How do you remove old sensors from my device’s Bluetooth list?
Before inserting a new sensor, remove old sensors from your phone's list of Bluetooth connections.
There may be more than one sensor listed because your phone saves each sensor as a new device in the Bluetooth connections list.
Apple
- On your phone, go to Phone Settings > Bluetooth
- Find a used sensor in My Devices list. Dexcom G7 sensor names start with DXCM.
- Tap i to see details about this sensor.
- Tap Forget This Device.
Android
- On your phone, go to Phone Settings > Connections > Bluetooth
- Find your used sensors in the list of paired devices. Dexcom G7 sensor names start with DXCM.
- Tap Settings to see details about the connection.
- Remove your used sensor from the list.
Remove while using sensor
To remove old sensors from the Bluetooth connections list while you are wearing one, follow the above steps and keep these tips in mind:
- All Dexcom sensors are listed as not connected, even the current one. The current sensor’s status changes to connected during the few seconds every 5 minutes when it’s sending your sensor reading to your phone. If you watch the list for up to 5 minutes, you’ll see which sensor is the current one.
- Don’t worry if you remove the current sensor. Within 5 minutes, the sensor will send your next sensor reading to your phone and the sensor will reappear in the Bluetooth connections list. (If you use an iPhone, it will prompt you to re-pair the sensor — no pairing code needed. Android phones do this automatically.)
