I recently bought a X-NUCLEO-IDB04A1 and wanted to use it with Arduino. How do I go about it ? Please help me out.

My aim is to collect the sensor data from 

http://www.st.com/en/ecosystems/x-nucleo-iks01a1.html

 and send it to Arduino pins and transmit the data via 

X-NUCLEO-IDB04A1 to another Arduino microcontrollers. I need help to interface X-NUCLEO-IDB04A1 with Arduino.

Be careful about IO levels: if you are using Arduino UNO or similar board at 5V, you will need to use level shifters as the BlueNRG chip is not 5V tolerant:

Thanks David. I am okay with the voltage values.

I assume that the communication between X-NUCLEO-IDB04A1 and Arduino is SPI.  I actually want to know how to send data from Arduino to X-NUCLEO-IDB04A1.

Please help me.
