RE: Check NUS paket is sent ( Data > 23 bytes ) and redy for new transmission

you need to wait for the BLE_EVT_TX_COMPLETE event, in addition hold a variable which has the buffer length.

then every time you send a package, you substract to know the offset to sent the next bytes from and increment the offset.
and do it all over until the connection breaks or the buffer is empty.

        case BLE_EVT_TX_COMPLETE:
        	if(m_DataOffset < m_DataSize){ // have we reached the end of buffer
        		m_ble_nus_c.conn_handle = p_ble_evt->evt.common_evt.conn_handle; // Multi connection handling
        		SendNUSData(&m_ble_nus_c); // here the data is sent
        	}
        	break;

Hope this helps
