Editing Variable UUIDs

Delete them.

It looks like you’re using the Arduino IDE. Managing multiple libraries for the Arduino IDE is NOT easy – it is quite a hassle. Have you installed all the libraries following the instructions here: https://github.com/EnviroDIY/Libraries#installing-libraries-in-the-arduinocc-ide? Have installed them more than one time? When you open your Arduino library folder (likely documents/Arduino/libraries), do you see only one folder for each library. If you see multiple folders with the same names, (ie, EnableInterrupt and EnableInterrupt (2) ) then you do have multiple copies of libraries and must remove the extras. If you have not done any modification of you libraries and you haven’t programmed other boards in a way that you need to be able to reproduce exactly, I would start fresh by deleting everything in your Arduino/libraries folder and reinstalling them all following the directions I linked above. If you’ve modified any other library or you have other programs depending on the exact versions of your installed libraries, you’re going to have to manually go through them and delete the conflicting versions and install anything missing. All of the dependencies for ModularSensors are listed here: https://github.com/EnviroDIY/ModularSensors/wiki/Library-Dependencies (and of course ModularSensors itself is required).

This difficult in managing libraries is the primary reason I would never recommend the Arduino IDE. PlatformIO makes this management much easier, even though it might seem scarier to beginners at the start.

The OBS3+ treats the low range and high range turbidity as if they’re two completely different things. So on Monitor My Watershed you actually have to create two different variables, one for each of the high and low range, just like you would separate temperature and depth from a CTD. I *strongly* recommend you add something to the notes field for each to remind you which is which. Once you’ve create two different variables on Monitor My Watershed, it will give you two different UUID’s.

Here’s another site with the turbidity set up for both high and low range: http://data.envirodiy.org/sites/PKCV7S/

If you really want to have only one turbidity field streaming, you can either pick one of the two or create a calculated variable that picks between the two depending on the turbidity. For most of our sites, we’ve decided to just stream the two separately.

Posting here is really the best way.  You can attach the output as a text file.

That’s a lot of compiler errors!

Could you post your program (“sketch_jan07a.ino”)?  I’m guessing based on the errors that there might be a stray quotation mark or a missing semicolon somewhere that’s throwing the whole thing off.

It looks like you have also some of the libraries installed multiple times and I’m guessing some might not be installed.  Did I mention that library management with the Arduino IDE isn’t easy?  That’s it’s biggest downside.  ModularSensors has so many dependencies that managing them gets pretty painful pretty fast with the Arduino IDE.  (Sorry!)  But it is definitely doable!

Can you check your library folder like I described back in November?  Again, if you’ve written programs before that you want to work again exactly as they did in the past, you’ll have to crawl through each library checking for versions, but if not you might as well delete them all and start over.

It looks like when you created your sketch, instead of starting with a completely empty file you pasted your code into the middle of the Arduino IDE’s placeholder code.  So there are chunks of that at the beginning and end which you need to remove.

From the beginning, delete this :

void setup() { // put your setup code here, to run once: } void loop() { // put your main code here, to run repeatedly:

From the end, delete this :

} // ========================================================================== // Main loop function // ==========================================================================

The last line in your code should be a closing curly brace.

If you are still getting library compiler errors after fixing your sketch, I would strongly prefer to guide you through using PlatformIO. It really is easier, even though it feels much more “programmer” then the more “hobbiest” Arduino IDE.

Very , very briefly:

1. Open the “PlatformIO home”, and create a new project
2. After your project is created, delete the contents of the new platformio.ini file and replace them with the contents of the same file from the folder where you copied your code from on GitHub
3. Delete the contents of src/main.cpp and replace it with your corrected sketch
4. Open the PlatformIO menu (looks like a bug) and select “build.” it should download the proper versions of all the libraries and their dependencies (which might lake a few minutes ) and then compile.

If you really, really want to use the Arduino IDE and you can’t get it to compile there, please post a screen shot of your libraries folder for the Arduino IDE (probably in documents/Arduino/libraries or something similar). Make sure the screen shot shows everything. Also go to the Arduino IDE’s library tool and list out all the libraries and versions it shows are installed. Post the screen shot , your corrected code , and the full error log your getting so I can try to figure out where to help next.

The path to your Python.exe will likely be:
C:\Users\<your-username>\AppData\Local\Programs\Python\Python38

If you don’t find it there, you could try the method described here:

Hmm, are you able to successfully open the python interpreter at that location? E.g., from Windows command line, enter

I had some issues with Python when switching to PlatformIO from the Arduino IDE.

I had an older version of python installed, so I thought I would be slick and update before installing Visual Code and the PlatfromIO plugin. That is where I messed up and PlatformIO was pissed.
What alleviated my issues were completely uninstalling all python and Visual Code bits, and reinstalling them together. When you download and install the PlatformIO plugin it looks for the path to the python.exe. If it can’t find it, or you tell it incorrectly, and it is crazy picky on the verbiage, it will become upset and provide you a link to go download it. Do this, and follow the prompts. Make sure you check the box to add python to the path! this is critical.
Ensure that your path is correct within PlatformIO, but if you let PlatfromIO take the wheel it will remember where it was saved.
Having only ever played with the Arduino IDE, I too struggled to get PlatfromIO going. But it is superior and I probably won’t go back to the Arduino IDE.

