https://devzone.nordicsemi.com/f/nordic-q-a/479/spi-communication-is-unreliableHi, I am using the SPI ports (0 or 1) to communicate with a peripheral chip, and the operation is undeterministic. For test, I put the SPI code to read the peripheral family ID in a loop, where if the read is correct I light an LED, and if the readen-USTelligent Community 13Thu, 10 Apr 2014 13:28:15 GMThttps://devzone.nordicsemi.com/thread/2507?ContentTypeID=1Thu, 10 Apr 2014 13:28:15 GMT137ad170-7792-4731-bb38-c0d22fbe4515:96db1233-dfab-40bf-bd14-6f0018ef4b53Asbj&#248;rn<p>Was this issue resolved?

Long wires and breadboards, in combination with high SPI frequency, tend to give a higher bit-error-rate.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/2505?ContentTypeID=1Tue, 17 Sep 2013 15:57:47 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ee2cecd3-037c-4db0-8bed-f2f81aa67c2fMartijn<p>Please provide Some code.</p><div style="clear:both;"></div>
