 I&amp;#39;ve just started working with the nRF24L01+, and I&amp;#39;ve come across some issues when attempting to do an initial read from the datapipe 0 RX address. 
 After reset, setting up SPI, etc, I try to do a test clock in of register 0x0A (RX_ADDR_P0</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Fri, 02 Oct 2015 08:22:46 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/9522/reading-datapipe-0-reset-address" /><item><title>RE: Reading Datapipe 0 reset address</title><link>https://devzone.nordicsemi.com/thread/35174?ContentTypeID=1</link><pubDate>Fri, 02 Oct 2015 08:22:46 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:7e1b44b1-3f42-4655-92c9-1acab4bd2364</guid><dc:creator>H&amp;#229;kon Alseth</dc:creator><description>&lt;p&gt;Hi,&lt;/p&gt;
&lt;p&gt;Given the reset value of &amp;#39;0x02&amp;#39; that you&amp;#39;re reading out, it indicates that you&amp;#39;re reading reguster RF_CH (0x05) instead of register 0x0a.&lt;/p&gt;
&lt;p&gt;If this is correct, it indicates that you&amp;#39;re using the wrong SPI mode:

&lt;p&gt;Could you try setting your host controller SPI mode into mode &amp;#39;1&amp;#39;, as according to this page?
