我在IBM Bluemix IoTF中创建了一个设备，生成了身份验证令牌并且设置了所有内容。我正在尝试使用Python（ibm-iotf库）连接并向此设备发送消息，并且已创建该程序。但是当我运行程序时，我收到以下错误。请帮忙。

2016-03-21 11:04:15,786 ibmiotf.device.Client WARNING Unable to encrypt messages because TLSv1.2 is unavailable (MQTT over SSL requires at least Python v2.7.9 or 3.4 and openssl v1.0.1)

Answer 1

根据documentation：物联网平台需要TLS v1.2。我们建议使用以下密码套件：ECDHE-RSA-AES256-GCM-SHA384，AES256-GCM-SHA384，ECDHE-RSA-AES128-GCM-SHA256或AES128-GCM-SHA256。

确保您拥有Python版本和Open SSL 1.0.1，它支持TLS v1.2
