# Bluetooth sensors

Configure external Bluetooth sensors on a GPS device in Navixy by MAC address and type, so the platform interprets their values correctly.

Configures external Bluetooth sensors connected to certain device models. These sensors transmit raw data, often just a MAC address and a value, so you map each one here and the Navixy platform interprets it correctly. This block pairs with the platform-side [Sensors and buttons](/docs/user/guide/devices-and-settings/vehicle-sensors.md) block: saving here creates the corresponding sensors there.

## How to configure Bluetooth sensors

{% stepper %}
{% step %}

### Open the block

In **Devices and settings**, select the device, then expand the **Bluetooth sensors** block.
{% endstep %}

{% step %}

### Enter the MAC address

Enter the unique MAC address (the hardware identifier printed on the sensor's label) of the Bluetooth sensor so the platform associates it with the correct device.
{% endstep %}

{% step %}

### Select the sensor type

Choose the sensor type:

* Temperature and humidity sensor
* Tire pressure and temperature sensor
* Panic button
* Hardware key
* Door sensor
* Relay
  {% endstep %}

{% step %}

### Save

Save the configuration. The platform creates the corresponding sensors in the **Sensors and buttons** block.
{% endstep %}
{% endstepper %}

## Availability

Appears on device models that support external Bluetooth sensors.

## Limitations

* Bluetooth sensors often need configuration on the device side too. Channel numbering can differ between the device's configurator and Navixy.

## See also

* [Vehicle sensors](/docs/user/guide/devices-and-settings/vehicle-sensors.md): the platform-side sensors this block feeds.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://navixy.com/docs/user/guide/devices-and-settings/device-specific-controls/external-sensors/bluetooth-sensors.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
