    I ordered some parts and I’m back working on this. I have 4 each of Mayfly’s (v0.5b), Hologram SIMs, and XBee3’s (XB3-C-A2-UT-001). I’ve had a little trouble getting the library straight and I intend to learn and install PlatformIO, but for now I’m working on regular Arduino platform. I’m running Sara’s “logging_to_EnviroDIY” … I don’t know if…[Read more]

    OK – I’ve cleaned up my library problems as suggested. I’ve paired down the logging_to_EnviroDIY.ino to the bare minimum to check out the modem. I also turned on some debugging and I think I fixed a bug in the code that made it think it was connecting to a WiFi network. I know I got on the cellular network because it showed as active on…[Read more]

    I just received the Digi Xbee3 that I ordered a week ago. Now I need a little help with a sketch to get me started. I tried using the code that Beth suggested (Logging_to_EnviroDIY.ino) but never got it to compile. Does anyone have a simple bring-up sketch for this module? You can contact me externally at ckillen@charter.net.

    Thanks Beth and Shannon, I’m finally getting a chance to get back to this.

    I’m NOT using any sensor with the ADS115 chip so I’ll go back to my 2G setup and comment out those lines of code. I’ll get back to you on my success/failure eventually.

    The Digi XBee3™ Cellular Smart Modem, LTE-M seems to be what I want in the long run. I just ordered…[Read more]

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

    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 and it couldn’t connect either. Even knowing that, I tried to run the script that Beth suggested but couldn’t get it to compile:
    error: ‘class…[Read more]

    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 there is some documentation out there somewhere but I haven’t found what I need: a step-by-step guide for loading/personalizing/testing the configuration. I…[Read more]
