I&amp;#39;m currently stumped by a most peculiar issue. 
 Im using two PCA10040 boards (20 cm apart) to send a data stream via the GZLL protocol: DEVICE button pressed -&amp;gt; DEVICE sends two bytes (uint16_t) that pretty much tell the HOST how many bytes</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Tue, 11 Aug 2020 13:51:04 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/64715/nrf-52-pca10040-gzll-host-rx-issue" /><item><title>RE: NRF 52 (PCA10040) GZLL Host Rx Issue</title><link>https://devzone.nordicsemi.com/thread/264100?ContentTypeID=1</link><pubDate>Tue, 11 Aug 2020 13:51:04 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:c1775536-ddb7-4712-8729-0ea616e38547</guid><dc:creator>pauleffect</dc:creator><description>&lt;p&gt;&lt;pre class="ui-code" data-mode="c_cpp"&gt;typedef struct

&lt;p&gt;Apparently it (could have been) was an alignment issue. Doing this seems to work...&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
