Now Tslim X2 Integrates with Libre 3 Plus: How Can You Pair

The recent integration between the t:slim X2 insulin pump from Tandem Diabetes Care and the Freestyle Libre 3 plus sensor from Abbott marks an important advancement in AID. This update allows users to get minute-by-minute glucose data with predictive insulin adjustment, enhancing control and reducing daily hassles. For those seeking CGM-compatible insulin pumps, this integration offers flexibility, particularly for individuals who prefer Abbott’s compact sensor, like Libre 3 Plus.

The update was driven by the increasing need for more choice in diabetes technology. With growing competition in automated insulin delivery (AID) and FDA approvals for interoperability, Tandem and Abbott collaborated to create a seamless system. Back in 2019, they first announced intentions to collaborate, aiming for seamless ecosystems. The 2025 rollout expands options beyond Dexcom, making advanced AID systems accessible to more users.

Overview: Pair of Tslim with Freestyle Libre 3 Plus

As of October 29, 2025, U.S. users can now pair the tandem t: slim X2 (control IQ) with the FreeStyle Libre 3 Plus via a free remote software update. This means your pump receives glucose readings every minute via Bluetooth, powering Control-IQ+ technology for automated adjustments. For existing users, the update is available through the Tandem Device Updater, while new pumps ship preloaded. This pairing expands internationally, with early programs planned for late 2025 and broader rollout in 2026. This is designed for people with type 1 diabetes (ages 2+) and type 2 diabetes (ages 18+), just focusing on predictive insulin delivery technology

Important Safety Note: On November 24, 2025, the FDA and Abbott issued a medical device correction report for certain FreeStyle Libre sensors due to incorrect low glucose readings, linked to 736 injuries and 7 deaths globally. Here is the quick guide on Libre 3 reading errors and Abbott and FDA asked you to do. (Source: CBS News)

How Tslim X2 Integrates with Libre 3 Plus

Here are the simple steps to follow for integration of Libre 3 Plus with Tandem Tslim X2 Insulin Pump.

Step 1: Confirm Device Compatibility

Make sure you are using a T:slim X2 insulin pump with the latest software update that supports FreeStyle Libre 3 Plus integration.

Step 2: Update Your T:slim X2 Software

Connect your pump to a computer and update it using Tandem Device Updater to enable Libre 3 Plus CGM support.

Step 3: Set Up the FreeStyle Libre 3 Plus Sensor

Apply the Libre 3 Plus sensor as instructed by Abbott and activate it using the compatible Libre app or reader.

Step 4: Enable CGM Pairing on T:slim X2

On the pump screen, go to Options → CGM → Pair New Sensor, then follow on-screen prompts to connect Libre 3 Plus.

Step 5: Allow Data Sharing & Permissions

Ensure Bluetooth is on and permissions are enabled so real-time glucose data flows continuously to the pump.
