HarmonyOS 鸿蒙Next wifi连接报错2501000？

出现错误码‘2501000’的原因之一是当前样机已连接热点，请在执行connectToCandidateConfig方法前确保样机未连接到wifi即可（可删除网络后再次尝试运行上述代码）。

//参考demo如下：
import { wifiManager } from '@kit.ConnectivityKit';
import { promptAction } from '@kit.ArkUI';
@Entry
@Component
struct Index {
@State message: string = ‘Hello World’;
async getLinkInfo() {
const linkInfo = await wifiManager.getLinkedInfo()
console.log(获取到的linkInfo信息为：${<span class="hljs-built_in">JSON</span>.stringify(linkInfo)})
<span class="hljs-keyword">if</span> (!wifiManager.isConnected()) {
  <span class="hljs-keyword">try</span> {
    <span class="hljs-keyword">let</span> config: wifiManager.WifiDeviceConfig = {

      preSharedKey: <span class="hljs-string">'wifi密钥'</span>,
      securityType: <span class="hljs-number">3</span>
    }
    wifiManager.addCandidateConfig(config).then(result =&gt; {
      console.log(<span class="hljs-string">'addCandidateConfig:'</span> + result)
      wifiManager.connectToCandidateConfig(result);
    }).catch((err: number) =&gt; {
      promptAction.showToast({ message: <span class="hljs-built_in">JSON</span>.stringify(err) })

    });
  } <span class="hljs-keyword">catch</span> (error) {
    promptAction.showToast({ message: <span class="hljs-built_in">JSON</span>.stringify(error) })

  }
} <span class="hljs-keyword">else</span> {
  promptAction.showToast({ message: <span class="hljs-string">'请断开wifi后再试'</span> })
}
}
