We ordered a couple of these modules and they arrived a few days ago. I did some testing the past couple days and had only occasional success at sending data to MMW with them. We’re thinking the code libraries probably need to be tweaked to work with these new modules, but there’s no usable electrical or software documentation for these p…[Read more]

Thanks Sara, that is good news. I will be ordering several of these to replace the modems at all of my sites. The previous version was not that reliable, so I am hoping they made some improvements to the design in this version. I will make sure to use “transparent mode” in my sketches.
Sara Damiano replied to the topic New Xbee Modem: XB3-C-GM1-UT-001 in the forum Mayfly Data Logger 1 year, 11 months ago
According to the product change notification you attached, there shouldn’t need to be any software changes for “transparent” mode, so most of the examples for ModularSensors should still work.
The underlying cellular chipset on the board *has* changed from the ublox SARA R410M to the Telit ME310G1-WW on the global version or the Telit ME310G1-W1…[Read more]

You can also try disconnecting the solar panel for a few days since you’ve got a fully-charged battery on it. Then that’ll tell you if there’s any correlation between the sensor noise and charging activity. On a few rare occasions, a failing solar panel ended up generating noise on CTD sensor data.

Yeah – the sensor was cleaned recently. I had also switched the logger on and off. I’ve now replaced the battery. No luck – the trough and flickers, though slightly modified, still occur. I’ll try to substitute in another sensor, possibly another logger, in order to isolate the problem.

Thanks Shannon! Some testing and an example sketch would be very helpful.

That’s a good find. We haven’t tried one of those with the Mayfly boards yet, but we’ll have to buy one and see what all might be needed to get it to work properly. Previous Digi boards required our now-discontinued bee adapter board to change the pin assignments and power supply options in order to work with the Mayfly v0.5 boards. But the…[Read more]

Hello EnviroDIY,
The Digi Xbee modem XB3-C-A2-UT-001 was recently replaced with a new version: XB3-C-GM1-UT-001. The product change notification (attached) claims that the new modem is a “drop in replacement” for the discontinued model. Before I put in an order for these to replace my older, failed Xbee modems, I wanted to check with the forum…[Read more]

@tumayflybearriver – thanks for brining it up. Its nuts, but looks to me like the signature of “thrown away data” by ModularSensors software that runs on the Mayfly, and the ODM2 software on monitormywatershed.
I’ve raised the issue of reliable delivery in 2018, and implemented it on my systems and offered it to the mainline Modu…[Read more]
