Matt Barney replied to the topic LTEBee on Verizon? in the forum Mayfly Data Logger 2 years, 3 months ago
The SIMCom 7080G modem chip upon which the EnviroDIY LTE Bee is built did not have Verizon certification until early August. Once they notified me, I asked SIMCom support what APN setting to use for Verizon, and this was their response:
Set you APN as…

OK, got it, thanks.
I’ve made the hardware and software modifications you recommended and all seems to work perfectly.
Thanks again.

Matt Barney replied to the topic Digi LTEBee on Mayfly v1.x in the forum Mayfly Data Logger 2 years, 4 months ago
Thanks for this excellent detail.
So we could continue to use the LTEBee adapter with the Digi modem on a v1.1 Mayfly, which would retain the functionality of the white and blue modem status LEDs, and would connect the Bee socket’s pin to the proper status pin on the Digi (without need to modify SJ19), and we would not need the power jumper to…[Read more]

Matt Barney started the topic Digi LTEBee on Mayfly v1.x in the forum Mayfly Data Logger 2 years, 4 months ago
What jumper settings are required to operate a Digi XBee LTE-M on Mayfly v1.x? I’ve read the jumper settings page, which details what each jumper does, including the Bee socket-related ones, but without being familiar with the electrical requirements of the Digi, I’m unclear what needs to change. I have a likely-failed Mayfly v0.5b, which I’d like…[Read more]

Matt Barney replied to the topic Code change for Meter Hydros 21 CTD in the forum Mayfly Data Logger 2 years, 5 months ago
A couple bits of additional info. To visually identify whether your Hydros 21 is a Gen 1 or a Gen 2, see attached photos of the sensor head on each version. Note that some Gen 1’s had red cables, but not all.
Second, as Shannon noted in the post she linked to above, the address-setting on the Gen 2 is slightly more finicky; you just have to…[Read more]

Matt Barney started the topic Code change for Meter Hydros 21 CTD in the forum Mayfly Data Logger 2 years, 5 months ago
I don’t recall seeing any announcement on the forums, so I thought I’d share with everyone that the latest Hydros 21 sensors (Generation 2) require ModularSensors version 0.33.3 or later. We recently learned this after replacing a failed sensor in the field, and our Mayfly could no longer communicate with it. Since we have dozens of EnviroDIY…[Read more]

Matt Barney started the topic Error setting Hydros21 address in the forum Environmental Sensors 2 years, 5 months ago
I’m getting the error “Not a valid address” when using the b_address_change.ino sketch in Arduino IDE. However, the address does appear to be getting set as expected, and I can change it to 2 and back to 1; it outputs the error each time, so it just looks a little odd. I’ll attach the output from the serial monitor below.
This is with a new Gen 2…[Read more]

Matt Barney replied to the topic Hydros 21/Decagon CTD: reading error in the forum Environmental Sensors 2 years, 5 months ago
We’ve just had a failure to communicate with our newest Hydros 21 sensors (likely Gen 2). While I’ve had success setting the address with the b_address_change sketch, my standard Mayfly code can’t talk to the sensor and returns values of -9999. It looks to me like the SDI-12 library has not changed since May 2021…[Read more]

Matt Barney started the topic Abnormally high battery voltage in the forum Mayfly Data Logger 2 years, 7 months ago
We have 2 stations we’ve recently deployed which are reporting ~7.5 volts during the day and 4.2V at night (graphs attached).
I suspect that the solar cable was accidentally plugged into one of the LIPO BATT ports (with the battery is plugged into the other LIPO BATT port). They’ll get that corrected asap, but I want to ask @shicks: Would this…[Read more]

We are also seeing the missing display of “Last observation” values for all new stations we deploy, though it continues to work for stations that were deployed prior to the MonitorMyWatershed release on December 7th.

I’m also unable to delete sites (Server Error 500), and unable to delete sensors (no errors, but nothing gets deleted). I am going to report this via an issue at the Github site for the MMW data portal:

Matt Barney replied to the topic Voltage divider on multipurpose screw adapter in the forum Mayfly Data Logger 2 years, 10 months ago
Thanks for the schematic – that is helpful. I removed the solder blob using solder wick and re-added it to the res-div position, but it wasn’t pretty; it looks like I overheated the board a bit, but it still works. Later, I found a different technique in this video, which I’ll share here for anyone else who needs it.

FYI, Turner tech support tells me that Signal Ground and Supply Ground must be “Kept separate so that noise isn’t injected into the response.”

Matt Barney replied to the topic Voltage divider on multipurpose screw adapter in the forum Mayfly Data Logger 2 years, 10 months ago
Thanks Shannon. I’m not positive that I need to use differential measurement… I’m approaching the edge of my knowledge as a non-EE. Turner doesn’t specify whether it’s OK to connect signal and power grounds to the same point — maybe I’ll ask their tech support. But when the sensor is on, I’m measuring around 13 mV between its signal ground and…[Read more]

Matt Barney replied to the topic Voltage divider on multipurpose screw adapter in the forum Mayfly Data Logger 2 years, 10 months ago
After probing the screw term adapter, I don’t think that it will work for my purposes as I described above. If I’m correct, the way the adapter’s voltage divider works is this: When the S1 jumper is set to Res-Div and two matched resistors are installed on the S1 side of the adapter, the voltage output on the Grove’s D1 pin will be half of the…[Read more]

Matt Barney started the topic Compiling for Mayfly v0.5 or v1.0 in the forum Mayfly Data Logger 2 years, 11 months ago
I have a question for @neilh20, regarding this post:
I’m making ModularSensors detect in runtime whether its Mayfly 0.5 or 1.0 – so the user/program doesn’t have to compile for one or the other.
I’m curious why you found that necessary. I’m generally using the same code on both boards, unless they’re using different versions of cell modems.
Thanks!
