我从网站上下载的CC2564的基于MSP430的协议栈，编译用IAR编译其中的SPPLedDemo，提示link错误Error[e46]: Undefined external "HCI_Send_Raw_Command" referred in EHCILL ( C:\TI\Connectivity\CC256X BT\CC256x MSP430 Bluetopia SDK\v1.3\
CC256x+MSP430_Applications\Source\MSP430_Experimentor\Samples\SPPLEDemo\Projects\IAR\Debug_-_MSP430F5438A_Exp\Obj\EHCILL.r43 )
但是我已经把C:\TI\Connectivity\CC256X BT\CC256x MSP430 Bluetopia SDK\v1.3\CC256x+MSP430_Applications\Source\MSP430_Experimentor\Bluetopia\lib\IAR加入了link的路径，很奇怪，求解。
