bcn_timout造成重启

[ninesuntj]

麻烦请教一个问题，我现在用的esp-idf是最新的版本，用的模块是ESP32-WROOM,我的应用同时支持蓝牙和OTA升级，主要的任务是通过http的post请求一个服务器然后取回数据，现在的工作模式是发送post请求，然后得到请求回复，解析数据以后一秒钟发送下一次请求。我的程序结构和peform stream read 类似：大概是如下一个结构：
while(1)
{
esp_http_client_init()
esp_http_client_open();
esp_http_client_write();
esp_http_client_fetch_headers()
esp_http_client_read（）
解析数据
esp_http_client_close();
esp_http_client_cleanup();
}
这样反复循环，开始能够正常收到数据循环，大概120次左右esp32就会重启，出现的log输出：

我在网上搜索一下，发现可能是内存不够了，造成这个bcn_timout,ap_probe_send_start错误，现在的问题是我一秒钟post一次，这样重启的太频繁了，请问有什么建议可以改善重启？

[ESP_Gargamel]

1、你在 while 循环里，加一个 esp_get_free_heap_size 来获取剩余内存，看内存是否有在持续减少；
2、你可以通过 menuconfig，把 WiFi 的 debug log 放开；
3、如果不使用蓝牙，是否有问题？
4、换个路由是否有问题？
5、能否用最新的 release 版本做测试？master 版本未必是最稳定的。

[ninesuntj]

按照您的建议，我关闭了蓝牙，使能了wifi debug,增加了esp_get_free_internal_heap_size，根据 占用堆的大小，输出也不是一直增长的，是有变化的，在bcn_timout后log如下：

至于路由器曾经在多个路由器上试过，结果都是一样的，另外我试过用http_client的测试程序，把结构程序改成和我应用相似的，在同样的路由器和相同软件版本下可以稳定运行。出现bcn_timout的概率很小，基本没有。由此应该可以排除路由器的影响，软件的版本我会尽快用一个release版测试一下。
谢谢！

请问解决了吗 是怎么解决的呢
