What is Dexcom One?
Dexcom One is a newer CGM option from Dexcom. It is intended to be a more affordable and accessible option for people with diabetes.
With the introduction of Dexcom One, Dexcom now has two classes of CGM systems. While the G6 and G7 apps offer a range of automated alerts and allow users to give family members and healthcare providers real-time access to their readings, the Dexcom One app is much simpler. Users can program their own alerts into the software and view their glucose readings but aren’t able to automatically share the data with others.
As of September 2022, Dexcom One is sold in limited markets (Bulgaria, Estonia, Lithuania, Latvia, and the UK).
Dexcom One Calibration Code Conversion
Dexcom One sensors can be used with G6 transmitters and vice versa. However, the calibration code used must be converted to a different value when your sensor and transmitter are not of the same type. These calibration codes are definitely useful for anyone using the Official G6 App with an Anubis transmitter and Dexcom One sensors.
Behind the calibration codes are some calibration parameters, which the apps send to the transmitter. Dexcom G6 and ONE use different codes, but the same parameters – see the cross-reference table below.
xDrip and xDrip4iOS already have native support for both so these codes are not necessary for those users.
