What is the battery voltage that your Mayfly is recording in your data file?  We’ve had a few random failures of a mosfet on the board that will cause the Mayfly to read the incoming Lipo or USB voltage as being much lower than it really is (see this post: https://www.envirodiy.org/topic/innacurate-lipo-battery-voltage-data/).   Your logger co…[Read more]

I just get 1byte but sometimes i get 2, the read too 0x03. So i dont really know whats wrong now lol.

OK. What’s perplexing to me about this one is that Jake’s been able to reinstall the same LTEBee and SIM back into the “old” Mayfly (the one we’re trying to swap out), and it will connect and upload data successfully.

Thanks for continuing to sleuth out all the LTEBee issues.

Thank you very much! I got it to connect but reciving 1 bytes because of (CRC of response is not correct!)

Probably just me doing something wrong with delays!

You might try using a new SIM card or a new LTEBee module.  We’ve had several of them stop working recently for no reason at all.  Sometimes using a brand new SIM card will fix the problem, but other times it requires using a new LTEbee module.  We haven’t determined the cause of the failure yet, nor a solution to get them working again.

Well, we’re still unable to connect to the internet. We were using transparent mode on the XBee3, but I tried switching to bypass, and still no luck. Then, thinking that the project’s library/build environment might somehow be corrupt, I created a new PlatformIO project and pasted the code into new files there, still no luck. I’ll attach two…[Read more]

Global update did it – thanks!

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]

Hmm… still having errors with the TINY_GSM_DEBUG macro after updating libraries. Here’s the pio lib update’s output:

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

Yeah sorry about that will try to answer better. Im really appreciative about your help!

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

Yes you are right. Ive ne…[Read more]

Haha… If your metric is Amazon reviews, well….      🙂

The doc effort definitely shows. I first came to a Stroud workshop in ~12/2017; then we (TU) jumped in deep with the Mayfly, so I picked it up again last summer or fall, and wow! what an advance in documentation! And y’all even incorporate user input – quickly!

One day, hopefully so…[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!

Great, thanks, we’ll try the library update and see if we can get some useful traces. We’re using transparent.

Reading docs is on my to-do list. =:D  Good documentation is definitely hard! Actually, the Mayfly manual is impressively good, as are the docs in ModularSensors github repo.

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]

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]

One additional detail: after it failed to build, I commented out –DTINY_GSM_DEBUG=Serial, and it built, but of course, got no debugging info in Serial Monitor.

@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]

• Are you using breadboards or have you made a custom circuit of some kind? Post a picture.

Yes i put it in.

• By what is the Yosemitch sensor powered and at what voltage?

Connected in a levelshifter from a arduino mini pro.

• Exactly what RS485 to TTL adapter do you have connected between the A and B (green and white) of your Y500B and you…
