How to set up Nightscout with Medtronic and Android

Updated: Sep 16

Setting up your Nightscout can be a little tricky. This tutorial walks you through setting up your account with a Medtronic 6000 series pump on Android. For iOS, Nightscout supports the MiniMed Connect. Instructions are available here.


We cover how to set up Freestyle Libre and Dexcom devices with Nightscout in other posts.


What is Nightscout?


Nightscout is an open source DIY project that allows you to view your Medtronic, Dexcom, or Freestyle Libre data from any web browser for free. Nightscout sends your blood sugar data into the cloud, so you can view it remotely and use it in many interesting ways.


Nightscout was developed by a tech-savvy group of parents of children with type 1 diabetes as a solution for remote monitoring. Parents can use Nightscout to monitor their child’s blood sugars in real-time, reducing stress throughout the day.


What do you need?


To connect Medtronic pumps with Nightscout, you will need to use an Android smartphone.


Setup Instructions


We’ll first walk you through the general setup requirements and then go into the details specific to Medtronic devices. Its highly recommended you go through this process on a laptop or desktop computer rather than a mobile device.


1. Create a Github Account


First thing you’ll want to do is create a GitHub account. Select the free individual plan, and verify your email.


Next, you’ll want to navigate to this Nightscout GitHub repository. Click on the “Fork” button to make a copy of the repository so you can use it for yourself.





Once you have your own forked copy of the repository, you should notice that the page URL is now github.com/your_github_name/cgm-remote-monitor. Bookmark this page so you can easily go back to it.


2. Create a Heroku account


Heroku is the easiest way to host your Nightscout website for free. Using this platform means you will be able to see your real time CGM data in the cloud.


Sign up for Heroku. Make sure to select Hobbyist in the role field and Node.js as the development language. Verify your account by clicking on the link they send to your email address.




3. Connecting your Github and Heroku accounts


Go back to your forked version of the Nightscout repository that you bookmarked. If you didn’t bookmark the page (tsk tsk!), you can also access your forked version of the repository by clicking on your profile and then navigating to “Your Repositories”.


Scroll down to README.md and click on the purple button “Deploy to Heroku”.



This will take you to Heroku, where you should be already signed in. Fill in the following required information:

  • App name: Choose your app name! It will appear in your Heroku URL like your-app-name.herokuapp.com

  • Region: Leave this on United States even if you are located in another country. This setting will not affect your Nightscout.

  • Config_vars are the configuration settings to your Nightscout and we’ll be changing and filling out some of them. Each setting has a description underneath it. You can always change these at a later time if need be.

  • API_SECRET: This is your password. It must be at least 12 characters long. Record this somewhere as you’ll need it later!

  • BG_HIGH & BG_LOW: These are your high and low thresholds. When your blood glucose is outside of this range, you’ll get an alert (only if ALARM_URGENT_HIGH and ALARM_URGENT_LOW are turned on).

  • DISPLAY_UNITS: Choose if you want blood glucose units in mmol/L or mg/dL.

  • BRIDGE_SERVER: If you’re anywhere outside of the US, set this to “EU”. Otherwise, leave it as “US”.

  • ENABLE: Enter “careport basal mmconnect”.

  • MMCONNECT_USER_NAME: Enter your Minimed CareLink account name. This will be the same user name as what you use to log into the MiniMed Connect app on your phone.

  • MMCONNECT_PASSWORD: Enter your Minimed CareLink account password. This will be the same user name as what you use to log into the MiniMed Connect app on your phone.


Once you’re done with the above, click “Deploy App” at the bottom and enter your credit card information on the next screen. Don’t worry! This is a free service and you won’t be charged. This is just for account verification purposes. This can take up to 10 minutes.



If you get an error message after saving your billing information, click on “Deploy App” again and it should work.


4. Setting up your Nightscout account


At this stage, you should see a notice that your app was successfully deployed. Click on “View” at the bottom of your Heroku page. This will take you to your Nightscout account.




Choose your timezone.



At the bottom of the page, click on “Authenticate”.  Enter your API_SECRET (the password you created earlier). Then, click “Save”.



Once saved, remove “/profile” in the URL displayed at the top of your browser and press ‘enter’ on your keyboard.



You’ll be redirected to your Nighscout homepage. It will be empty right now, but don’t worry. We will be connecting your CGM data in the following steps.


5. Connecting your Medtronic Pump

You will need:

  1. USB OTG cable

  2. Contour Next Link 2.4 BG meter

  3. Medtronic 6000 series pump

First, you need to link the pump and meter. To do this, you need to:

  • Make sure the time is correct on your pump and that it is fully charged

  • Place the pump and meter next to each other

  • On the meter, go to Setup > Pump Options > Connect to pump

  • Click “Yes”, then “OK”.

  • Click “Auto Connect” on the meter.


Then, on your Android smartphone navigate to Security in your settings. Ensure that Unknown Sources is toggled on. Then, download the 600 Series Uploader APK to download the app. The app isn't available on Google Play, which is why you must turn on Unknown Sources. You can turn this setting off after downloading the APK.



When you first open the app, accept the permission request to run in the background.


Then, click on the three bars on the top left to enter the menu.



Tap on Settings, and under Sharing, tap on “Send to Nightscout”. Then, add your Nightscout URL and API_SECRET from earlier. Your Nightscout URL should look similar to https://test-nightscout-rachael.herokuapp.com.



Return to the homepage and plug in your meter to your pump using your USB OTC cord. Next, click on “Register USB stick” and follow the instructions.


Return the the app homepage and tap “Get Now”. Your Medtronic device should now be connected to Nightscout. If you need any additional support, you can join the Nightscout for Medtronic Facebook page.


Congratulations! You've successfully connected Nightscout with your Medtronic pump!
