I’ll get my hands on an antenna and go from there.

I’ll give that APN a try, but it seems more likely that the antenna is the issue. I was under the impression that these modules had built in antennas that would work in areas with high signal strength. Is this incorrect? Do you have antenna suggestions?

Dave

I am struggling to post data to MMW with a Digi Xbee 3 cell module (https://www.digi.com/products/embedded-systems/cellular-modems/xbee3-cellular-lte-m-nb-iot#partnumbers) and am looking for suggestions.

I have successfully used the “Logging_to_MMW” to post data with a Xbee WiFi module, but when I switch over to the cell module, I…[Read more]

Unfortunately, I am still having trouble posting data to the web. I had this working before the switch to Limnotech, so I’m wondering if there are some other changes that I’m unaware of that could be causing the problem.

I’m attempting to post data using the “logging_to_EnviroDIY” sketch on GitHub (after updating the…[Read more]

I understand that recently the data.envirodiy.org database was transferred from Utah State University to Limnotech. I’m guessing that this had an impact on the destination IP address that I need to put into my wifi xbee module?

Did the IP address change? What is it?

Many many thanks!
Dave

The specs indicate 4-12, but during the day my battery voltage often tops out around 14 or so. Will this be a problem?

Thanks!
Dave

Can you provide a little bit of example code that demonstrates how to put the MCU to sleep?

Thanks
Dave

We got one working yesterday — still fooling around with the other one.

Thanks for the helpful posts!

Any insight would be excellent.

A basic question about power:
Ideally, we would like to use 12V ~7aH AGM lead acid batteries to power the Mayfly instead of the 3.7V LiPo. We are planning to use the Mayfly for a pretty power intensive sapflux installation that requires small heaters to be powered directly off…[Read more]
