我正在使用ESP32为自定义电路板编写固件。在蓝牙运行时尝试使用HTTPS连接服务器时出现以下错误。我相信我正在使用最新的IDF v3.0提交。我在测试之前就在esp-idf上运行了git pull。一旦出现问题，wifi将断开连接，无法重新连接。我已经通过论坛和试图寻找解决方案的问题进行梳理，但我很难过。也许我做错了什么，但我已经看到这些错误消息在问题跟踪器中弹出了几次其他错误。
到目前为止，我基本上已经完成了示例，所以主要使用蓝牙GATT服务器表示例，结合HTTPS请求示例。如果我在Wifi获得IP地址时将蓝牙设置为断开连接，则Https代码将按预期启动并且不会发生崩溃。有没有人遇到这个并有建议？

答案 0 :(得分：1)
这似乎与v3.1 beta之前的ESP-IDF版本不支持WiFi和蓝牙共存有关。我相信这两者一起使用了大多数板载RAM，那么mbed tls库需要的RAM远远多于可用的RAM。万一有人好奇，一种解决方法是在调用tls函数之前就断开并取消分配蓝牙，然后在完成后取消tls并重新初始化蓝牙。这很烦人，但可以。 esp-idf v3.1 beta应该已经解决了这个问题，但是我还没有进行测试。
