Your Dexcom G7 app uses Bluetooth to connect with your transmitter. You must keep your smartphone’s Bluetooth turned on to get alerts and sensor readings. It is also good practice to delete old Dexcom G7 sensors and/ or Dexcom G6 transmitters from your device’s Bluetooth list.
[Note: Dexcom G7 sensors connect, send data, and disconnect every 5 minutes. The pairing in Bluetooth for your current Dexcom G7 sensor will likely say “not connected” and is expected.]

  2. Find Bluetooth
  3. Turn it on
How to remove old sensors from Bluetooth connections
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.

  2. Find your used sensor in the list of devices
    Tips:
     a. Bluetooth shows all sensors as Not Connected
     b. All Dexcom G7 Dexcom sensor names start with DXCM

How does the Dexcom G7 Apple Widget work?The Dexcom G7 Apple widget lets you see your glucose numbers on your lock screen or home screen without opening the app.

Why is the Dexcom G7 Apple Widget displaying "---" and not my glucose number?
The widget changes for different situations, such as these:
“ ---”: Displays where there's no sensor reading available. The operating system limits the number of times a widget can be updated each day. When the widget hasn't updated as expected, it will show ”---” instead of a sensor reading and there will be a gap in the trend graph.
No Alerts banner and “---”: Displays when there's an alert that prevents you from seeing a sensor reading, such as Signal Loss. There will be a gap in the trend graph.
To open the G7 app, just tap the widget. This will direct you right to the Dexcom G7 App to get your glucose reading when the widget is showing "---".
