 Of late, I&amp;#39;ve been evaluating Zephyr in its support of the nrf5340. I&amp;#39;ve come across several deficiencies that need to be addressed: 
 1. All callbacks (for the most part), lack the ability to have associated &amp;quot;user data&amp;quot; or context information.</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Mon, 22 Nov 2021 16:58:41 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/81976/critical-review-of-several-zephyr-features" /><item><title>RE: Critical review of several Zephyr features...</title><link>https://devzone.nordicsemi.com/thread/340177?ContentTypeID=1</link><pubDate>Mon, 22 Nov 2021 16:58:41 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:f1fbbb64-0d5b-4ab3-8004-b5cce43be1b8</guid><dc:creator>&amp;#216;yvind</dc:creator><description>&lt;p&gt;Excellent, this is exactly what we need from users.

The nRF Connect SDK&amp;nbsp;integrates&amp;nbsp;the Zephyr OS and its features, such as callbacks and net_buf networking. I do recommend reaching out to the &lt;a href="https://discord.com/invite/Ck7jw53nU2"&gt;Zephyr community through their Discord channel&lt;/a&gt;.&lt;br /&gt;&lt;br /&gt;Kind regards,&lt;br /&gt;Øyvind&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
