? I notice you just set the SPI frequence once in your code.
