SPI inconsistent read

[Robert]

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.

May be problem with the clock speed. If the sensor can't operate at high speed and the clock in the mater is high then you get the problem in reading. try to check with the low frequency as possible.

Hi Robert, SPI in nordic chip is known to work correctly (I have not seen any issues) Are you using SDK SPI drivers or are you using your own SPI code? Are you sure you have configured the SPI to right mode?
