Hi Shannon,

 

Thank you for the response. I ran the board attached to my computer in Arduino and the red LED3 light did come on when the sample was run. I put a voltmeter across the GND and V pins and the voltage was 3.3v when the sample was collected. It still was reading -9999 when this test was run (with the old sensor attached to the board).

 

The sketch on the 0.5b board is older than 2022 so that would explain why the new Gen2 sensor did not work. The sketch on the 1.1 board is from 2025.

Hi Shannon,

We are using the Mayfly version 1.1 board to test the Digi modems. The specific Digi modem we are testing is linked below.

Hi Shannon,

I was wondering if you had a chance to revisit the Digi modules and if so, did you have any success?

Thank you,

Caroline

Hi Shannon,

Thank you for the quick response and I appreciate your help! If you end up finding out anything, please keep me updated.

Hello,

Thank you for your quick response Bob! To be honest, I am fairly new to working with the Mayfly boards. I was wondering if anyone at EnviroDIY had any luck with the modems since this was initially posted in September and if so, could direct me to an example sketch to use that turns off the 2G fallback. Or if there is any other sketch that may have worked for you, please let me know.

Hello,

@bblumenscheid or any other EnviroDIY user who may know, I was wondering if you know whether both the Digi XBee 3 Global (GM2) and the Digi XBee 3 Low-Power (GM1) modems work on the Mayfly 1.1 board in the U.S.? We have the Global GM2 modem and we have not been able to send data to MMW successfully. It uploaded one time but has not worked since with the same sketch used.</p>
Any information would be greatly appreciated!
