# Bluetooth and Pairing Issues

#### Why is Bluetooth pairing taking so long? Why didn’t I get a PIN request on my phone?

Bluetooth pairing usually takes about 10 to 15 seconds. If it takes more than 60 seconds or an error message appears on the screen of the device, the pairing process likely has crashed.

Access to the device’s location information is a general requirement from Android operating system developers for Bluetooth Low Energy applications to work correctly. [**Read more»**](https://developer.android.com/about/versions/marshmallow/android-6.0-changes#behavior-hardware-id)\

Try to restart your phone, reopen the app and repeat the pairing process. See this topic: [How to Pair with the Aranet Home app](/aranet4/aranet4-home/aranet-home-app/how-to-pair-with-the-aranet-home-app.md). The topic shows the pairing process, which is the same for all of the devices.

#### What would be the first things to try if the Aranet device is not pairing to the Aranet Home application on a mobile device?

Please first try:

1. Take out the batteries of the Aranet device.
2. Set jumper switch in the battery compartment for Bluetooth service in OFF (down) position, then back to ON (Up) position;
3. If you have the Aranet4 or Aranet2 Home device (Not Pro), then also make sure the 4th switch is in the OFF (down) position.
4. Put batteries in the correct polarisation again inside the Aranet (both batteries in the same direction with the + pole on the left side);
5. Uninstall the Aranet Home app completely and delete/forget the paired Aranet device from Bluetooth connected devices on the mobile device.
6. Restart the mobile device.
7.  Install the application again and pair the Aranet device to the mobile device, not via the Bluetooth devices menu, but only via the Aranet Home application.

## 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://help.aranet.com/aranet4/aranet4-home/aranet-home-app/how-to-pair-with-the-aranet-home-app/bluetooth-and-pairing-issues.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.
