        I have very recently purchased a Mayfly, GPRSBee (with SIM800H) and a Hologram sim card. Finding information on how to get the cellular communication working has been a nightmare. I’m sure the

          Hi Cal,

          I have been working on a tutorial, but it’s unfortunately nowhere near complete, and I will be away for the next week. I suggest using the Modular Sensors library on GitHub, where there

            The modular sensors library that Beth references depends on TinyGSM for the majority of the cellular connection process. You may want to look at the code and examples in that library for help communic

                Hi Beth-

                I downloaded your tutorial that you started a 1 1/2 years ago.  Is there any chance you finished it?  It looks like just what I need as and Arduino IDE user trying to transition to Platfor

                Thanks for your posts Beth and Sara. The more I look into this, the more I believe that Sara is right; I just don’t have 2G service where I live. I found an old Raven 2G modem, plugged it in an

                    Does anyone know when 3G will be available on the Mayfly?

                      There are 3G and 4G modules that work just fine with the Mayfly. Are you meaning you want instructions on how to do it, or you’re just looking for the hardware?

                        Hi @ckillen, The Bee socket on the Mayfly makes it easy for the Mayfly to hook up with any radio with that connection/communication protocol. The socket can be used for several types of radios, includ

                              Which ADS1115 library are you using? Make sure you’re using the soligen2010 fork at https://github.com/soligen2010/Adafruit_ADS1X15/ – Don’t use the Adafruit original.

                                      Hi Cal, there’s a thread on GitHub about getting this thing up and running. Looks like others are having trouble as well. Perhaps contributing your debugging will help things along.

                                          Huh.. I don’t know why the XBee would entirely stop responding. Does it still respond on XCTU? Could you have accidentally put it to sleep?
