setup() code for wifiserver and webserver works fine on ESP8266 and appearently also is fine for ESP32, but then it crashes when creating the website.
What is wrong with the website code?

Client may be null in loop is the only thing I can see. You will need to decide the backtrace to know for certain where the null dereference is happening.

tbh, I do not understand.
The code is working for esp8266 since many years and is also Arduino Wifi shield compatible, so what shall I do exactly?
which would be the correct esp32 code for building the website?
dsyleixa
on 15 Jun 2020
repeating how it works on 8266 will not help you much. decoding the issue with the ExceptionDecoder might actually help. Link and instructions were in the issue template that you edited. Also can be found in the readme. And since you so much "works on 8266 for ages" 8266 uses the same exception decoder.
me-no-dev
on 15 Jun 2020
I don't know how to do that decoding with the ExceptionDecoder.
OTOH, for esp8266 there is no issue and never was, there all the code runs like a charm, so I never needed the ExceptionDecoder so far.
dsyleixa
on 15 Jun 2020
then maybe good time to learn to use it if you want help.
me-no-dev
on 15 Jun 2020
I do not understand that, that is way too complicated https://github.com/me-no-dev/EspExceptionDecoder - any help highly appreciated!
dsyleixa
on 15 Jun 2020
ok, let me try to say it more clear.
We can not give you any help unless you decode your backtraces. There are tutorials, youtube videos and more on how to install and use the exception decoder. Also in your code you did not show handleRoot().
me-no-dev
on 15 Jun 2020
yes, a c+p error.
I meanwhile updated the code which now compiles fine.
dsyleixa
on 15 Jun 2020
PS,
after installing the decoder I get no elf trace or whatever
dsyleixa
on 15 Jun 2020
you need to paste the backtrace into the window... and the sketch to be compiled and running. Did you look at any video?
me-no-dev
on 15 Jun 2020
I don't get a window, just a file to select (which is not existent).
I also don't understand English well (I am using Google translator).
Can please test this thing anyone who is experienced?
dsyleixa
on 15 Jun 2020
You open the sketch in Arduino IDE, you compile and upload the sketch to the board, then open the serial monitor so you can receive the error. Now open the exception decoder, it will not ask you for file, paste the error in the top half and you will get the result.
me-no-dev
on 15 Jun 2020
I did all that, I created a new empty file, then I opened that file, then I pasted the code, but I don't get a result.
dsyleixa
on 15 Jun 2020
In your first post, there is a debug part. Guru Meditation Error....
The end is rebooting and date. Before that ther is a line with Backtrace: .....
That line have to be copied to the expectiondecoder including the "Backtrace:" , while your board connected and running the code that cause the error.
usane1
on 15 Jun 2020
Btw, probably it is the HTTPClient related issue that cause a lot of problem in 1.0.3 and 1.0.4 core.
Read #4039 and #3347 .
usane1
on 15 Jun 2020
yes, I copied the line Backtrace, but got no result.
I also tried 1.0.2, same crash.
What is the solution to the Guru crash problem?
dsyleixa

What is the solution to the Guru crash problem?
Find and fix issue.
chegewara
on 15 Jun 2020
@dsyleixa you must compile your sketch in the same ardunio ide as you are using the backtrace decoder. Copy/paste the trace from the serial monitor in the ide into the trace window and it should produce a meaningful decode output. The decoder has a required dependency on the binary produced by the ide in order to decode the trace.
atanisoft
on 15 Jun 2020
yes, I did that, but no result.

Then you probably not installed correctly the decoder. It gives me result if i put your backtrace to my decoder but thats not gives the good result because i havent got your code, and i have different operating system, file system etc...
usane1
on 15 Jun 2020
Then I don't think we can help narrow down the cause for the failure if the decoding is not happening. From a very quick read of the code it doesn't look like there is any error checking being done in handleWebsite() which would include checking that wifiserver.available() returned a valid client object (if none are available it can return nullptr).
Also assigning script at the end of that method is not necessary. The variable will go out of scope and be cleaned up automatically upon exit from the function. You could also improve the function a bit by directly calling client.print() directly
atanisoft
on 15 Jun 2020
You may dislike my answer, but its only correct.
There is tens of tens situations that can cause Guru crash. My bet is you are trying to access not initialized variable.

chegewara, if you cannot provide a reasonable fix, please troll somewhere else.

