This initial release of the t:connect mobile app only allows your phone to serve as a secondary display for your pump data. We have a variety of features and functionality we intend to incorporate in future releases, but you cannot currently use the app to control any pump features or change any settings.
Tandem handles issues with the connection between your Dexcom transmitter and t:slim X2 pump, questions about calibration, the “---” display, and sensor failures after the 2-hour warmup period. To report a sensor failure after the 2-hour warmup period, visit tandemdiabetes.com/G6Form
For all other CGM issues, including sensor failures during the 2-hour warmup, “no restarts” alert, or physical problems with your sensor or transmitter, such as bleeding, bruising, skin reaction, adhesive issues, applicator issues, or broken wires, you should contact Dexcom using one of the options at dexcom.com/contact.
