If you encounter a "Connection Error" while attempting to scan your CGM, it's likely due to a proximity issue between the sensor and your phone. This error message typically refers to the NFC (Near Field Communication) connection between your phone and the CGM sensor, and is not related to cellular data or wifi.
First, try scanning the sensor again by simply touching your phone to the CGM where the NFC chip is located. For iPhone users, this is located near the selfie camera, and for Android users it is usually around the center of the back of the device.
If that doesn't work, we recommend trying to scan on Wi-Fi only by turning off your cellular data. If you still can't get a successful scan, try turning your cellular data back on and turning off your Wi-Fi, then attempt to scan again. It's important to note that the CGM requires an internet connection in order to upload your readings into the app.