@dsyleixa he isn't trolling. He is staying fact. There are many ways to encounter such crashes and often times they are due to simple mistakes
atanisoft

I do not understand what to do now, I am just an Arduino hobby-user.
Can you please try my code and see if you can find the reason?
Or provide a code like mine which is working?

No, because you will never learn to use backtrace decoder and will get back here with every single crash.

@dsyleixa esp32 is not the same as esp8266 and it never will be.
You can try adjusting your handleWebsite() to look like this:
void handleWebsite() {
WiFiClient client = wifiserver.available();
if (!client) {
return;
}
String request = client.readStringUntil('\r');
This checks that the client object that was returned from the server listener is valid (ie: connected to something) and if not it gets out of the method before trying to use it.
As for the other suggestion you can do something like this directly and save yourself a lot of memory on the stack:
client.println("HTTP/1.1 200 OK");
client.println("Content-Type: text/html");
client.println(""); // blank newline after header data
We can't test your code because github has not private messaging. If you can send your code an other way to me, i give it a test, but today i only have about 30 min then i go.

dsyleixa
on 15 Jun 2020
I applied your changes, now no crashes but also still no website generated:
well, it looks like it hasn't accepted a connection. You may need to turn up the core debug log level to see what might be going on in the underlying layers. Set your board type to the ESP32 Dev board (should be one of the first ones in the list) and you will find a core debug log level menu option, set it to DEBUG and reflash the sketch.
@usane1 has decoded the backtrace and it points to using a null client object which you have a fix for now.

@atanisoft:

dsyleixa
on 15 Jun 2020
what is a null client object and how to use that?
The listener did not have a connected client so it defaulted to return a null value. It is always a good idea to validate the return values from APIs to ensure they did not report an error condition (which this could be taken as).

I still don't understand.
All I see is my old code line
WiFiClient client = server.available();
What is the null client code there?
dsyleixa
on 15 Jun 2020
Chekt the line in the example code:
if(client){
....
}
That means if it doesnt run to dis loop then nothing connected to the ESP, that means nullclient.

That only solve the Meditation error, but doesnt't solve why the client cannot connect to the ESP, that what is need to figure out.

Just a quick thought... you are connecting to port 8080 and not 8081 correct? I see you have a WebServer instance configured for 8081 and the handlers are stubbed off to not do anything which could give you the results you are seeing. But if you are connecting to 8081 I would expect it to work, perhaps you can add some Serial.println() statements in your handleWebsite() method to see where it is getting to?
atanisoft
on 15 Jun 2020
yes, ports 8080 for wifiserver and 8081 for webserver work fine with esp8266:
WiFiServer wifiserver(8080);
WebServer webserver(8081);
I will add some prints.

PS,
also changing this didn't help:
//WiFi.config(this_ip, gateway, subnet, gateway, gateway); // dns = gateway
WiFi.config(this_ip,gateway,gateway,subnet);

what do you mean by "connect to 8081"?
How should I do that?

That is the port that the WebServer instance is using, though you won't get a webpage from it since the handlers are stubbed off in the code you have posted.
update:
after many seconds or even a couple of minutes I suddenly got intermediately again:
You will need to decode the new backtrace to get further on this.

I still don't get a result if I c+p the backtrace into the Exception Decoder window, no reaction then.

@dsyleixa the only troll here is you. You refuse to comply to the norms for posting issues. Refuse to take some time and get the exception decoder working. Insulting fellow users. Should I continue? Novice, not novice, does not matter. There are minimum requirements for you to read and follow instructions.
I am closing this issue. Do not want another 60+ emails on this.
