再发一帖！还是SNIFFMODE求问！

2564的SPPLEDEMO里的SNIFFMODE命令参数到底怎么配？

我写的是SniffMode 1 500 48 30 1000

命令格式：SniffMode  [SerialPortID] [MaxInterval] [MinInterval] [Attempt] [Timeout]

SerialPortID 和Attempt到底是什么？

HCI_Sniff_Mode

 This command places the specified connection into Sniff Mode as per the specified parameters.

Prototype:

int BTPSAPI HCI_Sniff_Mode(unsigned int BluetoothStackID, Word_t Connection_Handle, Word_t Sniff_Max_Interval, Word_t Sniff_Min_Interval, Word_t Sniff_Attempt, Word_t Sniff_Timeout, Byte_t *StatusResult)

Parameters:

 BluetoothStackID1       Unique identifier assigned to this Bluetooth Protocol Stack via a call to BSC_Initialize

 Connection_Handle     Unique identifier for the connection returned in the Connection Complete event associated with the HCI_Create_Connection command.     Sniff_Max_Interval        Maximum time between each sniff period. Values are number of baseband slots (0.625 msec), with a range of 0.625 msec (0x0001)to                                  40.9 sec (0xFFFF).

Sniff_Min_Interval        Minimum time between each sniff period. Values are number of baseband slots (0.625 msec), with a range of 0.625 msec (0x0001) to                                 40.9 sec (0xFFFF).

返回  Invalid Command

sniffmode的使用真的没有什么好的文档，第一次弄全无头绪。我开启了服务后（Open 9）,Server Opened: Server Port 9,Serial Port ID 1,所以我终于找到了这个所谓的Serial port ID ,然后我输入SniffMode 1 500 48 30 5000,在   FindSPPPortIndex 函数里if(SPPContextInfo[i].LocalSerialPortID == SerialPortID)条件终于满足了，但是！这样返回的就是0，SniffMode()里if(((SerialPortIndex = FindSPPPortIndex(LocalSerialPortID)) >= 0) 条件又不满足，又卡住了。。TI的员工们，请来回答一下好吗？

if(((SerialPortIndex = FindSPPPortIndex(LocalSerialPortID)) >= 0) && (SPPContextInfo[SerialPortIndex].Connection_Handle))这个判断条件前半段是满足了，后半段在调试内存观察框了看见值为0，所以不行。按照程序的意思，这个值应该非零，那么该怎么获得非零值呢？
