硬件：硬石STM32F407  LAN8720
软件：        MDK5.2.5，evn0.7.0，rtt3.0.4
1、env配置
	未找到onenet选项，pkgs --upgrade 更新后选择onenet

2、按照教程[onenet配置](https://www.rt-thread.org/qa/forum.php?mod=viewthread&tid=7088&highlight=onenet)
3、编译后onenet_port_data_process未定义，自己定义一下，内容先空着
```int onenet_port_data_process(char *recv_data, rt_size_t size)
{
	rt_kprintf(" <br>%s <br>", recv_data);
	return 0;
}```
4、在msh下输输入
```msh />onenet_mqtt_init
D/ONENET] (mqtt_connect_callback:45) Enter mqtt_connect_callback!
[MQTT] ipv4 address port: 6002
[MQTT] HOST = '183.230.40.39'
[I/ONENET] OneNET MQTT initialize success.
msh />[MQTT] MQTT server connect success
[MQTT] Subscribe #0 /test_topic OK!```
5、在onenet上查看设备已经在线

6、在msh下输入
```onenet_upload_cycle
msh />[D/ONENET] (onenet_upload_data:111) buffer : {"temperature":83}
[E/ONENET] (onenet_upload_data:117) OneNet Send data failed! Handle response(0) error!
[MQTT] net_read 0:1, break!
[D/ONENET] (mqtt_offline_callback:55) Enter mqtt_offline_callback!
```
![微信截图_20180604211423.png](/uploads/201806/04/211510vysin3xzhysyhkyy.png)
定位到错误位置
```    if (webclient_handle_response(session))
    {
        if (session->response != 200)
        {
            log_e("OneNet Send data failed! Handle response(%d) error!", session->response);
            result = -RT_ERROR;
            goto __exit;
        }
    }```
单步调试session->response = 0
问题先放一下，感觉是webclient相关的问题
7、测试MQTT协议下发命令
在onenet的设备管理 使用下发命令，终端上可以接收到

修改

```
#define WEBCLIENT_HEADER_BUFSZ      1024
#define WEBCLIENT_RESPONSE_BUFSZ    1024
#define WEBCLIENT_TLS_READ_BUFFER   4096
```

还是一样的错误，调试了下感觉是socket recv有问题
webclient_handle_response->rc = webclient_read_line(session, mimeBuffer, WEBCLIENT_RESPONSE_BUFSZ);-> rc = webclient_recv(session, (unsigned char *)ptr, 1, 0);->recv(session->socket, buffer, len, flag);->lwip_recv(sock, mem, len, flags);->lwip_recvfrom(s, mem, len, flags, NULL, NULL);

测试了下lwip2.02是ok的
