器件型号：CC3200 Thread 中讨论的其他部件：、 CC3100
尊敬的团队：
下面是 我使用的设置详细信息：
- CC3200 Wi-Fi 芯片。
- SDK： CC3200SDK_1.3.0
- 服务包：CC3100_CC3200_ServicePack_1.0.1.15-2.14.0.0
目标：收集 能量计 数据并通过企业网络将其发布在 MQTT 服务器上。
- RS485协议
- WPA 企业 安全
参考示例代码：
- 我正在使用 MQTT 客户端代码、并根据要求进行了更改
- 已参考企业连接的 ent_WLAN 示例代码
问题：无法连接到网络
- 尝试在不使用证书的情况下连接到网络
- 根据该帖子，已将 pValues 保持为“零”，以便在 sl_WlanSet()函数中禁用服务器身份验证
- 我仍然无法连接到网络。
- 已尝试使用以下两种功能设置
- SL_WlanSet (SL_WLAN_CFG_General_Param_ID、SL_WLAN_General_Param_disable_ENT_SERVER_AUTH、1、&pValues)； (参考：TI 帖子)
- SL_WlanSet (SL_WLAN_CFG_General_Param_ID、19、1、&pValues)；(参考：Ent_WLAN 示例代码)
- 结果仍然是负面的
- 我正在尝试 ping 内部服务器、以确保我们已连接到网络
- 将主机名从"www.ti.com "替换为"vt1.vitesco.com "
这是否会导致任何问题？
- 将主机名从"www.ti.com "替换为"vt1.vitesco.com "
如需参考、请查找以下日志
这可能是什么问题？希望您能尽快与上述问题取得联系。
以下是我使用的 MQTT 客户端代码的代码片段、 我请求您 提供正确的解决方案？
