How does the t:slim X2 insulin pump work with Dexcom G6 CGM?

The t:slim X2 insulin pump is integrated with the Dexcom G6 CGM, allowing you to view your CGM value,  graph, and trend arrow, as well as receive any Dexcom alerts and alarm, right on your t:slim X2 pump. Additionally, both of Tandem’s predictive technologies, Basal-IQ technology and Control-IQ technology, rely on readings from the Dexcom G6 CGM to operate.
