Name: CGM Datafield 2 (xDrip+, AAPS, Nightscout)
Author: andreas-may

This data field is an update of my xDrip+/Spike/Nightscout data field. The main change is that the values are now queried with a foreground process, so that more frequent queries are also possible (e.g. every minute). It shows your CGM bloodglucose readings directly from xDrip+ app (Android only), AAPS (Android only) or with a web request from your Nightscout installation.

+++++

FEATURES

- Last bloodglucose reading (mg/dl and mmol/l), delta and minutes since last reading

- TBR (%), IOB and COB (AAPS only)

- Possibility to write bloodglucose and in Closed Loop mode also TBR, IOB and COB to the fit-file of your activity and see the values in Garmin Connect.

+++++

PLEASE READ THIS ADVISORY

Never make a medical decision based on a reading that you see on this data field, it's NOT a medical device! Always perform a fingerstick blood glucose check first.

README and HELP

The readme of my watchface also answers questions that may arise in connection with this data field:

It is highly recommended to inform yourself there about the setup and possible problems!

+++++

INSTALL COMPANION APP

You need to install the xDrip+, AAPS or Spike app or get readings via web request from Nightscout:

https://github.com/NightscoutFoundation/xDrip/releases

https://jamorham.github.io/#xdrip-plus

https://github.com/Nightscout/AndroidAPS/

You didn't find these apps in app stores!

+++++

To enable communications between this datafield and the Android companion app xDrip+ you have to enable “xDrip Web Service”, "Open Web Service" must be disabled (xDrip+: Settings - Inter-app settings).

AAPS can also be queried directly. You need v3.2.0.4 or newer. Activate the Garmin plugin in the Config Builder, but do not define a request key (leave the field blank).. If you like to see your loop status you must enable AAPS as data source, xDrip+ status line isn't supported anymore.

Another way to view your CGM data is to query the Nightscout values via the internet. Please enter your URL _WITHOUT_ "https://" and "/api/etc."!

+++++

SETTINGS (via GARMIN MOBILE CONNECT or GARMIN EXPRESS)

Choose AAPS or xDrip+ as data source. If Nightscout URL is selected, your Nightscout URL must be entered (e.g. "myname.herokuapp.com" without "https://" and without "/api/v1/").

Enable saving diabetic data to the fit-file of your activity.

Adjust the delay of the request.
