.SH NAME
kdk_bluetooth_get_dev_version - 获取蓝牙的设备id
.SH SYNOPSIS
.nf
.B #include <libkybluetooth.h>
.sp
.BI "extern char* kdk_bluetooth_get_dev_version(int "num ");"
.sp
Link with \fI\-lkybluetooth\fP.
.SH "Detailed Description"
The main function of the interface is to obtain the device version of Bluetooth.
.PP
The argument
.I num
is the number of Bluetooth devices, starting from 0, 0 represents 1, and so on.
.SH "RETURN VALUE"
On success, returns the device Bluetooth version of type char*; The returned string needs to be released by
.I free
.PP
On error, return
.BR NULL.
