Is there any possible way to sedn the data from peripheral device(nrf52832 dev kit) to nrf52840 dongle which is connected to Bluetooth-less desktop

Question

Hello, 
 In my project, i want to send the data from the ble device nrf52832 dev kit to the nrf52840 dongle which is connected to a Bluetooth-less desktop. Some desktop doesn't have inbuilt Bluetooth and for that, i used an nrf52840 dongle with the help of nrf connect desktop app i flashed the dongle(here i don't have any example or source file, firmware flashed directly by the app), and when I connect it to desktop & scan the peripheral devices with Bluetooth low energy option in nrf connect app. even I can connect the peripheral devices. 
 Now the issue is how can I send the data from the nrf52832 dev kit to nrf dongle because there is no source file I couldn't add code to receive the data. i tried ble_app_blinky and ble_app_blinky_c examples to send the button state data from peripheral to central so can i use the same for nrf52832 and dongle.?? 
 if so, using the dongle can we connect it to PC and send the data to pc.?? 
 please let me know how can i implement this. 
 Thank You.

Hello, 
 i can able to send the data continuously by doing like this, 
 int main(void)
{
 ret_code_t ret;
 static const app_usbd_config_t usbd_config = {
 .ev_state_proc = usbd_user_ev_handler,
 };

 //ret = NRF_LOG_INIT(NULL);
 //APP_ERROR_CHECK(ret);

 ret = nrf_drv_clock_init();
 APP_ERROR_CHECK(ret);

 //nrf_drv_clock_lfclk_request(NULL);
 //while(!nrf_drv_clock_lfclk_is_running())
 //{
 // /* Just waiting */
 //}

 //ret = app_timer_init();
 //APP_ERROR_CHECK(ret);

 //ret = app_timer_create(&m_mouse_move_timer, APP_TIMER_MODE_REPEATED, mouse_move_timer_handler);
 //APP_ERROR_CHECK(ret);

 //init_bsp();

//#if NRF_CLI_ENABLED
// init_cli();
//#endif

 ret = app_usbd_init(&usbd_config);
 APP_ERROR_CHECK(ret);

// app_usbd_class_inst_t const * class_inst_mouse;
//#if CONFIG_HAS_MOUSE
// class_inst_mouse = app_usbd_hid_mouse_class_inst_get(&m_app_hid_mouse);
//#else
// class_inst_mouse = app_usbd_dummy_class_inst_get(&m_app_mouse_dummy);
//#endif
// ret = app_usbd_class_append(class_inst_mouse);
// APP_ERROR_CHECK(ret);

 app_usbd_class_inst_t const * class_inst_kbd;
#if CONFIG_HAS_KBD
 class_inst_kbd = app_usbd_hid_kbd_class_inst_get(&m_app_hid_kbd);
#else
 class_inst_kbd = app_usbd_dummy_class_inst_get(&m_app_kbd_dummy);
#endif
 ret = app_usbd_class_append(class_inst_kbd);
 APP_ERROR_CHECK(ret);

 NRF_LOG_INFO("USBD HID composite example started.");
 
 if (USBD_POWER_DETECTION)
 {
 ret = app_usbd_power_events_enable();
 APP_ERROR_CHECK(ret);
 }
 else
 {
 NRF_LOG_INFO("No USB power detection enabled
Starting USB now");

 app_usbd_enable();
 app_usbd_start();
 }

 while (true)
 {
 counter+=1;

 nrf_delay_ms(50);

 app_usbd_hid_kbd_key_control(&m_app_hid_kbd, counter, 1); // Press the key

 nrf_delay_ms(50);

 app_usbd_hid_kbd_key_control(&m_app_hid_kbd, counter, 0); // Release the key

 nrf_delay_ms(50);

 if(counter==39)
 {
 counter=3;
 }

 while (app_usbd_event_queue_process())
 {
 /* Nothing to do */
 }
//#if NRF_CLI_ENABLED
// nrf_cli_process(&m_cli_uart);
//#endif

 //UNUSED_RETURN_VALUE(NRF_LOG_PROCESS());
 /* Sleep CPU only if there was no interrupt since last loop processing */
 __WFE();
 }
}
 
 afte this i started to add the code for ble_app_uart_c but after adding this the first time I got 
 nrf_drv_clock_init() return ERROR 133 [NRF_ERROR_MODULE_ALREADY_INITIALIZED] 
 then I commented out nrf_drv_clock_init() because maybe in a soft device its initialized and i checked that with 
 ret = nrf_drv_clock_init_check(); NRF_LOG_INFO("ret:%d
",ret); 
 it returns 1 so it is initialized then after commenting out no errors but I couldn't send the data to Notepad. 
 what will be the problem.? 
 Thank You
