https://devzone.nordicsemi.com/f/nordic-q-a/14608/spi-clock-problemHello, I want to use SPI between one nRF51-DK (using SD130 v 2 and SDK11) and another board. I am supplying the nRF with 2.3 V and initializing the BLE and the SPI. I can connect via BLE to other nRF but I can&#39;t send or receive data from the otheren-USTelligent Community 13Tue, 21 Jun 2016 09:08:50 GMThttps://devzone.nordicsemi.com/thread/55752?ContentTypeID=1Tue, 21 Jun 2016 09:08:50 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a4eb96dc-443d-468b-bb17-3e4546cb18c1Jorge<p>On the beginning the problem was that the CS pin wasn&#39;t being changed. But after this I discovered that one prob on my oscilloscope is somewhat defected, because sometimes it displays the correct clock, and others just lower the signal (if I change the probes it is easy to see the differences). Sorry for the post.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/55751?ContentTypeID=1Tue, 21 Jun 2016 08:48:10 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f5b2c58a-5031-40cc-9b90-0a6ebf3de0caFormerMember<p>First, could you try to toggle the clock pin without anything connected to it?</p><div style="clear:both;"></div>
