Sorry you got some backwards cables and a bad header.  I used to inspect all of the boards and cables closely before shipping them out, but in the most recent production run, the cables were sealed in a foil bag along with the adapter board, so we weren’t able to see them properly.  You can fix the backwards polarity cables yourself.  Just use a…[Read more]

Thanks Heather! I think I’ve got in now. 🙂

This sketch is also available here: https://github.com/ScottEnsign/SDoutput. I’d welcome input and refinement.

Ok, thanks Neil. I’ll look into it.

@zeke-holloman  I’ve been out the office. Just to summarize our offline investigation – I got a good POST using your thingspeak settings. It seem to me that its your modem data plan that isn’t connecting in some way. Maybe there is a better error indication from DigiXBeeCellularTransparent, but its an evolving area to make it easy.

@vogelrnws nice to se the layout. That battery holder looks pretty solid and as you said 2 *12V * 9Ah gives 216WHr of capacity. a LiIon at 4.4AH @ 4V is 16Ah.
Its great to have a discussion about the mechanical side, what works, what doesn’t work so well.
Seems like on of the challenges is that uSD is right up against the side of the cabinet -…[Read more]

New Mayfly boards and cool new accessories will be here very shortly, still waiting for the shipment, and then we’ll need time to turn things around and get the shop restocked, but it should be very soon.  We’ll be making a blog post soon about all the updates to the hardware and accessories in about a week or so, and then things should be ready…[Read more]

I’ve had some people ask me how to get hold of boards.
Just wondering, I know there has been a worldwide shortage of some parts, but is there any update of when the boards might be available? many thanks

No, the apn would need to be loaded via XCTU or you can place it in the python code before the cellular connection action…

xbee.atcmd(“AN”, “hologram”) —–or whatever your apn is

conn = network.Cellular()

@vogelrnws Ah, ok! Awesome, thank you. And is there a place to put the apn in the main code?

Any arduino code you would like to use. The key is to identify which serial port you have connected to the XBee. For instance if you have it connected to Serial1 then you would want to print out the statements you want sent to Thingspeak like so…

Topic posting to includes multiple fields

Serial1.println(#Pfield1=60&field2=45)

@vogelrnws Hi there! So I uploaded the files onto the Xbee and used a python editor to change the main.py file. Is there any arduino code you would recommend using alongside this approach?

Awesome, thank you. That worked

@vogelrnws Ok, thank you. If you need my email, zholloman54@gmail.com

it seems I have to add your contact email to allow the share. I’ll see if I can post the zip file. It didn’t like the .py files before

@vogelrnws I was spending some time looking at the cellular stuff and I decided I’d try to use the python example you used, but I can’t seem to access the files through the Google Drive. Also, I don’t think I currently have a python editor. What is a good one that you would suggest? Thanks
