Khaase started the topic Mayfly 1.1 Bootloader Burning? in the forum Mayfly Data Logger 1 years, 11 months ago
I haven’t seen a discussion about burning a bootloader to the Mayfly 1v1. I presume the best way to so go through J7 with my ISP.
Is there any special guidance? How is this done during assembly?
The reason I am messing with the bootloader is that I’m trying to get Mayflys to live off some big batteries for a project in a cold dark place for a…[Read more]

Adolfo Lopez started the topic PlatformIO Developer Setup in the forum Mayfly Data Logger 1 years, 11 months ago
Hello all,
I’ve been trying to properly set up my platformio.ini configuration file to test some code out, but keep running into issues. I tried following the steps from the ModularSensors page but haven’t had any luck. Would someone be able to walk me through this process?

Dear Shannon , I have already connected the GND of the Modem and GND of the Mayfly. Interfacing between Mega2560 to the Modem I have used of level converter ( 3.3V to 5 V) for TX1 and RX1 . Because the operating of the modem is 3.3 Volt and the the Mega is a 5 Volt.
The operating of the Modem was a 3.3 Volt for the RX1 and TX1 and operating the…[Read more]

Is there any updated timeline on the RS-485 half shield production? The last update was about 6 months ago.
Thanks!

No, the only official way to buy a single Mayfly is through our listing in Amazon, while 5-packs can be purchased through the Shop on this website.

It should work fine, assuming you’ve wired the device to the Mayfly properly (did you connect the Ground of the Mayfly to the Ground of the modem?) What is the operating voltage and communication voltage of the modem? The mega2560 is a 5V board, while the Mayfly is a 3.3v board.

Hi Scott, thanks for your reply! I may have been unclear on what I’m attempting to do. I’d like to poll MMW every 5-10 minutes and return the current conditions at a site, not download the all time historical data as a CSV.
Scott Ensign replied to the topic wofpy Timeout in the forum Monitor My Watershed 1 years, 11 months ago
@wcb_data: you can access csv formatted data for a parameter at a site by specifying the parameter ID. For example, I can retrieve all of the specific conductivity data for site https://monitormywatershed.org/sites/CR_UTFZ/ with this url: https://monitormywatershed.org/api/csv-values/?result_id=5081
You can grab this url for any parameter at a…[Read more]
