OK, I see, thank you, that makes sense. I should be able to extend the time of >3.65V by increasing my logging interval from 5 to 30 min. I’ll keep that ‘attempt to re-send data’ project in mind as I gain experience and availability.
When my Mayfly voltage is <3.65 it is programmed to just log data and not publish (to MMW via DigiXBeeCellular)? When the voltage is good again why doesn’t it send all the data that were logged in the interim? This is a remote site so I haven’t checked to see if the data are on the SD card. The logging interval is 5 min. (I’m planning to increase…[Read more]
I bought the PulseLarson W3554B0140 RF ANT 829MHZ/2.2GHZ PCB TRACE (https://www.digikey.com/products/en?keywords=553-2574-ND) and I’m pretty sure it works. It looks like the one that comes with the Development kit (https://www.digi.com/products/models/xk3-c-n1-ut-e).
I want to try those things but don’t have enough experience yet to know exactly how. When you reference TinyGSM (increasing the timeout time) what exactly do you mean by TinyGSM? And defining the modem serial at 9600 is understandable except I don’t see where to do that (in my logging_to_EnviroDIY sketch or in a different sketch that sets…[Read more]
