Finally, the 8.2 release has it. Here's this morning:
So, first impression, the graph is basically, useless. Upper line is 300, middle line is 110?
I thought I could zoom in on the points by double tapping, nope. And the time scale is fixed, 12-12.
A potential positive here, all I needed was an app writing glucose values to healthkit. Theoretically, any other app should be able to subscribe to that data with the Users permission. That could be major, real time access to your data from any approved iOS application.
So we might see a proliferation of iOS apps that handle CGMS data in some capacity, certainly something better than what's above.
On another note, the new model died after 2 months. First of my devices to malfunction. Probably due to the wire wrap wire, jumpers that I used. Redesigned the board, with only two jumpers, and relocated the connection points to where they are easier to access. Routed the slot for the crystal, "carefully" this time, and relocated some of the traces so I wouldn't be cutting them...
Top trace isn't so pretty, I had to touch that up with a sharpie before etching.
On the XCode side, upgraded to whatever version supports 8.2. Found that breaks the ability of my iOS app to reconnect BLE from the background. I spent allot of time getting that to work. Luckily, recompiling my app as 8.1 appears to solve that issue(for now), until I figure out how the code is supposed to work.
Finally, it's easy enough to write data to healthkit, if you start with the Heart Rate example. The tricky part is getting the units correct. The closest unit of measurement you can choose is g/L. If you're using mg/dl, you'll need to divide that value by 100 before writing to healthkit.
