SPI inconsistent read

Question

Hello ! When I make a read with the SPI from a sensor's register the data sometimes comes correct and most of the time wrong. I tested the read operation with an Arduino and it always comes correct. Why is that problem ? I am using NRF51822 with s130, softdevice enabled.

Thank you for your answer ! The problem was the breadboard I was using :) I changed it and it works as expected without making any modifications to the code.
