Sits between dexcom share and xdrip clients.
- dexplex gets BG data from dexcom
- save historic records
- provides interface for xdrip --> http://host/api/v1/entries.json?count=1
- can reduce the load on dexcom by having many clients connect
Dexcom produces a CGM (continuous glucose monitor) and has a 'share' interface to allow caregivers to monitor a user. Opensource projects such as xDrip+ https://jamorham.github.io/#xdrip-plus provide excellent alternative monitoring solutions for android. xDrip can connect directly to dexcom share or you can setup your own server with https://github.com/nightscout
logs bg log is blood glucose log dexplex log is app logging
