碰到wifi: ap_probe_send over, resett wifi status to disassoc问题

[Jimmy1688]

IDF版本为3.2.2。碰到的问题描述
不停在连接WIFI和从WIFI上断开，这个问题是偶发的，同一热点下有两个设备，一个正常，另一个出现这样的问题。
我尝试关闭路由器后，重新打开，现象依旧。
重启设备后，恢复正常。
不知道如何办。
下面是我摘取的一段log

wifi: ap_probe_send over, resett wifi status to disassoc
这句打印出现，是在 beacon timeout 时，发送 probe request 后没有找到自己连接的 AP 。
这时会发送 disassoc ，然后断开连接。

如果 AP 不存在了，比如掉电之类，出现这种 log 就是正常现象。

如果 AP 正常，出现 beacon timeout，就需要详细分析下。

你使用的 AP 是什么型号？

测试过程中 除了 连接 WiFi ，断开 WiFi ，还有其他什么操作吗？

出问题的 板子的剩余内存还有多少？

可以提供下你的 代码让我来 debug这个问题吗？

Hi,

如果连同一个 AP，有一个有问题，另一个没有问题，而且重起 AP 无法恢复，可能是 WiFi RX 挂了，导致收不到 beacon。这个问题应该在 v3.2 中 IDF commit: 3750fe94 中 fix 掉了。

目前看，可能是内存泄漏，引起这个问题。

Hi Jimmy,

你提到的内存泄漏是指应用层还是 IDF 存在内存泄漏？为什么怀疑是内存泄漏导致？
