Device Bluetooth
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) The pairing in Bluetooth for your current Dexcom G7 sensor will say 'not connected'. That's ok because it only connects once every 5 minutes to send your sensor reading.
How to turn Bluetooth on
  • Go to Settings
  • Find Bluetooth
  • Turn it on
How to remove an old sensor from your smartphone's Bluetooth connections
  • Go to Phone Settings > Bluetooth
  • Find your used sensor in the list of paired devices Tips: Bluetooth shows all sensors as Not Connected. All Dexcom G7 sensor names start with DXCM
  • Tap to see details about the connection
