想要修改连接时间间隔，代码协议栈和例子用的是：
C:\TI\Connectivity\CC256X BT\CC256x STM32 Bluetopia SDK\v4.2.1.0\NoOS\STM3240G-EVAL\Samples\SPPLEDemo
修改时间间隔的地方只在sppledemo.c的建立连接ConnectLEDevice（)函数中找到参数初始化设置
static int ConnectLEDevice(unsigned int BluetoothStackID, BD_ADDR_t BD_ADDR, GAP_LE_Address_Type_t RemoteAddressType ,GAP_LE_Address_Type_t OwnAddressType, Boole
ConnectionParameters.Connection_Interval_Min = 20; //modify by yhc 2017.06.01
ConnectionParameters.Connection_Interval_Max = 200;
ConnectionParameters.Minimum_Connection_Length = 0;
ConnectionParameters.Maximum_Connection_Length = 10000;
ConnectionParameters.Slave_Latency = 0;
ConnectionParameters.Supervision_Timeout = 20000;
我想问的是CC2540中有 GAPRole_SendUpdateParam（）函数发送参数请求的函数，CC2564有没有类似的函数，谢谢！
