Hi Liu,

Please create another case when you have different question.

Please give more information than just pasting the code snippet.

yes, the example worked. but there is another problem, because i want to have dfu function, so i add files in the project, and modify the define

#define IS_SRVC_CHANGED_CHARACT_PRESENT 0

#define IS_SRVC_CHANGED_CHARACT_PRESENT 1

it can also connect,but data can not transfer. debug, the write handle is wrong:

static void on_write(ble_nus_t * p_nus, ble_evt_t * p_ble_evt)

{ ble_gatts_evt_write_t * p_evt_write = &p_ble_evt->evt.gatts_evt.params.write;

if (
    **(p_evt_write->handle == p_nus->rx_handles.cccd_handle)**
    &&
    (p_evt_write->len == 2)
   )
{
    if (ble_srv_is_notification_enabled(p_evt_write->data))
    {
        p_nus->is_notification_enabled = true;
    }
    else
    {
        p_nus->is_notification_enabled = false;
    }
}
else if (
         **(p_evt_write->handle == p_nus->tx_handles.value_handle)**
         &&
         (p_nus->data_handler != NULL)
        )
{
    p_nus->data_handler(p_nus, p_evt_write->data, p_evt_write->len);
}
else
{
    // Do Nothing. This event is not relevant for this service.
}

}

Hi Liu,

You have to make sure you included the 128bit UUID of the UART service in the advertising packet. The UUID should be included in m_adv_uuids that you added to scanrsp.

You can try to test again with the ble_app_uart example with no modification. I don't know why you need to modify anything.
