2.4G communication

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

[Martinchen]

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.

switching between BLE and 2.4G

that makes no sense - BLE is 2.4GHz.

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".

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 ?

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_pin_write(LED_BLE, 0); //³õʼ״̬µçƽÀ­µÍʹ֮²»ÁÁ

			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();

			{

				{
