Dexcom G6 and ONE

Basics first

• Follow general CGM hygiene and setting sensor recommendation here.

General hints for looping with G6 and ONE

• Recent transmitters are called Firefly. Sensors cannot be restarted without removing the transmitter, which itself cannot be reset, they also do not generate raw data.

• If you are restarting sensors, ensure you are ready to calibrate and keep an eye on variation.

• Pre-soaking of the G6/ONE with factory calibration is likely to give variation in results. If you do pre-soak, then to get best results, you will probably need to calibrate the sensor.

If using G6 or ONE with xDrip+

• If you are using a recent (Firefly) transmitter, preemptive restarts are ignored.

• If you are using a modded transmitter you do not need to use preemptive restarts.

• If you are using an old rebatteried transmitter, the safest thing to do is disable preemptive restarts. Though, in this case you will have to use the G6 in non-native mode (which is unadvisable as it disables factory calibration and doesn’t filter noisy readings), or else the sensor will stop after 10 days.

• The Dexcom G6 and ONE transmitters can simultaneously be connected to the Dexcom receiver (or alternatively the t:slim pump) and one app on your phone.

• When using xDrip+ as receiver uninstall the Dexcom app first. You cannot connect xDrip+ and Dexcom app with the transmitter at the same time!

• If you need Clarity and want to profit from xDrip+ alarms use the BYODA (only G6) with local broadcast to xDrip+.

• You can also use xDrip+ as a companion app of the official Dexcom app, but you might experience delays in BG readings.

• If not already set up, download xDrip+ and follow the instructions on xDrip+ settings page.

• Select xDrip+ in in ConfigBuilder, BG Source.

• Adjust settings in xDrip+ according to xDrip+ settings page

If using G6 with Build Your Own Dexcom App

• Build Your Own Dexcom App (BYODA) supports local broadcast to AAPS and/or xDrip+ (not for G5/ONE/G7 sensors!)

• This app lets you use your Dexcom G6 with any Android smartphone.

• Uninstall the original Dexcom app or patched Dexcom app if you used one of those previously (do not stop the currently running sensor)

• Install the downloaded apk

• Enter sensor code and transmitter serial no. in patched app.

• In phone settings go to apps > Dexcom G6 > permissions > additional permissions and press ‘Access Dexcom app’.

• After short time BYODA should pick-up transmitter signal.

Settings for AAPS

• Select ‘Dexcom App (patched)’ in in ConfigBuilder, BG Source.

• If you don’t receive any values select any other data source, then re-select ‘Dexcom App (patched)’ to trigger the demand for permissions to establish the connection between AAPS and BYODA-broadcast.

Settings for xDrip+

• Select ‘640G/Eversense’ as data source.

• Command ‘start sensor’ must be performed in xDrip+ in order to receive values. This will not affect your current sensor controlled by Build Your Own Dexcom App.

New transmitter with running sensor

If you happen to change transmitter during a running sensor session you might try to remove the transmitter without damaging the sensor mount. A video can be found here. If you opt for this solution instead, you must be careful to avoid damaging sensor contacts with the strip.
