使用ESP32-C3的SoftAP模式创建web服务器中的问题

Postby renbingcheng » 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:

Code: Select all

/* Send HTTP response with a run-time generated html consisting of
 * a list of all files and folders under the requested path.
 * In case of SPIFFS this returns empty list when path is any
 * string other than '/', since SPIFFS doesn't support directories */

    char entrypath[FILE_PATH_MAX];
    char entrysize[16];

    extern const unsigned char upload_script_end[]   asm("_binary_page_cn_html_end");        

    const unsigned char *chosen_script_start;
    const unsigned char *chosen_script_end;

    if (english_model) {
        chosen_script_start = upload_script_en_start;
        chosen_script_end = upload_script_en_end;
    } else {
        chosen_script_start = upload_script_start;
        chosen_script_end = upload_script_end;        
    }

    const size_t upload_script_size = (chosen_script_end - chosen_script_start);

    /* Add file upload form and script which on execution sends a POST request to /upload */
    httpd_resp_send(req, (const char *)chosen_script_start, upload_script_size);

    return ESP_OK;
}
/* Handler to download a file kept on the server */
static esp_err_t download_get_handler(httpd_req_t *req)
{
    char filepath[FILE_PATH_MAX];
    FILE *fd = NULL;
    struct stat file_stat;

    const char *filename = get_path_from_uri(filepath, ((struct file_server_data *)req->user_ctx)->base_path,
                                             req->uri, sizeof(filepath));
    if (!filename) {
        ESP_LOGE(TAG, "Filename is too long");

可以使用电脑或者其他手机进行测试看看。现在的手机普通拥有外网访问检测机制,即默认不启用无法访问外部网站的热点。

不行,感觉这是一个现象,在手机连接成功并熄屏一段时间后重新打开锁屏继续使用,所有设备可以连接上热点,但都无法访问页面web页面,无论是手机还是电脑。熄屏时间大概十几分钟

从日志看息屏后重连热点,并访问网页,日志里只有手机连上热点,设备给手机分配 IP 的日志,没有看到手机访问 http server 的日志。你可以打开 LWIP 层 IP 层日志看下,看手机有没有访问设备。

现象是手机连接ap之后无法访问http server,也没有相关日志。
我现在发现是由于ap断开连接之后,http server占用的stack没有被清除,导致反复连接之后,给http server分配的stack被占满,从而无法访问,请问我该怎么办。

你怎么发现的?有日志吗?
