ESP32-C3 SoftAP模式下的连接问题

[renbingcheng]

问题描述：
我正在使用ESP32-C3的SoftAP模式创建Wi-Fi热点，并使用手机连接到该热点。当手机连接成功并熄屏一段时间后，我发现手机无法获取热点的信息。在此期间，ESP32-C3不输出任何日志，并且无法响应。问题只能通过重新启动ESP32-C3来解决。我使用的ESP-IDF版本是v4.4.3。

现象细节：

手机成功连接到ESP32-C3的热点后熄屏。
一段时间后，手机无法获取热点信息。
ESP32-C3在此期间没有任何日志输出，表现为无响应。
问题只能通过重新启动ESP32-C3解决，重连热点无效。

我已附上了部分相关的日志，并正在寻求任何可能的解决方案或建议。有没有人遇到过类似的问题？非常感谢大家的支持和帮助！

以下是重连热点时ESP32C3输出的log信息：

手机熄屏后断开与 AP 之间的连接，如果手机没有主动发送解除关联的报文，则设备端 ESP32-C3 作为 softap 不会有其他打印，只有等到默认 300s 之后才会解除当前 STA 的认证，由于之前关联认证的信息在 softap 端没有被清除，在此期间(300s 以内)手机可能连不上 softap，可以通过 esp_wifi_set_inactive_time 配置超时时间；
手机如果主动发送解除关联的报文，则设备端 ESP32-C3 作为 softap 会打印：
