how can nrf51822  make 2.4G communication and BLE communication arbitrary switch?

Sligthly old blog post, but in principle should still be valid:

I got idea for switching between BLE and 2.4GHZ.But when i was disabled to softdevice using "sd_softdevice_disable()",the program come in "while (loop);". If i want to  close the softdevice, what am i going to do?  My  idea is this code for  switching between BLE and 2.4GHz.

	nrf_gpio_cfg_output(LED_BLE);		//ble±êÖ¾
			nrf_gpio_pin_write(LED_BLE, 0); //³õʼ״̬µçƽÀ­µÍʹ֮²»ÁÁ
			
			nrf_gpio_cfg_output(LED_TXS);		//2.4G±êÖ¾
			nrf_gpio_pin_write(LED_TXS, 0); //³õʼ״̬µçƽÀ­µÍʹ֮²»ÁÁ
			
			nrf_gpio_cfg_input(switch_24toble,NRF_GPIO_PIN_NOPULL);
			
			ble_stack_init();
			ble_app_cfg_start();
			
    // Enter main loop.
    for (;;)
    {
			
			pinvalue = nrf_gpio_pin_read(switch_24toble);
			if (pinvalue == 1)
			{
				running_mode = BLE;
			}
			else
			{
				running_mode = GHZ;
			}
			
			 power_manage();
			
			if (running_mode != previous_mode)
			{
				previous_mode = running_mode;
				if (running_mode == BLE)
				{
						AppTx_stop(); //Í£Ö¹·¢ËÍ£¬¿ªÊ¼ble
						ble_stack_init();
						ble_app_cfg_start();
				}
				else if (running_mode == GHZ)
				{
					//ble_app_cfg_stop();
					ble_stack_stop(); //Í£Ö¹ble£¬×¢Òâֹͣ˳Ðò£»¿ªÊ¼2.4GHZ
					
					
					esb_tx_init();		//³õʼ»¯·¢ËÍÅäÖÃ
					ret = AppTx_Send((uint8_t *)buf,5);			//·¢ËÍÒ»Ö¡¹Ì¶¨Ö¡£¬²âÊÔÓÃ
					if (ret < 0)
					{
						ret = 0;
					}
				}
				
void ble_stack_stop(void)
{
    uint32_t err_code;

    err_code = softdevice_handler_sd_disable();
    APP_ERROR_CHECK(err_code);
}

uint32_t softdevice_handler_sd_disable(void)
{
    uint32_t err_code = sd_softdevice_disable();
#if 1
    if (err_code == NRF_SUCCESS)
    {
        m_softdevice_enabled = false;
        nrf_drv_clock_on_sd_disable();
    }
#else
    m_softdevice_enabled = !(err_code == NRF_SUCCESS);
#endif
    return err_code;
}

"2.4GHz" is just a frequency

BLE operates at 2.4GHz

So "switching between BLE and 2.4GHZ" means nothing.

You mean, "switching between BLE and a proprietary protocol"

yes，I know the example of "\examples\multiprotocol\ble_app_gzll",but i have some troubles when i transplant to my project of "ble_uart_app".

 // Enter main loop.
    for (;;)
    {
			power_manage();
			//pinvalue = nrf_gpio_pin_read(switch_24toble);   //pinvalue = 0
			if (pinvalue == 1)     
			{
				running_mode = BLE;
			}
			else
			{
				running_mode = GHZ;
			}
			
			if (running_mode != previous_mode)
			{
				previous_mode = running_mode;
				if (running_mode == BLE)
				{
						AppTx_stop(); 
						ble_stack_init();
						ble_app_cfg_start();
				}
				else if (running_mode == GHZ)
				{
					//ble_app_cfg_stop();
					ble_stack_stop(); 
					
					esb_tx_init();		
					ret = AppTx_Send((uint8_t *)buf,5);			
					if (ret < 0)
					{
						ret = 0;
					}
					
					if (TxRxPacket.TxFlage == 1) 
					{
							TxRxPacket.TxFlage = 0;  
						 // Toggle one of the LEDs.
							nrf_gpio_pin_write(LED_TXS, 1);
							nrf_delay_us(100000);
							nrf_gpio_pin_write(LED_TXS, 0);
							nrf_delay_us(100000);
					}
				}
			}
			

first,the code dehind of "power_manage()" is not running when the "power_manage();"has executed. when i put him somewhere else the softdevice is not close(sd_softdevice_disable() running will lead to program go into "while (loop);" in the "app_error.c").
