There are some bugs with WOFpy right now; I think some had been fixed, but I don’t remember the current state. I know that even when it is working large data queries tend to crash browsers.

Just a note on sending to ThingSpeak: there’s no free tier for anything but “personal use.” If you set your MathWorks/MatLab/ThingSpeak account up as anything else (even non-profit/educational) you only get 30 days free and have to pay beyond that, no matter how low your usage is.

If a new csv is being created, it’s almost certainly because the logger is restarting. It could be some irregularity in the power that’s causing the board to restart directly or it’s the watchdog. If you’re not specifically setting the file name, whenever the board attempts to talk to the SD card, it puts together the logger ID and the date and…[Read more]

Right now there’s no ability to do units conversions in either ModularSensors or on Monitor My Watershed. Your only option in ModularSensors would be to create a calculated variable that did the units conversion.

On Monitor My Watershed, I think almost all of the temperature variables have the option of being in either C or F, but nearly…[Read more]

To turn on the “deep” debugging for the modem, add build flags “-DMS_DIGIXBEECELLULARTRANSPARENT_DEBUG” and “-DMS_DIGIXBEECELLULARTRANSPARENT_DEBUG_DEEP” for cellular or “-DMS_DIGIXBEEWIFI_DEBUG” and “-DMS_DIGIXBEEWIFI_DEBUG_DEEP”. Keep the publisher build flags set. You’d also have to change your serial monitor line endings to just a carriage…[Read more]

The only thing coming to mind right now is possible issues with the json or the content length header. If the length of the json doesn’t match up with the actual size of the json, the send would probably be rejected. (You’d get a 5xx I think.) Unfortunately the only way you’d see that 5xx or details on why the send failed would be to turn on…[Read more]

I’d completely forgotten about the filename issue, too. It’s definitely a “gotcha” that’s hard to catch.

Hm. Well, I’m stumped. I have issues all the time with the cellular, but not the Wifi.

I’m sorry; I’m going to throw a zillion questions at you again.

You’re using 4 separate Mayfly’s, right? (ie, you don’t have both the wifi and cellular XBee’s hooked up to the same Mayfly). You’re wifi is connected to “real” wifi, right? (ie, not a…[Read more]

In asking about “your other thread” I meant this: https://www.envirodiy.org/topic/sd-card-recording-data-issue/

You need to make the modifications I mentioned above. You also need to pick a file name that is less than 8 characters, ie, “cond.txt” instead of conductivity.txt. I’d forgotten about the filename issue.

Your new code would be:…[Read more]

Did you get a chance to do any more troubleshooting on this?

It sounds like what you’re really after is a good LIMS system to help your technicians ties measurements to the correct sites and then visualize them all together on a map. The MontitorMW portal can only really help with the visualization part.

Yay! That’s more like it.

There are several posts and GitHub issues comparing the two but here’s a quick summary:

Bypass:
+ connects to the network faster
+ near 100% success in sending data if a network connection is made
– every transmission uses very slightly more data (in uncontrollable overhead – unsure why)
– Digi strongly discourages use…[Read more]

Select “All” as the manufacturer and “Calculated” as the sensor model.

Oops. So, it never tried for longer than 15 minutes with that sketch because the watchdog doesn’t get “fed” while it’s waiting for the internet and it “bites” (ie, forces the board to reset) after 15 minutes. But 15 minutes is still a pretty long time to wait.

After the first connection in a new location, it should connect much faster in…[Read more]

Hm. I’m not quite sure I follow you.

It sounds like you have a sensor package that you deploy at one spot for a while, then you stop it, pack it up, and move it somewhere else. After some time, you move the sensor package back to the original site. Is there ever data being collected while it’s moving, or is the GPS data only being collected to…[Read more]

I think

File Conductivity1 = SD.open(“Conductivity.txt”,FILE_WRITE);

should be

Conductivity1 = SD.open(“Conductivity.txt”,FILE_WRITE);

You also should have a

Conductivity1.close()

before the last delay.

Are you using a Mayfly? Are you using the built-in microSD card slot or the vertical adapter? What output do you get?

Did you ever ge…[Read more]

@ensign – yup, it’s a nice video. But… creating a video like that automatically for every set of uploaded trajectory data is just a little bit more difficult than making a simple plot with time on the x axis.

The WinRiverII software for the moving acoustic Doppler current profilers that we use to take discharge measurements has some nice…[Read more]

Hm. You have the LiPo plugged in in addition to the USB, right?

Are you sure you have service and the antenna is well connected? Don’t yank the antenna off unless you really have to; those u.Fl connectors are fragile and after 3 or 4 times of being disconnected and reconnected they stop working.

Have you ever gotten your XBee3 to connect?…[Read more]

Scott Ensign, formerly of Planktos Instruments, is now at Stroud. (He’s @ensign.)

I don’t know how “unusual” trajectory data is, but, at least in long term stream monitoring, it’s definitely far less common than fixed station monitoring. That type of data is also harder to manage, visualize, or conceptualize. I’d guess if others don’t support…[Read more]
