How and when did you download all of your libraries?

Are you using anything else from the Modular Sensors library? Post your entire sketch as code (use the <> button to post as code)?  Are you setting the host and port for the mqttClient? (mqttClient.setServer(ip, port)) Use your local IP there.  If you do that, I don’t see why you’re not getting a connection even with the bad DL setting in the e…[Read more]

Ooooh.. yup, there’s a bug in DigiXBeeWifi.cpp.  I’ll look into it.

Exactly which version of the library are you using (release, master branch, develop branch)?

For now, you may be able to get it working by commenting out lines ~303-310 in src/modems/DigiXBeeWifi.cpp, the section starting with “set the destination IP to 0”

If that doesn’t compile for you, update your TinyGSM library or just delete lines 87-92 to remove the forceModemBaud command, which needs the version of TinyGSM within the last few weeks.

It it’s working for you, comment out the section that resets the modem to defaults (lines 107-126) and run it one more time to get the modem to 9600. It should…[Read more]

Use 3.3V to power the WiFi bee and make sure that you’re adapter uses 3.3V logic.  The 0.5A most USB ports can provide should be enough for the WiFi bee without browning out.  You are seeing the lights on the bee go on, right?

This script worked for me to force the baud rate on three different WiFi Bee’s.  The script forces the baud rate and th…[Read more]

Once you’ve successfully changed the WiFi bee’s baud rate, it will stay at the slower baud. You should only have to reset the baud rate if you factory reset the bee or update it’s firmware – neither of which you can do by accident.

The WiFi bee should have the AT firmware on it. The problem probably is the baud rate. The default baud rate for the ESP32 (the brain on the WiFi bee) is 115200. That’s too fast for stable communication with the 8MHz Mayfly.  The Mayfly can usually *talk* fairly accurately at 115200, but it can’t listen that fast.  The auto-baud function depends o…[Read more]

Using ModularSensors doesn’t necessarily require the sensors to be directly connected to the Mayfly.  They could be, but they don’t have to be. In the case of a lot of inexpensive sensors sold as breakout boards, the Mayfly connects and talks directly to the sensor, but most of the not-bare-circuit sensors have black-box layers between the raw…[Read more]

I spent some time skimming your GitHub code for your device.  If your logger is using a simple serial protocol to communicate with your GUI controller, it should also be able to communicate with the Mayfly (with or without Modular Sensors) in the same way if you expose the Serial (or AltSoftSerial) pins.

ModularSensors already supports the MS5803…[Read more]

We don’t have any set requirements for connection.  The Mayfly can communicate with almost anything that could communicate with an Arduino-style device.  Many users opt to user our ModularSensors library to run their loggers, but that library supports many protocols.

SDI-12 devices are very common in the environmental sensing field, so we have a…[Read more]

If you’re only running the sketches from Modular Sensors, you should delete all of your libraries and download the bundle from the ModularSensors release page: https://github.com/EnviroDIY/ModularSensors/releases/tag/v0.37.0 (Direct download link:…[Read more]

How is the sensor connected? To disconnect a grove plug, squeeze the lock at the top of the white connector and pull it off.  This is the headphone (stereo) jack: https://www.envirodiy.org/product/envirodiy-grove-to-3-5mm-stereo-jack-pack-of-2/. The stereo/headphone connector is just like the one on wired headphones.

If you’re getting a “could not wake modem” error it means there’s something wrong with the modem power or connection between the modem and your main board.  Are your modem lights turning on? There should be a solid red light and a flashing blue light? Make sure your board is in the socket correctly with the cut corners at the top and all the pins…[Read more]

Does the red power light on the lower right of the modem turn on? If not, the modem isn’t getting power. Pin 18 should be the right pin number. I’m not sure why it wouldn’t be powering up. Have you ever messed with the solder jumpers?

If the modem is powering up, you might have a baud rate problem. Try setting the modemBaud to 57600 even…[Read more]

According to the product change notification you attached, there shouldn’t need to be any software changes for “transparent” mode, so most of the examples for ModularSensors should still work.

The underlying cellular chipset on the board *has* changed from the ublox SARA R410M to the Telit ME310G1-WW on the global version or the Telit ME310G1-W1…[Read more]

I’ve been swamped lately, so I’m behind on sensor requests.
<div>
<div>@fionasouthwell Are you sure you’re measuring *specific conductance*? From what I know of the Atlas sensors, they don’t measure specific conductance, they measure conductivity. I just very quickly skimmed their latest manual and it doesn’t look like that’s changed. To get…[Read more]

You need to either upgrade your ModularSensors library from 0.34.0 to 0.35.0 or downgrade your SD fat library from 2.2.3 to 2.1.2.

All the dependent libraries are updated all of the time and not all versions match with each other. It’s best to download the libraries as a package from the ModularSensors releases page on GitHub. That zip file…[Read more]

I know nothing about rosserial. Are you using Hardware Serial with it? Serial or Serial1? Are you using some type of software serial (SoftwareSerial, AltSoftSerial, NeoSWSerial)? Very quickly skimming the rosserial docs and code, it looks like it has some specific boards that are supported and the 1284p in the Mayfly may not be 100%…[Read more]

This code still works for me. Are you sure you have your start and end dates set within the range that your sensor has data?

The list Shannon shared for ModularSensors should be up-to-date.  But the Mayfly itself can interface with many, many more sensors that are supported by libraries other than ModularSensors. We couldn’t make a comprehensive list – almost any sensor that can work in an Arduino environment can be used with the Mayfly.
