I am working on STEVAL-MKI160V1 board which has LSM6DS3 sensor. I want to interface board to AARDVARK I2C/SPI adapter using which I can generate I2C/SPI signals to the sensor. I connected sensor board to adapter, using SPI serial protocol, which gives 00 when I read WHO_AM_I register. If I interchange MISO and MOSI connections, it gives FF to the same register. What does these output values try to tell me. What should I understand? can any one help me. I could succeed reading WHO_AM_I register by using I2C.
