3.     Troubleshooting

If your Dexcom fails to upload:

  • 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 Account:

  • Click ‘Refresh’ in the ‘View Current Data’ page or request a new recommendation.
  • Please make sure that you are in the correct time period. The Dexcom Receiver only holds up to ~30 days of data.
  • The last 3 hours from time of data upload will not appear.
