# kdk\_bluetooth\_get\_dev\_version(3)

获取蓝牙的设备id

## NAME

kdk\_bluetooth\_get\_dev\_version - 获取蓝牙的设备id

## SYNOPSIS

```
#include <libkybluetooth.h>

extern char* kdk_bluetooth_get_dev_version(int num);

Link with -lkybluetooth.
```

## Detailed Description

The main function of the interface is to obtain the device version of Bluetooth.

The argument *num* is the number of Bluetooth devices, starting from 0, 0 represents 1, and so on.

## RETURN VALUE

On success, returns the device Bluetooth version of type char\*; The returned string needs to be released by *free*

On error, return **NULL.**

## EXAMPLES

```
#include "libkybluetooth.h"
#include <stdio.h>
#include <stdlib.h>

    char *scomtu = " ";
    char *alcmtu = " ";
    char *packettype = " ";
    char *features = " ";
    char *bus = " ";
    int **id = kdk_bluetooth_get_device_id();

        printf("scomtu: %s0, scomtu);
        alcmtu = kdk_bluetooth_get_alcmtu(id[i]);
        printf("alcmtu: %s0, alcmtu);
        packettype = kdk_bluetooth_get_packettype(id[i]);
        printf("packettype: %s0, packettype);
        features = kdk_bluetooth_get_features(id[i]);
        printf("features: %s0, features);
        bus = kdk_bluetooth_get_bus(id[i]);
        printf("bus: %s0, bus);
        i++;
    }while(id[i]);
    return 0;
