To resolve connectivity issues with the Carly app following an adapter update, follow these steps methodically:

1. Reboot Your Device
Start by rebooting your smartphone to refresh its system processes, which may resolve temporary connectivity problems.

2. Reinstall the Carly App
Uninstall the Carly app from your device and then reinstall it from the Google Play Store. This step ensures that you have the latest version and also resets any app-specific settings that might be causing issues.

3. Reset Bluetooth Connection
- Navigate to your device's Bluetooth settings and remove any paired Bluetooth devices that might conflict with the adapter.
- Once removed, turn off Bluetooth, wait a few seconds, and then turn it back on.

4. Enable Location Services
Ensure that Location services are enabled on your phone:
- Go to Settings > Location and toggle it on. The app may require location access for proper operation.

5. Reconnect the Adapter
- Plug the Carly adapter into your vehicle's OBD2 port.
- Check that the lights on the adapter indicate it is functioning properly (usually it should be flashing).

6. Connect to Carly Network
- In your phone's Wi-Fi settings, look for the Carly network and connect to it. It’s typically named something like "Carly-XXXX."
- Avoid connecting to any other Wi-Fi network while using the Carly app.

7. Start the Car
Turn on your vehicle's ignition (without starting the engine) to power up the OBD2 system. This often helps in establishing a successful connection with the Carly app.

8. Launch the Carly App
Open the app and attempt to connect with the adapter again.

9. Network Settings Reset
If the connection is still not established, consider resetting your network settings:
- Go to Settings > General Management > Reset > Reset Network Settings. This will remove all saved Wi-Fi networks and Bluetooth pairings.
