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

[2020-12-29 13:32:43.668 (UTC+0100)] warn/userland      AcceptAll Certificate Verification. Any remote certificate will be accepted.
[2020-12-29 13:32:43.671 (UTC+0100)] warn/network       Connection to opc.tcp://localhost:4840 failed with error: Connection refused
[2020-12-29 13:32:43.671 (UTC+0100)] info/client        Client Status: ChannelState: Closed, SessionState: Closed, ConnectStatus: BadDisconnect

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

通过将以太网电缆插入两个覆盆子并出于某种原因通过无线连接到服务器，设法获得基本的客户端/服务器通信。

认为我其中一个存在一些设置问题。
