Today, I got the Dexcom talking to a Teensy 3.1 and a Circuits@Home Usb Stick. Each of these boards is 0.7" X 1.5". I've had these around for about a month, and they've been frustrating me. Finally set aside today, as a day of failure, to work through the assorted issues.
FYI, I'm accumulating boards and watches at an alarming rate.
My problem here, is I was trying to just get the Chronos working with these circuits, since, in my mind, it's simpler. Finally on a whim, I broke the code out for just the Dexcom, and it works.
I can plug yet another stick of gum size board into this mess, and I'll have either bluetooth or Ant+. At this point, I may go with Ant+, simulate a HR packet, and use a Timex Ironman Watch. I don't own that watch yet though...
The Ant+ dongle is insanely small, I'll attempt soldering that tomorrow.
