[参考译文] LAUNCHCC3235MOD：。 NET 连接到 tcpechotls 问题

https://e2e.ti.com/support/wireless-connectivity/wi-fi-group/wifi/f/wi-fi-forum/1277337/launchcc3235mod-net-connect-to-tcpechotls-question

在使用 python 脚本运行(请参阅 https://e2e.ti.com/support/wireless-connectivity/wi-fi-group/wifi/f/wi-fi-forum/1276970/launchcc3235mod-getting-tcpechotls-to-work-with-python-script-from-windows/)之后、我试图使 tcpechotls 与 Windows .Net framework 4.8.1配合使用、并在" Console "中继续获取"RemoteCertificateNameMismatch "。 WriteLine ("证书错误：｛0｝"、sslPolicyErrors)；"。 我修改了 tcpechotls 中的一些内容、使其在工作站模式下以主机名运行并更改了端口、但这些移动对 python 脚本"python tcpSendReceiveTLS.py 192.168.1.99 58800 1 certs/cacert.pem -s100"(C：\ti_simplelink_cc32xx_sdk_7_10_00_13\tools\cc32xx_tools")起作用。 原始但更改了 Microsoft 示例中的连接代码，位于 SslStream Class (System.Net.Security)| Microsoft Learn
