⛔ Troubleshooting → If you can’t upload data successfully, there are 2 possible reasons:
- Bluetooth or Internet are not enabled.
→ Please ensure Bluetooth and internet features on your phone are active.
- Bluetooth Signal Interference
→ As Bluetooth connection is used, only 1 CoTag device can be uploaded at the same time within the same space (10 meters in an open area, or within a single room) to avoid signal interference. If you have multiple devices, please upload them sequentially.
