There are several reasons why your Sibionics G3 sensor may stop transmitting data:
Sensor lifespan has ended — The Sibionics G3 lasts 14 days. If your sensor has reached the end of its life, you'll need to apply a new one to continue receiving glucose readings.
Sensor was removed or dislodged — If the sensor has been knocked off, loosened, or detached, it will stop transmitting data.
Bluetooth connection dropped — The Sibionics G3 transmits data via Bluetooth. If the connection is interrupted, data will stop flowing to Vively.
Sibionics app not running — Data flows from your sensor through the Sibionics app to Vively. If the Sibionics app isn't active or your account isn't connected, data won't reach Vively.
Exposure to extreme temperatures — If your sensor has been in very hot (e.g., sauna) or very cold (e.g., ice bath) environments, it may temporarily stop working.
Electromagnetic interference — Being near strong electrical sources such as speakers, medical devices, or large power sources can cause data transmission issues.
How to fix the issue
✅ If your sensor hasn't reached 14 days:
Open the Sibionics app first, then open the Vively app — this restores the data flow if the Bluetooth connection has dropped.
Check Bluetooth is enabled on your phone and that your phone is within range of the sensor.
Try toggling Bluetooth off and back on, then reopen the Sibionics app followed by the Vively app.
Restart your phone — a simple reboot can often resolve connectivity issues.
Move to a stable temperature — if your sensor was exposed to extreme heat or cold, allow it to return to room temperature and try again.
Move away from electromagnetic interference — step away from devices that may be disrupting transmission.
Wait a few minutes and check again — if the issue is temporary, the sensor may resume transmitting on its own.
❌ If your sensor has reached 14 days:
The Sibionics G3 sensor automatically stops working after 14 days. Apply a new sensor to continue receiving glucose readings.
When to contact support
If your sensor still isn't transmitting after trying the steps above, it may be faulty.
📩 Contact Vively Support at contact@vively.com.au and we'll arrange a replacement if there is an inherent fault with the device.
