&lt;p&gt;This sounds like an SPI signalling issue.&amp;nbsp;&lt;/p&gt;
&lt;p&gt;A sure way to reset the configuration registers is to power cycle the nRF24 itself.&lt;/p&gt;
&lt;p&gt;Have you tried to read out the state of the configuration registers after a power reset to make sure the read function is working properly?&lt;/p&gt;
&lt;p&gt;Once the read function is confirmed to work you should try to&amp;nbsp;write to one of the registers, and read it back afterwards to ensure that the write also worked.&amp;nbsp;&lt;/p&gt;
&lt;p&gt;Best regards&lt;br /&gt;Torbjørn&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
