Wow nice to see the pictures and mechanical detail. I always find that a challenge to get integrated early – mostly because I’m doing everthing. Is it part of an open source project? sounds like its for a specific translator/extender fiber optics to copper RS485/RS23 In looking over the Rpi PICO, while an amazing processor with program st…[Read more]

I’ve ported MS to the Wio Terminal – which has an ARM “CORTEX-M4” SAMD51 microprocessor
It opens up a whole field of potential Adafruit boards that also use versions of the SAMD51 https://www.adafruit.com/search?q=SAMD51 The big benefit of the SAMD51 is that it can got to a 2Mbytes of Flash and possibility even larger with XIP “execute in…[Read more]

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]

@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:
(without a version number).
Sara Damiano replied to the topic LTEBee conflict with NeoSWSerial? in the forum Mayfly Data Logger 1 years, 2 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]

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.

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 1 years, 2 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]
