If you view your Dexcom data on a receiver like the ones pictured above, follow these steps:

1. Connect your Dexcom receiver

  • Connect your Dexcom receiver to your computer via the micro-USB cable.
  • Launch the Tidepool Uploader and log in to your account.
  • Confirm Dexcom (G4, G5 & G6) Receiver is one of your devices. You can change your devices by selecting Choose Devices from the menu under your name.



2. Upload your data

  • Confirm Tidepool Uploader is set to the correct time zone.
  • Click the Upload button to upload your Dexcom data.

Connecting your Dexcom account to Tidepool Web (US Dexcom users only)

If you use your smartphone (iPhone or Android) to receive Dexcom CGM data using the Dexcom app: please follow these instructions to connect your Dexcom account to Tidepool to see your Dexcom CGM data in Tidepool. This feature is only available to Dexcom users with US-based Dexcom accounts.

Uploading Dexcom CGM data from your Tandem insulin pump

If you use your t:slim X2 as your Dexcom receiver, your Dexcom CGM data will upload along with your insulin pump data: please follow these instructions to upload your t:slim X2 to Tidepool. 

Next steps

After the upload is complete, you can upload another device or click "See data" to view your uploaded data.

Troubleshooting

If your Dexcom fails to upload:

  • Please be sure that you have installed the latest version of the Tidepool Uploader.
  • Check that your device is charging when plugged into the cable — if it is not, then you may have a faulty cable or a faulty USB port on your receiver.
  • Unplug the device from the micro-USB cable and plug it back in. Wait for the receiver to confirm it is charging before clicking Upload again.
  • Switch the USB port that the Receiver is attached to on your computer, wait for the receiver to confirm it is charging before clicking Upload again.
  • Try another micro-USB cable. Some micro-USB cables are designed to carry a signal for power only.
  • If you are on a Windows PC, please make sure you have installed the latest Windows updates as this can keep the computer from correctly recognizing the device. 

If you uploaded your data, and see nothing in your Tidepool Account:

  • Refresh your Tidepool Account.
  • If you have only uploaded your Dexcom, please note that this will not show any data in the Basics or Weekly views at this time. Please go to the Daily View or Trends to see your CGM data.
  • Please make sure that you are in the correct time period. The Dexcom Receiver only holds up to ~30 days of data.
