Dexcom G7

Fundamental in advance

In spring 2022, the Dexcom G7 received its CE certificate and was sold at the end of October ‘22.

Noteworthy is the fact that the G7 system, compared to the G6, does not smooth the values, neither in the app, nor in the reader. More details about this here.

Smoothing method

Exponential Smoothing MUST be enabled for meaningful use of the G7 values.

1. Patched Dexcom G7 App (DiAKEM)

Note: AAPS or higher is required!

Install a new patched (!) G7 app and start the sensor

A patched Dexcom G7 app (DiAKEM) gives access to the Dexcom G7 data. This is not the BYODA app as this app can not receive G7 data at the moment.

Uninstall the original Dexcom app if you used it before (A running sensor session can be continued - note the sensor code before removal of the app!)

Download and install the patched.apk here.

Enter sensor code in the patched app.

Follow the general recommendations for CGM hygiene and sensor placement found here.

After the warm-up phase, the values are displayed as usual in the G7 app.

Configuration in AAPS

For the configuration in AAPS

  • Select ‘BYODA’ in in ConfigBuilder, BG Source - even if it is not the BYODA app!

  • If AAPS does not receive any values, switch to another BG source and then back to ‘BYODA’ to invoke the query for approving data exchange between AAPS and BYODA.
