If you are worried about paying for cellular service you might look into Twilio. They have a SuperSim that we used in our XBee-NB/IOT units that will connect to 4 carriers. It costs $2 month for the card and they only charge you for usage. We were running MQTT w/TLS with small messages for temp every 5 and precip every 15 with other hourly…[Read more]
Rick Vogel replied to the topic Using the Teensy 3.5 in the forum Other Data Loggers 2 years, 9 months ago

@neilh20 Yes, the chip supply pretty much put a spike in the Teensy 3.5 for any type of continued development and usage with that chipset. We used the 3.5 because of it’s 5V tolerant I/O. The Teensy 4.1 did not have that so the project stalled for a bit. I believe the folks who have taken that project over are considering moving the XBee to a…[Read more]

@vogelrnws I wonder how its going. I see that Teensy is moving to a Teensy4.0 CortexM7

Great, thanks @srgdamiano! Got it working on my desktop; now will deploy into the field.

One small change: The lib_deps line I used to grab the latest ModularSensors was:
```
envirodiy/EnviroDIY_ModularSensors
```
(without a version number).
Sara Damiano replied to the topic LTEBee conflict with NeoSWSerial? in the forum Mayfly Data Logger 2 years, 9 months ago

I’m sorry; I’m stumped. There’s something wrong with the way the battery voltage is being read. But I don’t understand what. As soon as I turn on the debugging for it.. it works. It also works if I upgrade to the current ModularSensors master branch. But I cannot figure out for the life of me what change makes it work.

So my two suggestions to…[Read more]
Sara Damiano replied to the topic LTEBee conflict with NeoSWSerial? in the forum Mayfly Data Logger 2 years, 9 months ago

I’m looking into it. I would have said “of course they should work together” but I’d never tried it, so I hooked it up and tried it out. And I got the same result as you. I haven’t figured it out yet, though.
Matt Barney started the topic LTEBee conflict with NeoSWSerial? in the forum Mayfly Data Logger 2 years, 9 months ago

We have an EnviroDIY station that’s been running for a number of months, using a v0.5 Mayfly with Digi LTE modem, a CTD, and a Maxbotix sonar sensor. More recently, the Digi failed, and we upgraded the modem to an LTEBee and the Mayfly to a v1.1. Accordingly, I updated the code (attached) for the new modem. Since then, no data has been uploaded to…[Read more]
Shannon Hicks replied to the topic Mayfly v1.1 technical questions forum thread in the forum Mayfly Data Logger 2 years, 10 months ago

It depends on what you mean by communicate. Are you wanting to transmit data wirelessly between a Mayfly and another Arduino-compatible device? Or are you meaning a direct cable connection between the two devices? Either way is possible, but it really depends on a lot of factors, like what sort of data are you transferring, how often, and wh…[Read more]
rachaelchertok replied to the topic Mayfly v1.1 technical questions forum thread in the forum Mayfly Data Logger 2 years, 10 months ago

Hello! I was wondering if the Mayfly has the ability to communicate with other Arduinos, preferably the Nano?

Thank you in advance!

Shannon Hicks replied to the topic 12 V External Power and Serial Viewer in the forum Infrastructure and Equipment 2 years, 10 months ago

If you’re using an external FTDI or CP2102 interface board to program your Mayfly via the Mayfly’s FTDI socket, then the Mayfly dipswitch labeled USB should be turned off before connecting the external interface to the Mayfly, and it should stay off the entire time.

What version of the Arduino IDE are you using? From your screenshot, it looks…[Read more]
Apryl replied to the topic 12 V External Power and Serial Viewer in the forum Infrastructure and Equipment 2 years, 10 months ago

So, if I understand correctly, I should be able to use the USBC to Serial (CP2102N Friend, oriented properly) via the FTDI port to upload sketches as well as access the serial monitor with the 12V to 5V DC converter plugged into the Mayfly’s USBC port (for the sensors that require 12V), but the DIP switch for the USBC on board chip needs to be…[Read more]

Thanks so much, Neil, for taking the time to write this. I’m sure it will be helpful to a lot of folks!

The Mayfly 1.1 is great for powering options – but it does mean understanding the tradeoffs.

For an FTDI cable, for debug monitoring of the Mayfly this is what I do – https://github.com/neilh10/ModularSensors/wiki/Test-Equipment-FTDI-cable

I also cut some pins to make it a “monitoring cable” that won’t cause a reset when the USB is plugged in.…[Read more]
Shannon Hicks replied to the topic 12 V External Power and Serial Viewer in the forum Infrastructure and Equipment 2 years, 10 months ago

You are correct, if you’re using the USB jack to power a v1.0 or v1.1 Mayfly using a 12v source, then there’s no way to interface the Mayfly with a PC for programming or viewing serial output. However, all Mayfly boards include an FTDI jack that allows you to connect a variety of FTDI cables or adapters in order to communicate with the board in…[Read more]
Apryl started the topic 12 V External Power and Serial Viewer in the forum Infrastructure and Equipment 2 years, 10 months ago

I feel like there should be a simple solution to this, but I haven’t stumbled upon it yet. The 1.1 version of the Mayfly board now needs a DC converter connected to the USB C port in order to have 12V external power. When connected this way, everything seems to work. However, I can no longer access the terminal viewer while the converter is co…[Read more]

Shannon Hicks replied to the topic 2022 EnviroDIY Hardware Status and Availability in the forum Mayfly Data Logger 2 years, 10 months ago

It’s still in the prototype and testing phase, but the good news is the the chips that were unavailable for the past 18 months are finally available again. If you or anyone else have specific RS485 sensors that you’re hoping to use, it would be helpful if you email me at mayfly@envirodiy.org with your sensor model information so we can make sure…[Read more]
