问题描述
我在一个自治GPS机器人项目中。一段时间后，当我运行以下代码时，esp32（devkit v1）重新启动，并且此过程不断重复。
I am on an Autonomous GPS robot project. When I am running the below code after some time the esp32(devkit v1) reboots and this goes on repeating.

与异步网络服务器结合使用是一个巨大的问题。我重写了〜15.000行的应用程序以摆脱字符串（也在使用的库中），从那时起不再进行任何重置和重新引导。希望这对您的项目有所帮助。
使用预定义的固定char数组，它们将进入堆栈并保持较低的堆损坏。使用诸如strcpy，strcat，itua / atoi之类的函数来构建消息或检索值。 br>
编辑：用固定的char数组示例替换String类
in combination with async webserver is a huge problem. I rewrote a ~15.000 lines application to get rid of strings (also in the used libraries) and since then no resets and reboots anymore. Hope this helps you in your project.
Use predifined fixed char arrays they will go to the stack and keep heap corruption low.Use functions like strcpy, strcat, itoa / atoi to build messages or retrieve values.
replace String class with fixed char arrays example
char numBuffer [16] ={'\0'} // For 15 chars and the null terminator
char latitude1 [32] ={'\0'} // For 31 chars and the null terminator
.... some code here ....
strcpy (latitude1 , "No values here");
//or
strcpy (latitude1 , "Value 1: ");
itoa (SomeIntDataNumber, numBuffer,10);
strcat (latitude1, numBuffer) // append the converted SomeIntDataNumber
使用memset，请确保您进行了适当的内存管理，并检查所使用的库是否大量使用了String类。一些库在静态环境中运行良好，在Web上下文中使用它们会使ESP崩溃。我不得不放弃一些库，或者至少在没有String类的情况下重写它们。
进一步阅读： https://hackingmajenkoblog.wordpress.com/2016/02/04/the-evils-of-arduino-strings/
最后提示：尝试注释掉String类的所有外观并将其替换为虚拟字符，然后重试代码。
One more thing if you use memset, make sure you do proper memory management, also check the used libraries for heavy use of String class. Some libs work in a static environment quite well, using them in a web context crashes the ESP. I had to ditch some libs or at least rewrite them without String class.
Further reading: https://hackingmajenkoblog.wordpress.com/2016/02/04/the-evils-of-arduino-strings/
Final Tip: Try to commenting out / replacing with dummy chars all appearancies of the String class and try the code again.
