# Elios 1 Tablet not connecting to the remote controller

The GCS is mounted (tablet and controller ON and connected with the USB cable). If the connection status in Elios Cockpit shows the controller blinking, that means you have either a USB cable failure, a tablet’s connector failure or an issue within the Tablet default USB accessory attribution.

**Faulty USB cable**

Try another USB cable and see if it works. If not, it is probably a connectors failure or a software failure.

**Faulty Tablet’s micro USB connector**

Try wiggling the USB plug on the Tablet’s side. If no connection is made, it is probably a software failure.

**Fix the software failure**

1. Disconnect the tablet from the controller and turn off the controller.
2. Go to the application menu and open settings.&#x20;
3. Go to Application > Application manager > cockpit > Set as default > CLEAR DEFAULTS.&#x20;
4. Restart the tablet and wait for it to be fully turned on.
5. Connect the controller to the tablet, then turn on the controller.
6. A dialog box will pop up. Check the case “Use by default for this USB accessory” and tap OK. If instead a list slides up from the bottom side of the screen, tap on “Cockpit”.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://knowledge.flyability.com/aircraft/elios-1/elios-1-troubleshooting/elios-1-tablet-not-connecting-to-the-remote-controller.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
