Step 5: Order a RileyLink Compatible Device

Time Estimate

  • 15-20 minutes to read about RileyLink compatible devices
  • 15 minutes to order a device


  • Decide what kind of RileyLink compatible device to buy
  • Order your compatible device


  • What is a RileyLink Compatible Device? RileyLink refers to both the communication protocol and the name of the original device. Other DIY Loopers have created RileyLink Compatible Devices that use the RileyLink protocol. At the current time, RileyLink, OrangeLink and EmaLink devices are available for purchase and all can be used interchangeably with Loop.
  • Do I have to buy one? These are open-source hardware devices, but it takes special skills to build them yourself. It is recommended you buy one (or two).
  • "What happens if I lose my RileyLink compatible device or walk away from it?" Within a half hour, your pump returns to normal scheduled basal rate
  • "Can I swap out RileyLink compatible devices at any time?" Yes, you can. You do not need to start a new pod or rebuild the Loop app. Tap on the pump menu in Loop settings to search for new devices and enable Loop to create a Bluetooth connection. You can swap between RileyLink, OrangeLink, EmaLink or some future RileyLink compatible device.
  • "How close does the RileyLink compatible device need to be to me? Do I have to carry it with me?" See RileyLink Compatible Device Range.

The RileyLink compatible device is an open-source hardware device that can bridge Bluetooth Low Energy (BLE) to the radio-frequency wireless communication used by select Medtronic and Omnipod pumps. What does that mean to you? It means the device is the communication highway between your insulin pump, CGM, and iPhone.

The next version of Loop (currently being tested in the dev branch) will have DASH support (the pod with the Blue needle cap - direct Bluetooth to the phone with no need for a RileyLink compatible device). Please - be patient. If you are not already an experienced Looper willing to test code under development, wait until this code is released.

The released version of Loop will not work without a RileyLink compatible device.

The RileyLink protocol defines a specific bluetooth interface and way of opening a Sub-GHz radio channel to pumps. All RileyLink compatible devices follow the RileyLink protocol.

There used to be just one option, the original RileyLink. Now there are more options, so you have to make a decision. Depending on your choice, be sure to have the correct charger and cables or batteries handy and add spare compatible supplies to your diabetes go-bag.

While you are waiting for the RileyLink compatible device to arrive, you can proceed with these build directions all the way through Step 14. After that, you'll have to wait for your device. You can't properly enter any settings or pump info in the Loop app without it.

The population of DIY loopers (Loop and Android APS) has grown enough that you might be able to find someone local to loan you their spare.
