Updating the Pump Software

Updating the Pump Software

Eligible pumps with an available update may do so remotely using the mobile Tandem Device Updater, giving you access to new software features.

Before you begin, make sure:

  • You are logged in to your Tandem account on your Tandem Mobi mobile app
  • Your pump battery is at least 30% full
  • Your smartphone battery is at least 50% full
  • Your smartphone is connected to the Internet
  • Your smartphone has at least 4 MB of storage
  • Your cartridge is ready to change and you have a new cartridge set on hand
  • All alerts and alarms have been cleared

To update your pump software in the Tandem Mobi mobile app, perform the following steps:

  1. From the Navigation bar, tap Settings.
  2. Tap Pump.
  3. Tap Pump Software Update.
  4. If you have not completed any applicable training, tap Go to Tandem Source. Otherwise, you will automatically proceed to Step 5. A new Internet window opens on your smartphone and displays the Tandem Source platform. Complete all required steps on the Tandem Source platform to proceed.
  5. Resume on the Tandem Mobi mobile app, and tap Download. The Tandem Mobi mobile app will begin to download the pump software update.
  6. Tap Next.
  7. Complete the items in the Important Safety Information checklist. Tap the radio button next to each statement to check all items. DO be prepared to inject insulin with an alternative method in case you encounter any issues while updating your pump. Failure to have an alternative method of insulin delivery can lead to very high blood glucose (BG) or Diabetic Ketoacidosis (DKA).
  8. Tap Next.
  9. Stop all insulin delivery. Tap Actions from the Navigation bar. Then tap Stop Insulin , and then tap Yes.
  10. Disconnect the infusion site from your body.
  11. Return to the pump software update steps. From the Navigation bar, tap Settings, then tap Pump Software Update.
  12. Your Tandem Mobi mobile app will return you to the Software Update screen. Tap Next.
  13. Tap Install.
  14. Tap Install & Restart. The pump software update process will begin.
  15. Once the update is successful, tap Dismiss.

You will need to reset the cartridge before you may resume insulin delivery. Tap Load Cartridge to do that now, or tap Go to Dashboard to do this later. If you had an active CGM sensor session when you started the update process, you will need to resume your CGM sensor session. See Managing Your CGM Session for more information.
