Wow!  What a great learning project.  It's my first adventure with platformio and I'm in love with this widget already.  Will be trolling the local plaza at lunch time tomorrow!

One question though - I cannot get the 'Upload SPIFFS' option to show when clicking on PlatformIO: Build button.  I did get it to load via the command "pio run -t uploadfs' ut I was hoping some one might know how to fix this.

In the meantime i'll continue to RTFM (http://docs.platformio.org/en/stable/userguide/cmd_run.html)

**NEVERMIND** 

Turns out the option is missing in PlatformIO IDE V1.4 (what i was running).  Updating to 1.6 (current) fixed it.

I noticed that between updates as well.  :)  Glad you got it going.

I am having a problem with the new firmware.

It compiles and loads into Wemos , but there is no wifi connection.

It just does not show. LED is constantly blinking on Wemos in like 800ms intervals.

I have two modules and both act the same. What could be wrong ?

And also I am planning on extending the range with an external antenna because the range is really poor.

Thanx

for some reason I cant login to the console no mather what password I set

did change it to cant touch this  ;)

Comment out these two lines to disable the authentication.  Then you can change it and then re-enable those lines.

```
if ( !request->authenticate ( username, password ) )
    return request->requestAuthentication();
```

Now that it works, I was thinking maybe put some Mc Hammers on it, couse you know you cant touch this, right :D

lol... nice.

A delayed stop button...  That follows with "stop...  Hammer time....."  :-). 

Thanks  for this Jaime; Saw it, loved it, had to build it, actually had the RA CD back when I was young.  Introduced my kids to it. Few hiccups with the Wemos D1 and USB drivers but solved with using a decent USB cable and google for the right win 7 x64 drivers.  Great little project.  Ive got limited understanding how it works, but am good at following instructions.  There is a bit of screwiness in reconnecting my android phone again and sometimes it doesnt load, but the idevices the rest of the family had got directed to the splash screen fine automatically.  Im thinking its getting a harry potter refresh and off to school with my daughter ;)

Im struggling with replacing the <audio tag a <video tag in index.html and adding an m.mp4 short mpeg 4 clip to data.  (Also struggling to paste into this window the code?)

After accept nothing happens.  Chrome on android phone. Should this work?

<video width="320" height="240" preload="auto" autoplay>

<source="m.mp4" type="video/mp4">

</video>

Oh awesome!  Yes... there is an issue with getting the captive portal helper to automatically popup on Android.  I'm working on fixing that so it works the same as it does on iOS devices. 

You'll have to modify the javascript used to start the audio and change it to start the video.  On a mobile device, you need a user interaction to play media.  That user interaction in this case is when the user clicks the "I Accept" button.

Actually, if you just use the same ID as the previous audio tag that should do the trick.

<video id="a" width="320" height="240" preload="auto">
<source="m.mp4" type="video/mp4">
</video>

That may work.

Hi

I am trying to build this project, but I have a bit of a pain compiling the code.

It gives me these errors :

text in red color:     /mobile-rr-master/src/mobile-rr.ino:443:13: error: 'rrsession' was not declared in this scope
text in yellow color : rrtotal++;
                       ^
text in red color:     /mobile-rr-master/src/mobile-rr.ino:444:13: error: 'rrtotal' was not declared in this scope
text in yellow color : IPAddress remoteIP = request->client()->remoteIP();
^
text in red color:     scons: *** [.pioenvs\d1_mini\src\tmp_ino_to.o]  Error 1

Could someone please help me fix this

I am new to programming, and have never programmed anything except some PIC micros.

System is win7 and I already added pio lib install 306 and pio lib install 64

Thank you.

Oops... sorry about that.  I accidentally mixed some code from the Enhanced Console branch where I changed the names of those variables.  I updated the code.  If you pull it now it should compile properly.

Well I actually managed to fix the problem, it works now. It is a great project. Actually the first I tried to replicate here on hackaday.io :D thanx to danrochman on github I added two lines of code and everything is working now. WIll be fun watching people on the beach trying to connect : D Thank you so mutch for this ;)

I'm trying to build it in PlatformIO and it's failing with the following error:
C:\Users\NamErehWon\.platformio\packages\framework-arduinoespressif\tools\sdk\lwip\include/lwip/i
p_addr.h:223:43: error: invalid cast from type 'IPAddress' to type 'u8_t* {aka unsigned char*}'
Any ideas?

same issue here.

I'm on Win 7x64. Tried it on three different machines. One with a fresh OS install.

Im on Windows 7 32bit...

I'm getting the same error. I've tried fresh installs of PlatformIO on OSX and Win7.

I posted the error over at platformio.org and user valeros was quick to find the solution.

Basically, you replace the line:

build_flags = -Wl,-Tesp8266.flash.4m.ld

with:

build_flags = -ULWIP_OPEN_SRC,-Wl,-Tesp8266.flash.4m.ld

in your platformio.ini file. This file is located in the folder you download from github (mobile-rr) and is in the root. Once I made this change, the project compiled without errors and I was able to then upload the SPIFFS image. I immediately connected to the resulting hotspot and was rickrolled right away. :)

I hope this helps. The topic over at platformio.org is here:

https://community.platformio.org/t/compile-error-with-ip-addr-h/581

Cheers,

Jason

Ah that did it. Also had to gzip the text-based files to get the SPIFFS upload to work. Time to head to some parks and broadcast some Free PokeMon Go Wifi.

