5 AT-DEVICE接收应答无效

RAW看到已经回了0, CONNECT OK... 
为什么还是sim0 device socket(0) wait connect result timeout
怎么设置接收事件

已经注册
```
static int sim800c_device_register(void)
{
    return at_device_register(&(sim800c->device),
                              sim800c->device_name,
                              sim800c->client_name,
                              AT_DEVICE_CLASS_SIM800C,
                              (void *) sim800c);
}
INIT_APP_EXPORT(sim800c_device_register);
```

```
if(sim800c->device.sockets->ops->at_connect(sim800c->device.sockets, "47.96.147.99", 18085,AT_SOCKET_TCP,1)==RT_EOK)
{
    rt_kprintf("Socket create ok.\n");
}
else{
    rt_kprintf("Socket create failed.\n");
    return -RT_ERROR;
}
```
我看sim800c_socket_connect里面是由SET_EVENT的
```
static int sim800c_socket_connect(...)
{
....
__retry:
    /* clear socket connect event */
    event = SET_EVENT(device_socket, SIM800C_EVENT_CONN_OK | SIM800C_EVENT_CONN_FAIL);
    sim800c_socket_event_recv(device, event, 0, RT_EVENT_FLAG_OR);
}
```
