As a beginner, I would suggest you pick either Atom OR VS Code – whichever one feels most intuitive to you – and use that one exclusively rather than attempting to flip back and forth between them.  Both editors will give you exactly the same tools for PlatformIO, but the menus and drop-downs and styling are different.  Rather than try to to r…[Read more]

Copying only an h file into your directory is *not* the proper way to install a library.  You should list the library in the “lib_deps” section of your platformio.ini and run the command pio lib install which should install the libraries listed in that section and their dependencies or you can install a single library with the command pio lib…[Read more]

pio lib uninstall xxx would mean “uninstall the library named xxx”.  You’d replace the “xxx” with the name of whatever library you’re trying to uninstall.  All of the documentation and examples use “xxx” meaning “replace this part with your own text”.

I put up screen shots with the locations of buttons to open a new terminal.

Huh. I don’t have any *good* suggestions, but he’s a hodgepodge of things to check :

You have to use bypass or USB direct to be able to use those commands, transparent/command mode won’t work. Can you get normal responses to other commands? (ie AT – OK; ATI – modem info)  Do you have your SIM card installed? The file being cleared is on the SIM…[Read more]

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…[Read more]

Delete lines 112-117 of the code I posted.

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?

😛  In double checking what the number would be for Verizon when it appears on the FPLMN, the very first google hit I got was an issue with someone else trying to force a Hologram SIM to use Verizon:  https://github.com/botletics/SIM7000-LTE-Shield/issues/163  Per that thread from just a few days ago, others suspect that Verizon has just very re…[Read more]

If you’re having trouble, you can try going into bypass and checking the operator profile directly on the u-blox:  send AT+UMNOPROF?  It should reply 3 (matching up with the CP value).  If for some weird reason it doesn’t, you can change it by first disconnecting from the network, changing the profile, and then restarting:  AT+CFUN=0 (OK) AT+UMNOPR…[Read more]

Also, I’m shamefully bad about notifying anyone when I’ve updated the libraries.

No worries!  I should have checked everything out on the Arduino IDE anyway.

If you have the same library installed in a global folder (ie userme_xx.platformiolibxxx) and the local project library dependency folder (project_xx.piolibdepsxxx) PlatformIO should select the local one to build that project and ignore the global installation.  Here’s the docs on the prioritization of installed libraries used at compile time:…[Read more]

Personally, I don’t install any libraries at all to my “global” folder in platformio.  (ie userme_xx.platformiolibxxx)  I always reclone the entire batch of libraries into the .piolibdepsxxx folder for each project.  That way I can recreate a specific program with the libraries just as they were when the program was used and can update at will fo…[Read more]

Do you have a carrier board that you can use to connect the XBee3 to the computer?  If so, then the easiest way is to use that.

Open XCTU and find the XBee3.  To type direct AT commands to the u-blox you need to be in bypass – get there by scroll down in XCTU to the “Serial Interfacing” section and change API Enable to “Bypass Mode [5].”  Cl…[Read more]

I got it to compile on the Arduino IDE, so there’s must be a tangle in your library structure.  Can you open the library folder (probably in my documents/arduino if you’re using windows) and look at your folders and make sure you only have one TinyGSM?  Can you open the TinyGSM folder and open “TinyGsmCommon.h” and check the version number?

Oh dear.  I forgot to test on the Arduino IDE.  I’ll start looking into it.

The Hologram dashboard should say “Verizon” in some way if it connected to that network.  The Hologram SIMs do work on Verizon, but they nearly always connect to AT&T in my experience.  There was a thread just a bit ago about setting the carrier profiles for the LTE-M XBee3’s , and for the time being we’ve decided that the default of “…[Read more]

Re-Wrote for you.  I didn’t even test if it compiles, but this should get you going with concurrent measurements:

/*The Sensor Orientation Index. This number is two when the sensor is upward facing, one when the sensor is downward facing, and zero
when orientation is undetermined.*/

#include <SDI12.h>
#include <SD.h>
#include <Wire.h>
#include…

Is your goal to read all of your sensors and write to your SD card as fast as you possibly can?  You could get faster readings by using concurrent sampling on the Decagons like this:  https://github.com/EnviroDIY/Arduino-SDI-12/blob/master/examples/k_concurrent_logger/k_concurrent_logger.ino

Well, setting the profile to ‘1’ might work fine for the long term; I really have no idea.  It just makes me a bit nervous.
