Add Pump

Pump Choices

You can choose a pump from the Heads-Up-Display (HUD) or from the Loop Settings screen.

The HUD looks like the graphic below if no CGM or Pump is chosen:

Switching Pumps?

To change the pump connected to Loop go to Change Pump Type.

Loopers can choose from 3 pumps and a simulator:

  • Minimed
    • Note: only some Minimed pumps are compatible
    • Please refer to Compatible Pump for additional details
  • Omnipod
  • Omnipod DASH
  • Insulin Pump Simulator

Omnipod Terms

The Loop app and LoopDocs use these terms:

  • Omnipod is the older (Eros) pods (requires RileyLink compatible device to Loop)
  • Omnipod DASH is the newer BLE pods (phone talks directly to pod - no extra device needed to Loop)
  • Omnipod Common means information common to Omnipod and Omnipod DASH

After you complete these screens, you select the insulin type.

Insulin Type

For all pumps, you can choose from the insulin types below.

  • Insulin Type
    • Rapid Acting (Novolog, Humalog, Apidra) or Ultra Rapid (Fiasp, Lyumjev)
    • Inhaled insulin (Afrezza) is not offered because it is not used in pumps. Non-Pump Insulin

To add a Omnipod DASH pump, skip ahead to Omnipod Commom 2.

Omnipod and Medtronic users should continue to select a RileyLink compatible device.

Omnipod or Medtronic

For Omnipod and Medtronic pumps, you need a RileyLink compatible device to Loop. The Device and your phone must be kept close to your pump for Loop to work.

A new RileyLink compatible device is not listed next to its slider until after you connect the device to Loop. Find the little toggle in the device list, switch on that toggle, and the RileyLink will appear after the toggle is green.

You can personalize the name once it is connected to Loop.


All RileyLink compatible devices in the nearby area, not already connected to a Loop app, will display in the RileyLink Setup screen. Select your RileyLink by sliding the toggle to display green and then press the blue Continue button at the bottom of the screen.

If your device does not appear:

  • Make sure it is charged and turned on
  • Make sure it is not connected to a different phone or app

If you are adding a Medtronic pump, skip ahead to Medtronic.

Omnipod Common 2

After selecting a RileyLink for Omnipod, all other actions for Omnipod and Omnipod DASH are the same. Once a pod is paired, the Pump display is the same, except the Omnipod screen has a RileyLink Devices section.

For Omnipod (left) and Omnipod DASH (right), you should see the Pair Pod screen.

At this point - you should hit Cancel (upper right of screen) and review the Omnipod Common page before pairing a pod.

New Looper / New Podder

Carefully review the Pair Pod instructions and the rest of the Omnipod Common page before continuing. Then, when you are ready, pair a pod.

If you are not ready to fill and attach a pod with insulin, try filling a pod with water and let it drip into a ziplock bag to test running Loop on the pod. (Be sure the pod is not near anything when you hit "Insert Cannula".)

If you followed this page to add your Medtronic pump, you have completed the first three steps. If not, you can prepare your pump now, then do those first three steps using Loop (follow the links). All other steps be completed before you Connect the Pump.

  1. Select Minimed as your pump
  2. Select Insulin Type
  3. Select RileyLink
  4. Prepare Medtronic Pump
  5. Connect Pump to Loop

Prepare Medtronic Pump

No Need to Set the Time

If you just added a battery to a Medtronic pump you have not used for a while, the pump initiation screens require you to set the date and time for the pump. You can just accept the default values; when you connect the pump to the Loop app, the time and date are automatically set.

Loop requires these settings on your Medtronic pump.

Check with your users guide (can be found online if you don't have one) for more detailed instructions on your model of pump if you're not sure how to accomplish these steps.

If you have basal rates, insulin to sensitivity factor and carb ratios in your pump - these will be overwritten (using the Therapy Setting values) when you connect your pump to Loop. If those rates are important to you, record them prior to continuing.

  • Turn off Patterns under the basal menu settings.
  • Set the Max Basal and Max Bolus values in the Medtronic pump to be greater than or equal to the values you enter in the Loop Therapy Settings. Otherwise, Loop will not connect to your pump with the error message: Pump Error. Max setting exceeded.
  • Set your pump's Temp Basal Type to Insulin Rate (U/hr).
  • Set Remote Devices to ON and enter any random ID (010101 will work - avoid using all zeros). This setting is found in the pump's Utilities menu (for x23 continue to Connect Devices, Remotes) and turn ON the Remote Options.
  • Cancel any currently running extended or dual wave boluses. Loop cannot loop with those running.
  • If you are using an Enlite CGM through your Medtronic pump, make sure that is configured properly before adding your pump to Loop

Connect Pump to Loop

The final step is to connect your Medtronic pump to Loop.

