I have a friend who's young daughter has type 1, and he's asked me to help him, as he's really not technical at all. What this does mean, is that I know almost nothing about diabetes.
However I am a maker, and used arduino, raspberry pi, code in python etc...
He has a 640G minimed pump, which connects via BT to a contour next link 2.4.
That then plugs into a phone, and data is transferred.
The mechanism as I understand it, as that an app called nightscout sends a data request and sends the results to xdrip, which then can send out notifications to follower apps.
The thing is, that as she starts school, they can't be there every 10 mins to take readings (she is up and down in an extreme fashion and needs constant measurements).
So, first idea was to connect to OTG, connected to a tiny phone, and go.
However all the tiny phones don't support OTG, we tried rooting a "jelly" phone, however were unsuccessful.
This works with a larger phone, however 1) it's not possible for a tiny shy girl to carry a big phone around (already self conscious), and 2) the OTG cables seem to break the phones port after a while.
Next solution was to connect a pi, (zero-w) and a small lipo battery, and have that read data, and either send it out via some SIM onboard, or via BT to another phone.
Problem is, that I don't know right now how all these different apps and devices are going to talk to each other, and push/pull data.
I started to think that surely someone, in fact lots of people, must have done this before, hence my post here.
Can anyone point me at a solution for this, assuming we need to use the 640g, and understanding that I don't mind building, soldering, coding, 3d printing etc.. as long as there are decent guides out there to follow.
I have googled a lot, and didn't really find anything that seemed to hit the spot, yet, it can't be an uncommon requirement.
Thanks in advance, and apologies for my lack of knowledge, just trying to help a little girl here :-(
