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").

"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"

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.

I asked you before if you meant switching between BLE and some other protocol and you said, "NO".

Now you're saying that you do want to switching between BLE and some other protocol ?

what is the meaning of "makes no sense - BLE is 2.4GHz"? I mean the function of BLE and 2.4GHz can used to work together. The example of "/proprietary_rf/esb_ptx" in SDK12.1 can used in the example of "ble_uart_app".

that makes no sense - BLE is 2.4GHz.

No, the nRF5 always work at BLE，then i want to switch the 2.4G any time。I mean switching between BLE and 2.4G.

The nRF5 always work at 2.4GHz - do you mean switching between BLE and some other protocol (both at 2.4GHz) ?
