.sp
.BI "extern char* kdk_bluetooth_get_link_policy(int "id ");"
.sp
Link with \fI\-lkybluetooth\fP.
.SH "Detailed Description"
The main function of the interface is to obtain the link policy of Bluetooth.
.PP
The argument
.I id
is the device ID of Bluetooth.
.SH "RETURN VALUE"
On success, returns the Bluetooth link policy of type char*; The returned string needs to be released by
.I free
.PP
On error, return
.BR NULL.
