### 配置MQTT连接

Broker Address（MQTT代理服务地址）: **47.106.149.52** （DDA-IOT云平台v3.0服务地址）

Broker Port (MQTT代理服务端口)：**1883**

User Name(MQTT客户端，即网关与后台的MQTT服务器进行连接的令牌)：格式为网关的SN，也可通过"[**创建设备后复制访问令牌**](/she-bei-jie-ru/chuang-jian-she-bei.md#huo-qu-fang-wen-ling-pai)"进行获取。

### 连接成功

### 推送数据

我们可以开始简单用MQTT.fx工具模拟网关的MQTT协议向服务器发送一个终端遥测数据

**topic:**&#x20;

```
v1/gateway/telemetry
```

**payload:**

```
{
	"WG12345678": [{
		"ts": "1609144280398",
		"values": {
			"H": "60",
			"mode": "2",
			"NET4GSTA": "1,0",
			"mT": "3,0,2",
			"mFifo": "5528,5528,113,113",
			"DDA": "1",
			"boxSta": "0",
			"TH": "31.21,35.8",
			"NR": "42651,52212",
			"Lat": "-0.000000",
			"Lon": "-0.000000",
			"SDR": 1
		}
	}]
}
```

在上面的示例中我们"ts":"1609144280398"，是具有毫秒精度的[Unix时间戳](https://en.wikipedia.org/wiki/Unix_time)。例如：值’1609140420031’转换后是’2020-12-28 16:31:20’。

### 数据推送成功

以下为最终效果，通过模拟工具与后台进行连接并通过MQTT协议作数据推送
