Troubleshooting common Dexcom G4 receiver uploading issues

If your data fails to upload from your Dexcom G4 receiver, please try the following:

  • Please be sure that you have installed the latest version of the Tidepool Uploader.
  • Check that your receiver 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 receiver 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, please try the following:
  • Refresh your Tidepool account with the refresh button in the lower left corner of Tidepool Web.
  • 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.
