I’m looking for a good resource on how stream conductivity depends on the nature of the underlying geology.

There’s no easy way to tell your Mayfly sketch to wait longer on initial startup, the instructions for that are buried deep in one of the supporting library files and not in the main sketch. Usually just having the larger antenna and using it in an area with known strong cell signals during the initial activation is all that’s necessary.
One o…[Read more]

You’re right! I had pulled the SIM card out to get the ID and apparently didn’t quite push it in far enough, so I’m back to the “Could not connect to internet for clock sync.”.
The antenna is that little green one (I don’t see a part number/name but I assume you know what I mean). I’ll look into getting the bigger one.
While I wait on the…[Read more]

If the Mayfly reports “could not wake modem for clock sync” then that means there’s no communication between the Mayfly and the cellular module. That usually happens when then cell module isn’t properly seated all the way in the Bee socket or the pins aren’t aligned properly. If the bee module is correctly installed, the clock sync part of the s…[Read more]

The APN for US Cellular is “uscc05836.enterprise3.usc-cdp”. Southern WI is one of the few places US Cellular has dedicated towers and the signal is good (from what I’ve been told)….but if somehow the Verizon tower is what’s being hit that would make sense. I’ll try ordering a Hologram card to jump start this project (I don’t think that’s a…[Read more]

What is the APN name that US Cellular gave you use? Is the SIM card activated? Have you ever used that particular SIM card on another cellular device, like a tablet or phone? Are you sure that there is sufficient US Cellular coverage in the area where you’re using the board? They don’t actually own any cell networks, they just piggy-back off…[Read more]

We can see some data usage from the SIM card…so it maybe it just needs a longer time before “Putting modem to sleep”?

Setup:
I’m using this sketch:

I’m pretty confident I have changed the following code correctly: APN connection name (line…[Read more]

Hi @shicks and @srgdamiano. You’re not going to believe it but the addition of the build flag below has fixed my problem, at least for the Gen2 sensors.
I am certain it is this build flag and not the voltage pin (previously set to 5v) because I uploaded my script prior to switching the voltage pin over and it su…[Read more]
