I wish there was some magical way to know why the connection isn’t working or to bribe the thing into working.  Obviously from this forum, and from dozens of issues in the TinyGSM library, a lot of people have trouble figuring out the right settings to get their board to connect.

And a new program to try to set it up in bypass to see if we can see what’s failing that way.  I’ve also posted this on GitHub here: https://github.com/EnviroDIY/ModularSensors/blob/master/tools/LTExBee_FirstConnectionBypass/LTExBee_FirstConnectionBypass.ino

Ugh; I thought it would work.  🙁

Two things to try.  First, try running the same thing but change your serial monitor settings to show you more of the output.  If you’re running the Arduino IDE, when you open the serial port monitor, use the drop-down at the bottom to select “Carriage return.”  (See screenshot.)  In PlatformIO, add this to the…[Read more]

The settings for the profile and the band mask should be saved on the module, so you should only need to set it up one time. But, if you’re using ModularSensors, you’ll see that a bunch of the set-up from the first-run sketch is copied in the set-up for the modem in the example sketches. So when using those examples, you’ll either need to delete…[Read more]

To use those commands exactly, you need to switch to bypass mode.

But, the proper equivalent of almost all of those commands area already being used anyway, so you don’t need to change much at all.

They are setting the profile to 1 just like I suggested (that’s the UMNOPROF).  Other than making that change, I think the only thing you need to…[Read more]

No, I don’t think those command suggestions from your IoT provider will help much.

The CPIN command checks if your SIM is locked by a pin number.  If your SIM provider didn’t mention it and give you the pin number, you shouldn’t need it.

The proper equivalent to theCREG command is already being used in the gsmModem.isNetworkConnected() command…[Read more]

1. If the SIM provider says you don’t have to do anything to activate the SIM, I’d trust them.
2. Yes, the “AS” command in the first run sketch does that. (line ~147)
3. If you’re using an XBee3 LTE-M it *only* supports LTE-M and LTE NB-IoT.  Since your provider doesn’t use NB-IoT, LTE-M will be the only possibility.  That first-run program you’re u…

Doh!  I’m sorry about the missing void statements.  That’s what happens when I write code on a discussion forum.  Good job fixing it!

The invalid library statements are probably because you put something that wasn’t a library into the library folder, even if it was just an empty folder.   The Arduino IDE thinks everything in that C:Us…[Read more]

I’m sorry, I should have read that more carefully.  That program is meant to be written to an ESP, not to a Mayfly.

Anyway, you should be able to do something like this:

#include <Arduino.h>

setup(){
    Serial.begin(115200);
    Serial1.begin(115200);
    delay(200);
 
    Serial.println("Changing ESP8266 baud, if necessary);…

Also, if the university requires any sort of two-set log in to the network (like, on a phone where you need to click ok on an “accept the terms” page) you won’t be able to do it.

I didn’t read through this in its entirety, but here’s something to start:  https://randomnerdtutorials.com/get-change-esp32-esp8266-mac-address-arduino/

To use ModularSensors to publish to a new endpoint, the “best” way to do it would be to create a new publisher, set the format there, and push it to the library.  There is documentation on how the ModularSensors library works here:  https://envirodiy.github.io/ModularSensors/index.html

As far as posting to SQL, you can’t do that directly, at l…[Read more]

I *finally* incorporated this when adding support for an InSitu RDO PRO-X.  I started working on it and it took me a while to find where I’d talked about it before.

@ckillen – That is awesome, and not too spendy either.

Yay!

Those temperature shouldn’t be a problem.  If I remember right, one of our first box iterations ended up acting like a little greenhouse and turning into an oven in the summer.

Could it be the amp-to-volt board that’s the problem instead of the sensor?  Do you have a second one you could test against?

The install guide for windows 10 is here:  https://www.ftdichip.com/Support/Documents/InstallGuides/AN_396%20FTDI%20Drivers%20Installation%20Guide%20for%20Windows%2010.pdf  Look at section 3.3 starting on page 9.

Remember that you need to be a computer administrator.  If you’re using a school/work laptop that you don’t have admin privileges fo…[Read more]

You absolutely must have administrative privileges to install drivers on Windows.  If you don’t, it might be the reason they failed to install with the Arduino program.

The “setup executable” linked in the comment column is probably the easiest way to install the drivers.  There is also a link to an installation guide there.  I’ve added sc…[Read more]

You need the VCP (virtual com port) drivers.  Scroll down just a little bit on the center of the page I linked and you should see a chart of operating systems and processor architectures.  Pick the one that matches your system.  If you’re running Windows and your computer isn’t terribly old, you probably have “x64 (64-bit)”.  If you’re not sur…[Read more]
