# Device

**Device Module 1.7.0 | Manage SDK**

## Usage

To use the Device module, you can import it into your project from the Firebolt SDK:

```
import { Device } from '@firebolt-js/manage-sdk'
```

## Overview

A module for querying about the device and it's capabilities.

## Methods

### listen

To listen to a specific event pass the event name as the first parameter:

```
listen(event: string, callback: (data: any) => void): Promise<number>
```

Parameters:

| Param | Type | Required | Summary |
| --- | --- | --- | --- |
| `event` | `string` | Yes | The event to listen for, see [Events](/docs/170-manage-device#events). |
| *callback* | `function` | Yes | A function that will be invoked when the event occurs. |

Promise resolution:

| Type | Description |
| --- | --- |
| `number` | Listener ID to clear the callback method and stop receiving the event, e.g. `Device.clear(id)` |

Callback parameters:

| Param | Type | Required | Summary |
| --- | --- | --- | --- |
| `data` | `any` | Yes | The event data, which depends on which event is firing, see [Events](/docs/170-manage-device#events). |

To listen to all events from this module pass only a callback, without specifying an event name:

```
listen(callback: (event: string, data: any) => void): Promise<number>
```

Parameters:

| Param | Type | Required | Summary |
| --- | --- | --- | --- |
| *callback* | `function` | Yes | A function that will be invoked when the event occurs. The event data depends on which event is firing, see [Events](/docs/170-manage-device#events). |

Callback parameters:

| Param | Type | Required | Summary |
| --- | --- | --- | --- |
| `event` | `string` | Yes | The event that has occured listen for, see [Events](/docs/170-manage-device#events). |
| `data` | `any` | Yes | The event data, which depends on which event is firing, see [Events](/docs/170-manage-device#events). |

Promise resolution:

| Type | Description |
| --- | --- |
| `number` | Listener ID to clear the callback method and stop receiving the event, e.g. `Device.clear(id)` |

See [Listening for events](/docs/listening-for-events/) for more information and examples.
