我在将 Raspberry Pi 上的客户端连接到 Raspberry pi 上的服务器时遇到了一点问题，希望你们对如何解决它有一些想法。
它们都已使用本指南 https://open62541.org/doc/current/building.html进行设置
为简单起见，我也使用了他们网站上的简单客户端和服务器设置，位于
https://open62541.org/doc/current/tutorial_client_firststeps.html
和
https://open62541.org/doc/current/tutorial_server_firststeps.html
唯一的区别是因为我使用的是 UA_ENABLE_AMALGAMATION 选项
#include <open62541/plugin/log_stdout.h>
#include <open62541/server.h>
#include <open62541/server_config_default.h>
已更改为
#include "open62541.h"
我得到的读数是

对于服务器和

为客户
我可以用 UaExpert 连接到两个树莓派，但由于某种原因，客户端不想连接？
任何想法可能导致此问题？
这些也是 Open62541 的当前配置
