I’m sorry.  No, I don’t think it’s an issue with the battery or the SIM.

When you were running in Transparent, the XBee3 just didn’t register an internet connection.  They just do that sometimes – refuse to acknowledge they are registered on the network.  Sometimes switching from transparent to bypass and back to transparent “magically” fixes th…[Read more]

You are exactly 1 commit behind for TinyGSM.  Try again.  Have you maybe installed TinyGSM to your “global” library registry instead of your local one?  You might need to do a “pio lib -g update” (-g flag for global).  Otherwise you can navigate directly to into the folder and use git to update:  cd .piolibdepsmayflyTinyGSM followed by git pull.

Ah ha!  Can you check which version of SensorModbusMaster you have?  Is it by chance 0.6.7 or lower?  There’s was nasty bug that would cause non-avr boards to crash if the DE/RE pin was set and debugging was turned off.  The bug was only caught and fixed by @neilh about a month ago.  You can get the current version here:  https…[Read more]

@ensign and others (Rachel Johnson, Matt Gisondi, David Bressler, @hicks and a few more) have put a lot of work into that manual!

What?? You haven’t read all the docs??  Actually, I don’t remember how well documented the build flags are.  Writing good documentation is hard.

Are you using transparent or bypass?  You can remove the build flags for whatever you’re not using.  You also don’t need the MQTT flag, it only applies to ThingSpeak (or anything else MQTT).  You also…[Read more]

It would help me to help you if you would be more verbose and detailed in your responses.

You didn’t answer whether you, yourself, had every succeeded in communicating with the sensor in any other way.  I assume that means no.

You’re using example code that includes code for a small screen?  Do you have one?  If not, it might be easier to use th…[Read more]

@ayechan – do you have a specific problem or are you looking for general instructions?  If you have a specific problem, please create a new topic with a detailed description of your setup and problem.

If you are looking for instructions, start by reading the sensor manual provided by Yosemitech.  If possible, connect the sensor to you computer u…[Read more]

That configuration looks good to me.  Let me know if you see any bugs I can smash.

Yes, that’s what it should have done.  I don’t see any obvious reason why it wouldn’t have, other than that it clearly didn’t.  The single battery measurement was on the low side (only 3.6) so it is possible that your battery just died.

I made an issue for myself to fix this: https://github.com/EnviroDIY/ModularSensors/issues/304  Unfortunately, that doesn’t give you back lost data.

Oh.  Oops.

The data was probably rejected because of the timestamp.  The clock resets itself to 2000-01-01T00:00:00 – but then ModularSensors applied a negative offset to it assuming you wanted the file to be in UTC-6 with an RTC set in UTC.   That caused a weird rollover (roll-under?) giving you a timestamp of 2000-01-01 252:211:00.  Moni…[Read more]

I didn’t try running it, but there’s nothing that jumps out at me in a very quick glance through the code.  Did the SD card have data on it?

That does seem worthy of a new thread; those are the Bee’s we’re using so I’m more familiar with them.  They’re easier for us to get (no international shipping), similar in price, have carrier certification, and have a secondary processor that takes care of the baud rate trouble.

I don’t think we’ve had any yet that were DOA, but we have managed…[Read more]

Was anything recorded on the SD card?

If you remove both the coin battery and the mayfly loses power, even for an instant, the clock will reset to Jan 1, 2000 0:00:00.

The coin battery isn’t necessary if there’s another power supply, but it’s very convenient to power the clock with its own battery so that you don’t have to reset the clock every time you turn the Mayfly off.  The…[Read more]

As for T-Mobile’s 2G, the most recent I’ve found says no guarantee past the end of this year.  A while ago they were saying that they would maintain the same coverage area for 2G up until the sunset, but we keep having more sites without coverage.

I’m sorry!  The SIM800 definitely has quirks, but it’s better than this.  We have had better luck with the Mayfly and Digi LTE XBee3’s than you have had with the UBee, but I’ve spent a lot of time tweaking things to figure out what works.

It’s funny, we were on a phone call at one point with a group at Oregon State that was just beginning to l…[Read more]

I’m sorry, but you keep saying things that are unclear and incomplete which makes it very frustrating for me in trying to help you. You seem to know very little about what you have so it’s difficult for me to believe that you do have correct wiring and code.

Do you have or have you read the manual from Yosemitch for your sensor and do you…[Read more]

Are you using Arduino core on your ESP8266 or are you using NodeMCU Lua? They are completely different firmwares; Arduino core uses cpp and has many libraries that parallel functionality to an AVR Arduino board like the Arduino Uno. NodeMCU uses Lua script.

I use softwareserial and ive heard that it work but dont really know.

There is a…[Read more]

I am so very unimpressed with the SARA R410. It does not deserve its name.