Good luck!

The DRWI_CitSci.ino, once corrected, is what will go in the src/main.cpp location correct?

Correct.  🙂

The platformio.ini you need is here:  https://github.com/EnviroDIY/ModularSensors/tree/master/examples/DRWI_CitSci

I’ve had problems with the python path before, not just with platformio, but with other programs as well.  I’ve had to uninstall and re-installed all of python and anaconda several times over the years.  It’s not been a huge number of times, but I haven’t ever tracked down the reason it got screwy.  I’ve kind-of accepted that as an annoyance of python.

The git problem is probably another “path” issue.  Did you add git to your “path” when you installed it?  I don’t remember if the installer gives you the option.

Try checking your path and adding the directory where git installed to it.  The git executable (git.exe) is probable installed in “C:\Program Files\Git\bin”  Here are some instructions for adding a directory to the path:  https://helpdeskgeek.com/windows-10/add-windows-path-environment-variable/

Hm.  Did you restart VSCode after changing the path?  Can you open up a new terminal and successfully run git?

I’m sorry; I know dealing with these setup things can be really frustrating.  I really appreciate you working through it on the forum where it might be able to help someone else, too.  It’s been such a long time since I first started out that I forget the beginning steps.

I’m sorry!  It looks like it somehow missed the dependencies in the install.  Try running the command pio lib install EnviroDIY_ModularSensors

Huh.  It’s an “access is denied” error.  I’m guessing two processes tried to write to the same temporary folder – the automatic “check for new libraries in the library folder” process and the manual install probably collided.  Did you get the same error multiple times after exiting and reopening?

There’s probably a missing semi-colon or brace in your program code somewhere right above line 215.

Check first where you pasted in the UUID’s.  Each UUID should be enclosed with quotation marks, there should be a semicolon after both the registration token and the sampling feature and a comma after each UUID/variable in the UUID list.

You can also check for matching braces by clicking each starting brace/parenthesis.  VSCode should highlight its corresponding closing brace so you can see if they’re closed appropriately.

In line 239/240 you’re missing the opening brace of the setup function.  It should be void setup() { with that opening curly brace.  You can put the curly brace right after the parenthesis on line 239 or by itself on line 240.

Missing braces and semi-colons are such a pain.  The error messages they usually cause don’t help much.

Also, your code is missing the “loop()” function – it will set everything up and then do nothing.  You probably want to add this loop (just paste it at the end of your current code):

Well, it really is that “easy.”  “All” you do have to do is create a new project/program, make sure it’s completely blank, copy and paste the example from GitHub into your new project, select precisely each UUID and delete the example junk text, select and copy the real UUID from the MonitorMW webpage and paste it in exactly the place you removed the example from, repeat that 7+ times, install all the libraries correctly, and compile and flash your Mayfly.  That’s it.

It just that it’s actually kind-of tricky to make sure you’ve selected exactly the right text when you’re doing all the copy-pasting and if you didn’t remember to start with something blank at the beginning things get mixed up and then you have to start deleting and fixing and then you end up in this mess.

Looking back at the old threads.. I told you to delete the loop because you had other junk after the end of the loop and I went back too many line.  Doh.  Totally my fault.

After adding the opening brace I mentioned in line 239 and adding the loop at the very end, after everything else, your program compiles fine for me.  Did you by chance accidentally add both an opening and closing brace instead of just the opening one?  The editor helpfully adds the closing brace for you when you type the opening one.

Here’s your program that compiled correctly for me.

You didn’t manage to connect to the internet for the clock sync.  I’m not sure why that happened.

The modem values won’t update in sensor testing mode and they’re always updated at the *prior* internet connection.  Since you didn’t connect successfully for the clock sync, they didn’t update.

Working on it right now for you.  It will be a library update.  The lack of modem update in sensor testing mode was an oversight; I want it to be there automatically.

I’ve pushed what I think should fix the testing mode to the develop branch of the ModularSensors library, but I haven’t actually tested it myself yet.

I’ll see if I can get it tested tomorrow and then pushed to the master branch.

I’m so sorry.  I haven’t tested it yet.

I’m sorry.  I finally fixed pushed what I think should be the changes needed to the develop branch, but I still haven’t programmed an actual board to test it.  You should be able to test it yourself by listing the develop branch from git in your dependencies.  (In the platformio.ini replace “ModularSensors” with https://github.com/EnviroDIY/ModularSensors.git#develop)

This everyone being home all the time situation is brutal.  Anyone doing well with it  is clearly a lot more disciplined and organized than I am.

I just added another fix for the XBee wifi and the modem-measured battery voltage.  Have you been able to get it to work for you?
