interface msp430 with cc3000wifi TI need external components

Hello all, I am using msp430f249 MCU to interface with cc3000mod TI and I had a problem when initiating start cc3000 via SPI. when I sent first write command to start cc3000 wifi , but cc3000 response wrong data. here is cc3000 document: : http://processors.wiki.ti.com/index.php/CC3000_Serial_Port_Interface_(SPI) from msp430 to cc3000 command: 01 00 05 00 00 01 00 40 01 00 . I sent right command on TXbuffer register. from cc3000 to msp430 command: I received : {02}{00}{FF}{00}û{00}{00}{00}{00}û (wrong received data) instead of 02 00 00 00 05 04 00 40 01 00 (right data). Only first two bytes are true 0x02,0x00 and otherwise is false. there are 5 connected pins, SPI_CS,SPI_Din,SPI_Dout, SPI_CLK, SPI_INT. Personally, I think that signals did not completely transmit to cc3000, so it didn't response right data. I pay attention to 2 pins SPI_CLK and SPI_Dout because it transmits data to cc3000. I get feedback someone say that it didn't match impedance but I don't know how much impedance or capacitor, resistor, inductor should add?. I am not electrical profession, so it is difficult to solve it. Someone can help cope with this situation, hopely? Thank you so much regards Tuong

someone help solve this one?

Why?
