      • mLab information - both items
      • API_SECRET - remember this item must be at least 12 characters long
      • Make sure the type for all the above is 'Custom'
  • Deploy your site using the Github repository

Nightscout Setup Notes

• Please complete all of the steps listed above

• You do not need to enable the Medtronic Connect plugin

Required Hardware

Android device

This must have the following minimum features

• Android 4.0.3 or above
• USB OTG (On-The-Go) capability
  • Note - this is essential and is sometimes difficult information to track down
  • If you want to check whether a device you already own supports USB OTG you can try this app
    • OTG Troubleshooter

See this list of user tested [Compatible Android devices and firmware](Compatible Android devices and firmware)

USB OTG cable

This needs to be Micro-USB Male to USB A Female, and is used to connect the CNL meter to the Android device.

• e.g. https://www.amazon.co.uk/StarTech-com-5in-Micro-Host-Adapter/dp/B00B4GGW5Q)

Contour Next Link 2.4 BG meter

It is strongly recommended to use a spare CNL meter for uploading data from your 640G pump - do not use your main BG meter

Medtronic 640G insulin pump

Your usual pump

Next steps

640G and CNL preparation

1. Ensure that the batteries are in a good state of charge on all the devices
2. On your pump check that the time is set correctly

• Glucose readings with timestamps from the future will cause problems for your Nightscout website!

1. The pump must have been registered with the European CareLink website
2. The CNL meter and the pump must have been paired / 'connected' with each other
3. The CNL meter must also have been registered with the European CareLink website, i.e. it must have been used for at least one successful upload of pump data (Upload > Select Device = MiniMed pump)
4. Although the 640gAndroidUploader only reads status information via the CNL, to help ensure safety it is strongly recommended that you disable the remote bolus feature:
5. Go to the Remote Bolus screen on the 640G: Menu > Utilities > Remote Bolus
6. Select Remote Bolus to turn the feature off
7. Select Save
