Hi Nathan & Sara,

I have just purchased an ISCO 6700 auto-sampler to collect some storm flow samples in my region, with the intention of using the data to supplement load calculations.  I would like to set this up so that it will trigger when a measured variable crosses a pre-defined threshold.  I would also like to be able to trigger remotely b…[Read more]

@dartmouthwsn Thanks for the offer, Dave! We’re definitely interested and would really appreciate it if you would share information in a blog post here on EnviroDIY. Please email me at webmaster@stroudcenter.org for details.

Looking at this posts as a discussion on general SDI-12, I have the Mayfly interface working for a Insitu LT500 Water Level monitor in a prototype capacity.

The LT500 requires an 8-36V Excitation, so I put in a series booster,  +12V   https://www.pololu.com/product/2117, and connected the other end to Grove 4pin JST-PH cable (std one cut in h…[Read more]

Hi everyone,

Some updates on this project – we now have 12 loggers monitoring 8 sensors at each site. It took a full field season but now have all the wiring free of shorts and power problems. We have mostly been focused on the data collection side and, because of COVID, don’t have resources to work solely on the 900Mhz radio network element…[Read more]

Wow! That is amazing – and very helpful! I thought it may be an issue with a line in the library – we migrated to Meter group sensors which seemed to work – perhaps because of their ability to wake up more quickly.

Thanks for the update Shannon – we have 12 out in the field for collecting soil moisture in a project with the USFS – I should probably update that thread. We are looking to buy 15 more for installation in Vermont now, too.

One cool piece of info for you all is that the Mayflys we had installed over-winter in northern NH made it through -20F…[Read more]

Folks

OK, I have data coming in, and can print to serial to see the output on serial monitor. Now I’m having a lot of difficulty declaring the new variables in my sketch in order to log the data using the LoggerBase, and I think it might be how the author of the GPS C++ code that I’m using set up the structures and classes in the header file. I…[Read more]

As stated above, I’m prepping the products right now for shipment to Amazon, so they should be available whenever Amazon receives them, processes them, and lists them as available on their system again. I have no idea how long their side of things will take, sometimes it’s only a few days, but lately it’s been more like a week or more. Amazon is…[Read more]

Thanks heaps (as we say in NZ) everyone! James is working with us, but is an hour+ drive away. We didn’t test his LTEbee and adapter before handing it to him, so it seems like the best way to troubleshoot will be to get the pieces back where we have 3 sets (and one that was definitely working when we bought three more).

I could be needing about 6 Mayfly’s + 1 LTE Adapter Board – where is the best way of placing an order, many thanks Neil

There’s also the possibility that the LTEbee adapter board is broken or dead. We’ve had a few rare instances of them not working due to a manufacturing defect on the first batch of boards. So if you’ve got another LTEbee adapter you could swap out, or get a carrier board for the Xbee LTE module, you can determine which is the dead part.

Hi Sara,

Alas, no light.  I think that explains why I haven’t had any luck! And why the guys at the university passed it on to me to see if I could get it to work.

Thanks for your help.

James

Ok, so for testing the XBee with what you have:

• check for any blobs of solder on the solder jumpers or any modifications made to either your Mayfly or LTE adapter – let me know if there are any
• check and re-check to make sure the pins in your bee stack are all aligned and in the right holes, ie, they’re not all shifted up or down 1 spot

To modify the Mayfly to work as a carrier board you’d need to cut and re-solder jumpers SJ8 and SJ9 on the back of the Mayfly to connect Bee Tx and Rx to Tx 0 and Tx 1.  You would want to undo the change to use the Mayfly again normally.  I’ve never actually tried this modification and am not 100% positive it would work.

I suggest you just f…[Read more]

Ok, so you have a stack with a Mayfly, an LTE adapter board, and a XBee3 (3 parts).

You don’t have a separate development or carrier board.  All of my comments about the USB-C/USB 3 apply only to a separate carrier board.  If you don’t have one, don’t worry about that.

Hi Sara & Shannon,

Thank you for your quick reply.  Answers to/comments on your questions are as follows:

• How are you attaching your XBee to the computer?   – I am attaching the XBee to the Mayfly via a LTE module.
• Are you plugged into the USB-C port, not the side microUSB?  – I am plugged into the microUSB on the mayfly.  This is plugg…

Are you using one of our LTEbee adapters between the Digi Xbee LTE module and the Mayfly board? https://github.com/EnviroDIY/LTEbee-Adapter
