使用ESP32-C3的SoftAP模式创建web服务器中的问题
Posted: Tue Sep 05, 2023 1:41 am
我正在使用ESP32-C3的SoftAP模式创建web服务器，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，我发现手机可以连接上热点，但无法访问页面web页面。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，手机是华为p30，系统hormany os 2.0.0.268。
现象细节：
手机成功连接到ESP32-C3的热点后熄屏。
一段时间后，手机可以连接上热点，但无法访问页面web页面。
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代码和日志，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！
我的web server代码使用例程中的http_server->file_serving框架，相关代码如下：
以下是log：
