Communicate TRX moduls and sensor

Hi guys,
i want to send Data of sensor from a CC1101 to another CC1101. I could 
send and receive Infos between TRX Moduls with SPI interface. I used 
SHT31 and i can measure Tempratur and Humidity. Now i must send data 
from sensor to my one CC1101 as Transmiter than from Transmiter to 
Receiver(another CC1101).
SHT31 works with I2C and CC101 works with SPI, my Microcontroller ist 
STM32F446re .
I have  got this Error:

1) Failed to execute MI command:
-var-create - * spiRX
Error message from debugger back end:
-var-create: unable to create variable object

I hope you can help me.
Have a nice day.
