DWM1000 Tag with MSP430

Ultra-Wideband
,
#1

I wrote a blinking code over spi. (i wrote same code in stm32). I have a ancher connected to stm. Normally if stm tag transmit data, i read the data from stm tag. But if i transmit same data with msp430, i don’t read the data from stm anchor. My tag code is :

dwt_writetxdata(sizeof(blink_msg), blink_msg, 0);
    dwt_writetxfctrl(sizeof(blink_msg), 0, 0);
    dwt_starttx(DWT_START_TX_IMMEDIATE);

And i read spi data with logic analyzer.

STM tag spi data = 89 01 13 00 80 05 40 16 00 8D 02
MSP tag spi data = 89 01 13 00 88 05 40 00 00 8D 02

What is the reason of difference between these two data and why I can not detect the data I sent over msp from stm.

is there anyone who can say my problem???
