It’s not really an error, it’s just an artifact of the Eagle Cad schematic component since the original part in my library was for the ADS1015/1115, since both parts share the same footprint and schematic shape, but there’s no way to easily change the name displayed without editing the device.  I had to manually update that on previous Mayfly…[Read more]

There is no benefit in turning off the USB dipswitch if your board will be deployed with only a Lipo for power.  The switch is there solely for the purpose of deactivating the USB interface chip in case you are powering the Mayfly via the USB jack and want to save power, because the CP2102 chip can draw up to 10ma when idle, so turning it off can…[Read more]

I’ve never experienced this problem with any of the Mayfly boards on any of the various PCs I’ve used them on, but I do have a colleague who has a similar problem with another CP2102-based board.  I think his solution was that sometimes it takes plugging and unplugging the device a few times before Windows finally recognizes it and assigns a com…[Read more]

Sara is the person who wrote that PCSync program, so she’ll have to be the one to comment on why it’s not working.  I’m assuming it’s just looking for the FT232RL device of the older Mayfly boards and isn’t programmed to see the CP2102 of the Mayfly 1.0 as a viable device.  In the meantime, you can just use the the DS3231/adjust.ino sketch to m…[Read more]

I added a sketch called “DRWI_sim7080LTE.ino” to our Github repository.  You can find it here https://github.com/EnviroDIY/ModularSensors/tree/master/examples/DRWI_sim7080LTE along with a brief summary.

We’re still working out the bugs in the libraries that was cause by an update to an external library that is included in our bundled files (the…[Read more]

I’ve been trying to resolve an issue with a sensor library file that is currently causing an error when users compile any sketches using ModularSensors.  Sara and I worked on it this afternoon and will hopefully have it resolved soon.  In the meantime, I’m working on an instructional page for the sim7080 module as well as posting example s…[Read more]

The Mayfly v1.0 boards use a new USB interface chip called the CP2102 instead of the old FT232RL that was found on earlier Mayfly boards.  When you first connect it to your computer, your operating system should recognize it and install the necessary drivers.  I connected each new Mayfly to 3 different computers (2 PCs and one Mac) before s…[Read more]

The same Hologram SIM cards we’ve been using for the past year in the Digi boards work just fine in the new EnviroDIY LTE boards.

The new EnviroDIY LTE bee works in the old Mayfly 0.5b boards, and no LTEbee adapter is needed.  The LTEbee adapter is only needed when using Digi boards with Mayfly 0.5b boards.

Digi LTE CAT M1 boards work directly…[Read more]

As stated in the blog post about the new releases, I’m working as fast as I can to prepare all the products for shipment, and will be updating the shop and forum as soon as they are available.  The Monitoring Station Kit will take a little bit more time to be released because we’ll be changing the contents of the kit slightly.  In the meantime, I…[Read more]

I haven’t had any issues with any loggers not recording data recently or clocks not running, including boards I just programmed this week.  But I use stable libraries from several months ago and haven’t updated them recently.  Are you using all the libraries that are available in our suggested .zip file, found here: h…[Read more]

The we’ve found that loggers with the Digi cell boards on them have a tendency to act a little squirrely sometimes and give either erroneous readings or cause excessive power draw.  In you case, I’d start with putting a fully-charged 4400 mAh battery on your station and see how it performs for a few weeks.  If that doesn’t solve it, investigate t…[Read more]

The website reports on the last time data was received by the website via the cell modem.  So you’ll have data on the card that’s not on the website.  And there are 2 date/time columns in that data file, one is local time (standard) and one is UTC time.  They are 5 hours off if you’re in the eastern time zone.  So data points in the evening bef…[Read more]

Your battery is too low.  This is the same issue that was asked about last week:  https://www.envirodiy.org/topic/battery-failing-in-the-middle-of-the-night/

Anytime your battery voltage drops below 3.55v, the logger won’t transmit, in order to save battery power and conserve enough energy to keep writing the data to the memory card even though i…[Read more]

The data looks to me like the battery voltage dropped in July, someone replaced it with a charged battery on 8/4 and data was continuous, but then on 8/25 someone replaced the battery with the almost-dead one from earlier in the month.  And if you’re using the sample LTE logging sketch like what’s found here:…[Read more]

The shipment of new boards and accessories arrived 3 weeks ago.  I began testing the products and making the necessary changes to the code and documentation, but then our area was hit by the remnants of Hurricane Ida, several dozen of our stream monitoring stations were located on rivers that saw flood events greater than anything that’s happened…[Read more]

Sounds like it’s working, that’s a standard response string for that sensor.  Is there a particular reason you’re requesting the Mega to print the result in hex instead of decimal.
