I am confused.
I saw there is a zip file with the files so I unzipped it into my project directory. I compared both platformio.ini files and they look the same. I opened the new – your- project and after platformio got done unpacking everything there were no errors
Something was different, but I know not what.

Now when I tell it to build I get the following error:
Library Manager: Installing git+https://github.com/ESP32Async/ESPAsyncWebServer.git
UserSideException: Please install Git client from https://git-scm.com/downloads
Where – what directory – does it go?

So pardon the moment of stupid.
I just did a standard Windows install, took all of the defaults.
I did have to re-start vscode, and made sure I updated my network details – did a load and after a short time it loaded and the WIFI connected,
Sara, I hope you forgive my entering all of this as problems, sometimes I feel like a problem magnet.
I just hope some of this will help others.
Thanks,
Hope it all goes smooth from here out! Smile

Hi.
Is everything working as expected now? Or do you still need help?
Regards,
Sara

Did you install the pioarduino extension as mentioned in the latest edition of the eBook?
Regards,
Sara

Yes I did install the pioarduino extension. It seems to be working well.
Next problem In – 1_2_Hello_World_WS_LITTLEFS
the program appears to be working – EXcept  there is nothing on the WEB page
It did connect – I did get a connection – in the address bar: Not Secure 192.168.1.242
But the page is blank
to get it I placed this in the blank address field: 192.168.1.242/
and the page blinked, the terninal display shows:

LittleFS mounted successfully
+++++++++++++++++++++++++
The data directory contains the correct files. The entire project directory was created by UN-zipping from the
zip file you provided in the book.
Question: How does the data Get into the LittleFS?
Does the initLittleFS do that?
 
Just an FYI about figures on pages 175 -177 all still show the project name as 1_2_Hello_World_WS_SPIFFS,
not 1_2_Hello_World_WS_LITTLEFS
Thanks

Hi.
You forgot to upload the filesystem image that uploas the files in the data folder. Please read carefully ALL the instructions. Everything is there. Don’t skip any pages.
Did you follow page 183? That shows how to upload the filesystem image.
 
Regards,
Sara

Well that works, I thought all that would happen when I used the -> button on the bottom pane. Is there a way, code, to load that filesystem data?

Where that favicon shows up took a bit of searching, For  some dumb reason  I expected it to be ON the WEB page, not in the TAB with the Title.

I do not see it at all on my phone- the title is not there either – just the IP in the address bar and the actual web page

Rather than modifying the same project over for each unit, each one is a new project.

I am using the same esp32doit-devkit-v1 [env] and board in each and they all use the same include files,

does each environment have a copy or is platformio smart enough to only keep one copy?

If not, how can we save space by setting up the includes so there is only one copy when they are the same?

Note: because all of them use the same named – esp32doit-devkit-v1- it was difficult to tell when pioarduino was using the correct data directory for the image. I built and uploaded the wrong one at least two times.

Just another observation, If you connect to the server from more than one device. The WEB server only send a response to the one requesting a change. In other words, if browser A clicks the off button, browser B does not show the change even if you refresh B.

Hi.
Which web browser are you using?
Because the second browser should change after a refresh.
 
Regards,
Sara

Firefox on my Windows10 desktop and one NON iphone and Chrome on 2 other NON iphones Some of which are old Samsung (all Androids)
 
You didn’t answer my question about whether all of the projects use or can use 1 library for the includes with platform IO – one of my objectives for this course is to learn more about Platformio.
Thanks for putting up with me.
Dave

Hi.
The examples were tested using Google Chrome and Safari on iPhone, and everything worked as expected.
Make sure to clear the cache or hard refresh your web browser between each project, because sometimes it will cache the HTML and you may not get the expected result.
 
Each project has its environment. The libraries need to be loaded for each specific project.
Regards,
Sara
