how to send the data to ble_app_uart , i used this line 

  ret = ble_nus_data_send(&m_nus,"hwllo",25,m_conn_handle);
but i am not receiving any data in ble_app

There are both Central & Peripheral examples for the Nordic UART Service (NUS) in the SDK.

Start with those ...

Have you tested your peripheral code with Nordic's app ?

Ok one thing I see is:

uint32_t ble_nus_data_send(ble_nus_t * p_nus,
                           uint8_t   * p_data,
                           uint16_t  * p_length,
                           uint16_t    conn_handle)

So you need to pass address of the data to be exact.

But before that have you used the basic ble_app_uart example in its raw form?

No , i couldn't able to receive the data from usb dongle , and i am not receiving any data too in termite from app 

even i installed cdc driver too .

[ps_anu]

yes i used , but i am new to nrf52840 usb dongle kit , i am not at all receiving the data from usb dongle . i merged the twi+adc example too

Was the function working fine in the default example?
