Supported systems¶

xDrip4iOS supports the systems listed below. Regional sensor revisions and manufacturer changes can affect compatibility.

Direct CGM devices¶

App choice	Supported family	Important requirement
Dexcom G6/ONE	Dexcom G6, ONE, and compatible Anubis G6 transmitters	A six-character transmitter ID. Use Coexistence Mode or separate Bluetooth channels when another app or device also connects
Dexcom G7/ONE+/Stelo	Dexcom G7, ONE+, and Stelo	Choose Primary Mode for a direct connection or Coexistence Mode when another app controls the connection
Libre 2/2+ EU	European Libre 2 and Libre 2 Plus variants recognised by the app	NFC scan and Bluetooth permission disabled for the Libre app
MiaoMiao	Libre sensors supported by the attached MiaoMiao transmitter	Charged transmitter attached to the sensor
Nano/Bubble/Bubble Mini	Libre sensors supported by the attached transmitter	Charged transmitter attached to the sensor
Medtrum Nano Pump	Medtrum TouchCare Nano CGM relayed by the pump	EasyPatch must remain active in the background and receive readings

Important connection differences¶

• Dexcom G6 and ONE can use Primary Mode or Coexistence Mode. Coexistence is intended for use with the official Dexcom app or CamAPS.
• In Primary Mode, Bluetooth Channel normally uses Slot 2: Mobile App (Default). Slot 1: Receiver or Pump leaves the Mobile App channel available for another phone app but can prevent a receiver or pump from connecting.
• Compatible Anubis G6 transmitters are recognised automatically and can provide additional transmitter information, a shorter warm-up, extended transmitter life, transmitter reset controls, and an experimental third Bluetooth channel.
• Dexcom G7, ONE+, and Stelo can use Primary Mode or Coexistence Mode. Primary Mode requires the four-digit pairing code from the current applicator. Coexistence Mode relies on the official Dexcom app, CamAPS, or another compatible app and that app must remain running and receiving readings.
• Libre 2 and Libre 2 Plus EU connect after an NFC scan. Bluetooth permission for the Libre app must remain disabled.
• MiaoMiao, Bubble, and Nano devices are separate rechargeable transmitters attached to a compatible Libre sensor.
• Medtrum Nano Pump is the Medtrum patch pump connection. It is not a separate CGM named Nano. The EasyPatch app must remain running and receiving readings.

A sensor that is already running can normally be added without restarting it. Follow the device guide and keep the existing session active.

CamAPS¶

xDrip4iOS can work alongside CamAPS when CamAPS uses a supported Dexcom sensor. It cannot receive direct readings from a Libre 2 or Libre 3 sensor while CamAPS is using that sensor. This is a difference in how the sensors connect to the iPhone, not a fault in either app. See Using xDrip4iOS with CamAPS.

Follower sources¶

• Nightscout
• LibreLinkUp
• LibreLinkUp Russia
• Dexcom Share
• Shared Calendar
• CareLink
• Medtrum EasyView

Shared Calendar can receive Calendar Share readings from any release of the app, including xDrip4iOS and Zukka. The source and follower can use different releases.

Follower sources need internet access and a source account, site, or calendar that already contains current readings. They do not connect to the physical sensor on the follower iPhone.

Follower Heartbeat devices¶

The app can use a Libre/Generic, Dexcom G7/ONE+/Stelo, or OmniPod device as a background heartbeat. A heartbeat device does not provide glucose data to xDrip4iOS. It only helps Follower mode check for new readings in the background.

The heartbeat device is optional and separate from the selected follower source. It must be added in the Devices tab and selected under Settings > Data Source > Keep-alive.

Not available as direct CGM choices¶

xDrip4iOS does not provide direct CGM choices for Dexcom G4, Libre 3, Medtronic, Eversense, or GlucoMen systems. Some of these systems can still be usable indirectly if their readings are uploaded to a supported follower service.
