The LTE Bee (and WiFi) can change IP addresses at any time.

Great! Thanks for the quick reply.
One followup question: I think I saw a reference in some of the documentation about the LTE module having restricted source and destination IP addresses i.e. once configured it will only work with a single destination address. Is that correct? And if so, does the WiFi Bee have a similar restriction? (Or maybe…[Read more]

The WiFi bee is actively being supported. It’s what I test with on my desk. Switching back and forth between WiFi and LTE is fairly simple. But you should still do some LTE testing on your desk before moving to the field.
If you’re using a Mayfly, I’d go with the WiFi Bee. It plugs right in. Any other shield would require jumper wires or other…[Read more]

I may be helping a friend with some software development on a Mayfly logger. He uses an LTE Bee module in the field when his loggers are deployed, but I don’t anticipate being in the field myself. Communications in the field require IP service. Instead of using an LTE Bee module while I’m developing, I’m considering an EnviroDIY WiFi Bee module or…[Read more]

Thank you!

Sara Damiano replied to the topic Sampling Feature UUID for manual data upload in the forum Mayfly Data Logger 1 week, 2 days ago
You need to set the sampling feature UUID for the logger. If you have an EnviroDIYPublisher, this happens automatically, but without the publisher, you need to add it.
So after you set the logger pins in line 283 (
dataLogger.setLoggerPins()
), add the linedataLogger.setSamplingFeatureUUID(samplingFeature);

I have a colleague for whom I programmed a Mayfly without any modem-related code because this station has no cellular service nor modem, so they upload data to MMW manually from the SD card. However, the data file being written to the card does not contain the Sampling Feature UUID, so they have to add that to the data file manually before it can…[Read more]

Many thanks got it. I appreciate the effort and detail that goes into producing a new production run. The pogo pin connector is great and so simple.
Got the .pdf – I copied the .jpg instead of more intelligently clicking it to get the .pdf!
Just wondering if you have any thoughts on changing the Vbat Rs to 1M / 270K for better noise i…[Read more]

The only differences between the v1.1 revA and revB are this:
The ICSP jack was a 2×3, 0.5″ pitch male pin header on Mayfly v1.1 revA.
The ICSP jack is now uses Tag-Connect pads for use with Pogo pins for ICSP programming for the Mayfly v1.1 revB.And with the revA boards, there was a circuit design change after manufacturing that required me to…[Read more]

Shannon Hicks replied to the topic How to determine battery and power supply in the forum Mayfly Data Logger 2 weeks, 6 days ago
If you’ve got 4 heated sensors that require constant 12 volts, then I don’t think the Mayfly and the standard “battery/solar panel combo” is going to be sufficient. It would be a struggle for the Mayfly to supply the necessary continuous 100ma at 12v for the heaters, in addition to powering the various sensors intermittently. You could have a s…[Read more]

Hi @shicks, just received two Mayfly 1.1 and noticed they are rev1.1B – just wondering what the differences are from rev1.1A? 🙂
I did pull the circuit diagram from https://www.envirodiy.org/mayfly/hardware/ however the resolution is so low, its not all readable. Just wondering if there is a pdf version. 🙂
I also checked…[Read more]

I’ve attached the specs sheet to this reply. Maybe you can help me interpret it. The following is what I was told from Apogee when I asked about the heaters:
“Regarding the <span class=”markjqg79ytz9″ data-markjs=”true” data-ogac=”” data-ogab=”” data-ogsc=”black” data-ogsb=”rgb(255, 241, 0)”>heater</span>s, you do not need to operate them all the…[Read more]

Sensors with heaters are another big challenge, especially if they run continuously. Are the heaters powered all the time, or only when taking a sample? Do they require 12v to operate, or was that spec just listing the power draw at 12v?
