From Dave Funk, entomologist at the Stroud Center (https://stroudcenter.org/people/funk/):  “I’d be very surprised if there were any among the EPT’s–no structures I am aware of that might suggest either a source or sensor. It seems to me the most likely place to find sound communication in aquatic insects would be among (non-benthic) adult…[Read more]

The LTEbee adapter board you linked above was a special product we developed in 2019 for interfacing the Digi-brand LTE cellular boards with the Mayfly Logger.   The Digi board have been nearly impossible to buy since late 2020 because of production/shortage issues with the manufacturer and aren’t expected to be back in stock anywhere until l…[Read more]

I have the serial number 20347 purchased in 2020. (v1.0)

would the LTE Bee work with v1.0? EnviroDIY LTE Bee (Pack of 5)

I’ll second Neil, and say that Keller sensor are very high quality and work really well with Mayfly RS485 integrations. I’ve helped deploy many AccuLevel sensors.

There’s a small chance that Keller 36XiW-CTD uses the same Modbus map as the Acculevel, but I think it is unlikely. You’ll need to get the Modbus documentation from Keller for that. I…[Read more]

@shicks

I emailed the sketch and the associate pio .ini file.

Thanks for looking into this.

Email me your sketch and I’ll load it to a v0. 5b board and see if I can recreate your issue.

I assume that the NeoSWSerial function is needed. to talk to the sim7080 and that is why I am not getting any response from the modem

The new sim7080 is plugged directly into the Mayfly 0.5b.

Are you using the new sim7080 directly plugged in to the Mayfly, or are you still using the LTEbee adapter board from your old Digi hardware in between the sim7080 and the Mayfly?

@srgdamiano @hicks

Current status of my problem; I am using the 0.5 Mayfly board and have changed to appropite line from 18 to -1 and I get compile errors related to NeosWSerial.ccp.  I have updated all my libraries and still get the same error.

If I comment out the lib entry for NeoSWSerial the sketch compiles but when loaded the console…[Read more]

We haven’t used that sensor at Stroud, but after looking at the spec sheet, I don’t see why it wouldn’t work with one of our newer Mayfly models that generates 12v.  You’ll need a Modbus interface if you want to use that protocol, so either building your own or using the one we’ll be releasing soon.  For SDI-12, it should work directly connected t…[Read more]

@zeke-holloman communications – peer2peer – is a deep subject.

Many years ago I wrote the code for a comms stack to use the 9bit UART to poll an array of processors. In the end it was 2people for 18months to get it working reliably.  So its not trivial, but i had a fantastic time with…[Read more]

The Mayfly board is not a I2C slave device so it does not have an I2C address.  The easiest way to transfer data between Mayfly boards would be to use UART like serial or NewSoftSerial.