  • Make sure your RileyLink is turned on and nearby
  • Add your pump's region, color as shown in the graphic below
    • Note that some Canadian pumps use CM instead of CA for the region code. Select CA/CM in the dropdown menu.

how to add country code and color for medtronic pump

  • Add your pump's 6-digit serial number as shown in the graphic below
  • Click the Connect button to connect the pump to Loop.
  • The spinning icon continues until you see the blue check mark and Continue button
    • If Loop is not successful at connecting, you will get an error message and stay on this screen
    • If the Delivery Limits (max basal and max bolus) in the pump are lower than values you entered in Loop you will see an error message: Pump Error. Max setting exceeded. (See note below for other reasons you might see this message.)
      • In this case, edit the values in the pump and then click Connect to retry.

how to enter serial number for a medtronic pump

Max setting exceeded

It turns out the "Max setting exceeded" error might be displayed even when Max Bolus and Max Basal Rate are already set appropriately on the pump.

  • If you had previously used a pump that allows multiples of 0.025 U/hr basal rate and you have one of those rates in the basal rate schedule in Loop, you will not be able to connect to a different Medtronic pump that does not support those rates.
  • If this happens to you, cancel out of connecting to that pump
    • Refer to Prep for Medtronic on the Settings page
      • Add a simulator so you can Change the scheduled basal rates
      • Delete the simulator
    • Try again

Bolus in Progress

If you get an error Bolus in progress on the pump when trying to connect, you probably need to rewind and load insulin into the reservoir.

If the pump has alerted that it is out of insulin, you cannot pair to Loop as a new pump.

Final steps

Once you have successfully connected to the Medtronic pump, click on Continue:

  • You will then be presented with two more screens, click Continue for each
    • Pump Clock message
    • Pump is ready for use screen
  • If you have an x23 or x54 pump, there is one more step - highlighted below

For x23 and x54 Medtronic pump users only

img/pump_broadcasts.png For x23 and x54 Medtronic pump users, there is a packet of information special to those pumps called MySentry messages. If you have never setup this part of the pump previously, you may see a screen, called "Pump Broadcasts", at this point in the setup process.

Follow the directions on the screen. They will require you to take some manual steps on your pump to "pair" it with your Loop app.

Basically, you will need to go to your pump's main menu, scroll down to Utilities, then Connect Devices, then Other Devices, turn that setting On, and then select Find Device. Once you do that, click on the Continue button in Loop app and the pairing will take place. This will allow those MySentry packets of information to flow to Loop app.

This step does not apply for x22 or x15 pump users, since those pumps do not have MySentry capabilities.

Now that your pump is paired with Loop, you should select the type of battery you are using and decide whether to use My Sentry:

  1. Select your pump's battery type (lithium or alakine)
  2. Leave the Preferred Data Source on Event History
  3. If you have an x23 or x54 pump, choose whether to use My Sentry (saves phone battery) or not (saves OrangeLink battery)
    • For other Medtronic pumps, adjusting this setting does not do anything
    • Note that the Orange Link battery drain is substantial
      • Some users reported batteries needed to be changed every 2-4 days compared to 10 days with MySentry off

The Medtronic status and commands available are shown in the Pump Settings page.

Change Pump Type

Before changing from one pump type to another pump type, you must delete the old pump type.

  • If you are using Medtronic, scroll to the bottom of the pump screen and select Delete Pump

  • Before switching between Omnipod and Omnipod DASH or any kind of Omnipod to Medtronic, you must deactivate your current pod

    • This does not include changing a pod, so long as the pods are of the same type
    • The Switch to other insulin delivery device button will not be available with an active pod
    • Follow along in the GIF below - it cycles though these steps.

      • Go to the Omnipod screen and tap on Replace Pod
      • Deactivate the pod
      • When deactivation completes, tap on Cancel in upper right
        • If you hit continue instead, tap cancel when Pair Pod screen appears
      • On the main Loop screen, tap on the ! No Pod icon
      • Scroll to the bottom of the screen
      • Tap on Switch to other insulin delivery device and follow the directions to complete the task
    • Now the new pump type can be selected from settings or tapping on the add pump icon on the HUD
