I have the same setup here, nRF51 master, nRF52 slave, SDK 12.2 and it works fine on my end. Do ensure that all your pins are correctly connected. nRF52DK: SCK=P0.03, MOSI=P0.04, MISO=P0.28, CS=P0.29, and for nRF51DK: SCK=P0.01, MOSI=P0.02, MISO=P0.03 and SS/CS=P0.04.</p><div style="clear:both;"></div>
