Connecting the Contour Blood Glucose Meter to Allie on Android

Allie features Bluetooth integration with the Contour Next One Blood Glucose Monitor. This guide provides best practices to ensure seamless transfer of blood glucose data from the monitor to the Allie Android application.


In order to pair the device, please make sure you have done the following during the installation process, completing all of the following:

    • Allowed Allie to turn Bluetooth on
    • Given Allie access to ""Location", Nearby Devices", and "Physical Activity"
    • Confirmed that Bluetooth is turned on for your phone

Note: If you have previously used the Contour Next One application, you will also need to delete that application from your phone. Then go to your Bluetooth settings and "Forget" the previously connected device. We also recommend restarting your phone before proceeding with the pairing.

For best results, we recommend making sure that you are using the most recent versions of Allie and that your phone's operating system is up to date. More information on checking your settings/updating Allie can be found here.

You will also need to see an option for "Glucose Levels" in Allie. If you do not see this option, please check with your technician or Healthcare Provider to make sure they have set you up correctly.

Pairing Contour BGM with Allie App

  1. To get started, please make sure the Contour Blood Glucose Meter is turned off. If it is on, hold the button down until it beeps and the screen goes blank.
  2. Then go to the menu in Allie using the Settings option at the bottom right
  3. Select "Connected Devices"
  4. Choose "Blood Glucose Meters / CGM"
  5. Then select the "Contour Next One"
  6. This will bring you to Step 1 - Make sure your meter is off and keep it near your mobile device
  7. Tap "Continue" to be brought to Step 2 - Press and hold the center button for 6 seconds until you see the blinking Bluetooth symbol. A blue light should blink when you are in pairing mode.
  8. When you see the blue blinking light on the contour, tap "Continue" in Allie
  9. You should see a notification on your phone asking you to "Pair and Connect". Tap that
    and then confirm you wish to pair
  10. You should see a "Success" page in Allie shortly afterwards. You can tap "Done" to leave the pair ing process

This will return you to the "Connected Devices" screen. You should now see that text indicating your meter is "Connected" or that the "Sync completed just now".


Uploading Blood Glucose Readings to Allie

Now that the Contour is paired to Allie, your future readings will be automatically sent to Allie. They will then be visible for your healthcare provider.

To upload a reading

  1. Make sure that you have Allie open
  2. Insert a strip into the Contour. You should then see this screen indicating it is waiting for you to take a reading:
    If you do not see this screen when inserting a strip, please make sure your Contour is connected per the instructions above
  3. Apply blood/control solution to edge of strip. Try to use a single drop and make sure it is applied to the edge as best you can
    1. If the device beeps and shows you this image, it needs more blood/control solution to take a reading
  4. If the device is starting to take a reading, it will beep and show you a countdown
  5. Your current Blood Glucose will then be displayed on the Contour screen
  6. Next, choose your meal context using the arrows on the contour. Tap the button when you have chosen the appropriate meal context
  7. You'll see the saved reading with a light indicating which range your reading is in
  8. This reading will then be visible in Allie (it may take a few seconds to display) and the "Due" Task will be removed from the timeline. If your completed Tasks are collapsed, press the arrow to expand the section

The values and context in Allie should match the reading from your Guide. You will also see the "Bluetooth" symbol indicating it was sent via Bluetooth. If this is a required task for the day, there will be a check mark next to the reading. 


The measurement will then be available shortly for your healthcare provider to review as needed. You can now turn the Contour off by removing the strip.

If you are only expected to check your glucose once a day, you will not see any more glucose tasks for the day. However, if you take another blood glucose measurement, the new readings will be added to the "Completed" section. There will not be a check-mark for additional readings.

Troubleshooting Issues with the Contour Next One

For general assistance with Allie on Android, please refer to this troubleshooting document.

Read on for specific instructions on using the Contour Next One:

Cannot Take a Blood Glucose Reading

When you add your blood (or the control solution) to a strip that is inserted into the Contour, you should see a screen prompting you to add a small drop of blood to the strip.


In some cases, the amount of blood may be insufficient, in which case you'll see the following:


This indicates you need to add another drop of blood until you see the countdown which confirms the Contour is measuring your glucose levels. If you do not add enough blood within a minute, you'll see an "E1" error message indicating to try again with a new strip.


Additionally, if you see an E2 code when inserting a strip for the first time, this indicates there is an issue with the strip you've used.


Simply try another strip and you should be prompted for a reading.

Not Prompted When Inserting Strip into Contour

If the process appears to have been successful, but when you insert a strip in the Contour you are NOT prompted to take a reading and instead only see the "Bluetooth" symbol pairing appears successful, but you are NOT prompted to take a reading, and only see the "Bluetooth" symbol, please contact Codex Support using this webform. Our staff will follow-up to schedule a troubleshooting session, as this issue can likely be addressed by the following:

  • Unpair the Contour from Allie
  • Install the Contour Diabetes manufacturer application
  • Sign in and pair your device with this application
  • Turn Bluetooth off on your phone
  • Take a Blood Glucose measurement while Bluetooth is turned on
  • Uninstall the Contour Diabetes manufacturer application
  • Turn Bluetooth on for your phone
  • Go back to Allie and see if the device is listed
    • If so, refresh and see if the recent reading is uploaded
  • You can also try taking another reading

Given the complexity of this solution, we recommend contacting Codex Health Support for assistance.
