Ibm cloud Arduino未使用MQTT连接到Watson IoT

我正在尝试将arduino连接到Watson IoT。 使用以下命令：

mqtt.connect(0, "d6acq3.messaging.internetofthings.ibmcloud.com",1883,"d:d6acq3:Arduino_Helligkeit:1234567890","use-token-auth","<as it was provided>");

在Watson平台上，我在设备的连接日志中看到以下消息：

Closed connection from 93.231.145.115. 
The topic is not valid: use-token-auth 
The topic does not match an allowed rule    07.02.2017 11:58:16

提前感谢您提供的帮助。正如Dan所说，Watson IoT平台只允许使用特定的主题字符串，因此您应该确认您使用的主题字符串是正确的

对于应用程序，事件主题： iot-2/type/{device type}/id/{device id}/evt/{event type}/fmt/{format type}

对于应用程序，命令主题： iot-2/type/{device type}/id/{device id}/cmd/{command type}/fmt/{format type}

对于设备，事件主题： iot-2/evt/{事件类型}/fmt/{格式类型}

对于设备，命令主题： iot-2/cmd/{命令类型}/fmt/{格式类型}

但是，我在日志中看到的情况表明，您正在尝试使用比您在文章中指定的更长的客户端ID进行连接。我看到这个错误：

令牌身份验证失败（设备不存在）：ClientID='d:d6acq3:Arduino_Helligkeit:1234567801486464057428'

因此，您需要检查以确保您的连接使用的是您已注册的正确设备ID

亲爱的瓦莱丽，据我所知，我甚至连电话都没有。所以，我认为这个话题还没有发挥作用，对吧？同时，我创建了另一个设备ID（18fe34a46709），但我也无法连接。我尝试将第三个设备ID与MQTTBox（Chrome客户端）连接起来，这可以正常工作。（至少对于连接而言）我看到您的MQTTBox连接工作正常。检查设备18fe34a46709时，它收到此错误，因此看起来它在主题字段中输入了错误的值：主题无效：使用令牌身份验证主题与允许的规则不匹配。Reason=“主题无效：使用令牌身份验证主题与允许的规则不匹配”
