Zip library problem

[UKHeliBob]

Please follow the advice given in the link below when posting code, in particular the section entitled 'Posting code and common code problems'

Use code tags (the < CODE/ > icon above the compose window) to make it easier to read and copy for examination

https://forum.arduino.cc/t/how-to-get-the-best-out-of-this-forum

Please post your full sketch, using code tags when you do

Posting your code using code tags prevents parts of it being interpreted as HTML coding and makes it easier to copy for examination

In my experience the easiest way to tidy up the code and add the code tags is as follows

Start by tidying up your code by using Tools/Auto Format in the IDE to make it easier to read. Then use Edit/Copy for Forum and paste what was copied in a new reply. Code tags will have been added to the code to make it easy to read in the forum thus making it easier to provide help.

It is also helpful to post error messages in code tags as it makes it easier to scroll through them and copy them for examination

what is wrong with post #10 ? I used the tags, and it is a complete sketch.
error

webpage.h: No such file or directory

@tom321

what is wrong with post #10 ?

Post #10 is perfect. But then in post #19 you posted a screenshot of your code. Posting pictures of text is not helpful.

@tom321

error

webpage.h: No such file or directory

That error is expected from the code in your screenshot:

Line 19 has the incorrect syntax, which will cause the error.

You have the correct syntax on line 18, but that line is commented out.

Delete line 19 from your sketch, uncomment line 18, and then try compiling again.

[tom321]

I was trying both cases = error the same

[ptillisch]

I'm going to ask you to provide the full output from a compilation.

This procedure is not intended to solve the problem. The purpose is to gather more information.

---

Please do this:

1. Open the sketch in Arduino IDE.
2. Make the changes to the sketch code that I described in my previous reply.
3. Select File > Preferences... (or Arduino > Settings... for macOS users) from the Arduino IDE menus.
   The "Preferences" dialog will open.
4. Uncheck the box next to "Show verbose output during: > ☑ compilation" in the "Preferences" dialog.
5. Click the "OK" button.
   The "Preferences" dialog will close.
6. Select Sketch > Verify/Compile from the Arduino IDE menus.
7. After the compilation fails you'll see a button on the right side of the orange bar in Arduino IDE: Copy error messages. Click that button.
8. Open a reply here on this forum topic by clicking the "Reply" button.
9. Click the <CODE/> icon on the post composer toolbar.
   This will add the forum's code block markup (```) to your reply to make sure the error messages are correctly formatted.
   
   
10. Press the Ctrl+V keyboard shortcut (Command+V for macOS users).
    This will paste the compilation output into the code block.
11. Move the cursor outside of the code block markup before you add any additional text to your reply.
12. Click the "Reply" button to publish the post.

---

In case the output is longer than the forum software will allow to be added to a post, you can instead save it to a .txt file and then attach that file to a reply here.

Click here for attachment instructions

1. Open any text editor program.
2. Paste the copied output into the text editor.
3. Save the file in .txt format.
4. Open a reply here on this forum topic by clicking the "Reply" button.
5. Click the "Upload" icon () on the post composer toolbar:
   
   
   
   The "Open" dialog will open.
6. Select the .txt file you saved from the "Open" dialog.
7. Click the "Open" button.
   The dialog will close.
8. Click the "Reply" button to publish the post.

Alternatively, instead of using the "Upload" icon on the post composer toolbar as described in steps (5) - (7) above, you can simply drag and drop the .txt file onto the post composer field to attach it.

That is unexpected. Please make a ZIP from the "wifi_voltmeter" sketch folder and attach the ZIP file to a reply here on the forum topic. Maybe we will be able to spot the problem by looking at the sketch files.

That is not what I asked for.

Please do this:

1. Open the sketch in Arduino IDE.
2. Select Sketch > Show Sketch Folder from the Arduino IDE menus.
   The wifi_voltmeter sketch folder will open in Windows File Explorer.
3. Right-click on the wifi_voltmeter folder in File Explorer.
   A context menu will open.
4. Select "Show more options" from the menu.
   Another context menu will open.
5. Select Send to > Compressed (zipped) folder from the menu.

A ZIP file will now be created which contains the contents of the wifi_voltmeter sketch folder. Attach that ZIP file to a reply on this forum topic.

OK, great. I see the problem now. You named the file webpage.h.ino, not webpage.h. Arduino IDE 1.x hides the .ino file extension, so this is why it appears as though the file is correctly named when looking at the tabs in the IDE.

Use Windows File Explorer to rename the file from webpage.h.ino to webpage.h and then try compiling the sketch again.

File Explorer is configured to hide known file extensions by default, so depending on the configuration of your Windows you might not see the .ino file extension in File Explorer until after you change the setting.

error the same

As I said, you need to change the default configuration of File Explorer:

1. Open File Explorer.
2. Click View on the File Explorer toolbar.
   A menu will open.
3. Select Show > File name extensions from the menu.

You will now see the full filename of webpage.h.ino, and be able to rename the file to the correct name webpage.h.

I had a short look into the video you linked. There is a lot more wrong in your sketch.
Where did you get the code from? I don't think you typed it by hand from the video?

Your main .ino file contains both - the code for wifi_voltmeter.ino and the code for the webpage.h file

@tom321

void loop() 
{
  webSocket.loop(); server.handleClient();

  String POTvalString = String(float(analogRead(A0))/1170.0);
  JSONtxt = "{\"POT\":\""+POTvalString+"\"}";
  webSocket.broadcastTXT(JSONtxt);
}

Header file "webpage.h":  << This is the start of the webpage.h file. 
The following code must not be in the .ino but in webpage.h file

//=====================
//HTML code for webpage
//=====================
const char webpageCont[] PROGMEM = 
...

And your webpage.h file contains something completely different, that does not fit to your sketch.

You must split your current .ino file to a .ino and a .h accordingly

I fixed what you have suggested, no errors = THANKS

But device does not even trying to connect to WiFi network

[ptillisch]

The sketch program is configured to do serial communication at 9600 baud:

@tom321

  Serial.begin(9600);

but you have the Serial Monitor configured for 115200 baud. So this means you won't see any of the serial data sent from the sketch program in Serial Monitor. The reason you see some content in Serial Monitor is because the boot ROM on the ESP32 prints some diagnostic information at 115200 baud on startup.

So select "9600 baud" from the menu at the bottom of the Serial Monitor window and you should now see some output from the sketch program. Even in the worst case scenario where the board is not able to connect to the Wi-Fi access point for some reason, you should still see something like this:

......

(the program periodically prints . characters as an indicator that it is trying to connect to the access point)

@ptillisch

So select "9600 baud" from the menu at the bottom of the Serial Monitor window

I think a better solution would be to change the baudrate in the sketch to 115200 - so you see both: the output of the boot ROM and the output of the sketch.

[tom321]

  Serial.begin(115200);

Did you set ssid and password in the sketch according to your WiFi Network?