Thanks for this, it works now! Oh, this is going to be fun!

Nice!  I posted a message there too and they referred me to your post with the solution.  :D  Thanks.  I've updated the source on github.

Change the build_flags to this  (remove the comma) to build a 4MB SPIFFS file system.

build_flags = -ULWIP_OPEN_SRC -Wl,-Tesp8266.flash.4m.ld

Oh yesss, dis gon b gud.

Hi Jamie

I've taken the advice on GZipping the appropriate files within the Data folder. I'm getting a 100% flash on both steps, but i'm not seeing any open access point.

I do however notice in your screen shots there are more files then whats contained withing the project provided. most notably the Clang file.

I have downloaded and installed Clang according to the directions given in the Atom IDE, but i'm not getting the same results.

Anything obvious i might have missed? I've never used Atom before, i'm much more familiar with the Arduino IDE.

My module does work i might add, I've re-flashed it with one of my own creations and it works right off the bat.

Some of those files that are shown in the screenshots were created by PlatformIO when initializing the project.  Try this.  Create a new project in PlatformIO and copy in the "src" and "data" folders from this project.  Then compare your platformio.ini to the one in this project and copy in the missing lines.  That should get you up and going.  If not, contact me via private message and we can chat on skype and I can help you get it going.

Great job - have got it working on a NodeMCU.

More importantly, the code is a great reference for a whole heap of things - such as spiffs which I have never used in the past.

It was a learning project for me.  I hope that it helps others out as well.  I'm still adding to it.

I bought a WeMos D1 Mini specifically for this project and I am happy to say it all worked! I love the idea and feel it could be combined in some way with my annoying machine (https://hackaday.io/project/4333-the-most-annoying-machine). Perhaps a step too far?!

Edit: I also want to mention the loading of the gif and MP3 was instant and as soon as I clicked "Accept" I was roll'd, just in case anyone still has doubts.

Great... glad you got it going.  :)

Looks fun. So far i have found all my 8266 have 512kb boo. Found some 2MB chips and tryed to replace but cant get it to work, cant get the baud to set to read the error. From what i can tell if u can set the spiffs to 1.5 itd be enough but need to make a custom ld file as only the curent ones only do 1mb / 1mb. trying to make it work off an sd card but running into SD.h not liking FS.h and ESPAsyncWebServer.h uses FS.h

Check the replies below. Excluding a few files will get it working without the console.

Although if you just gzip the HTML, Javascript and CSS files in the data folder it should fit in a 1MB SPIFFS image.

So got the salvaged 2MB 25x16avsig to work, came off old motherboard. Had to erase it, used esptool, also had to set flash mode to dout . esp11 lacks pins so used gpio1 (pin 2 in ide) for the piezo. Still trying to get it to work constantly likes to half load things and not always redirect. Will have to try upgrading a esp12. 

edited platformio.ini and changed

build_flags = -Wl,-Tesp8266.flash.2m.ld

added 

board_flash_mode = dout

Compressing worked well.

Hello,

I built this project and flashed into nodemcu board. It runs, creates wifi hotspot, I can see it lives in debug outputs via serial terminal, though every website is redirected to freewifi.com/index.htm and browser isn't able to connect, complaining about bad redirection. No Rick Eastley :-(

It behaves the same on two different devices, each with different OS and browser.

Any idea what is wrong here? Am I redirect-rolled?

The SPIFFS file system has not been uploaded to the ESP.  The page can't be found in the file system so it is redirecting (to the same page).

Oh, thanks - I really missed the upload SPIFFS image to nodeMCU board step.
By the way, at first I loaded image for Wemos D1 into nodeMCU and it didn't work. Recompiling image for NodeMCU failed with full filesystem error (smaller FLASH in the module?), so I had to remove the terminal stuff. So now I have the basic functionality (rickrolling), though no terminal - I can live with that. 

Hope this will be useful for somebody running into the same problems.

By the way - this is my first encounter with platformio (Atom) IDE. It was really painful.

Great... glad you got it working.

I have only used PlatformIO with my WeMos D1 mini.  I wasn't aware of any issues building for other configurations.  It would probably be best to include some more configurations in the "platformio.ini".  Then people could just uncomment the one that is for their board.

To get the Rick Roll count you could add another route similar to the "trigger" but it wouldn't increment the count.  That way you could hit the URL to figure out how many RRs you've doled out.  :)

Something like this added to the setupHTTPServer function should do the trick.

Then you'd just hit http://10.10.10.1/count to check the RR count.

------

httpd.on ( "/count", HTTP_GET, [] ( AsyncWebServerRequest * request )
{
request->send ( 200, "text/html", String ( rrcount ) ) ;
} );

------

I updated the source on github with this addition.

Will this sketch fit onto an ESP with 1MB Flash, or will I have to go shopping for an ESP-12F?

You need the space to fit all of the data files.

jaromir.sukuba suggested leaving out the console.  That would do the trick.

Just delete the following files from the data folder.

console.html
jquery-1.12.3.js
terminal.js
terminal.css

If you gzip the HTML, Javascript and CSS files it should fit in 1MB though.

Where's the firmware for this project?

There is a github link above.  "mobile-rr" :)

It works, great (fun) !

love it :D

Ahaha, Might have to dust off one of the idle ESPs and give this a go and power it on at the mall where people are always trying to mooch off the shops free wifi.
