https://devzone.nordicsemi.com/f/nordic-q-a/17353/apple-bluetooth-design-guidelinesHi Nordic Forum! Looking for the right configuration for the connection parameters, found different references to this Apple guide . The problem is that in the 3rd condition it say: Interval Min + 20 ms ≤ Interval Max Slave Latency ≤ 4 Thaten-USTelligent Community 13Thu, 27 Oct 2016 09:26:24 GMThttps://devzone.nordicsemi.com/thread/66691?ContentTypeID=1Thu, 27 Oct 2016 09:26:24 GMT137ad170-7792-4731-bb38-c0d22fbe4515:49bf1687-9000-46b2-84ab-7b64c69ae9e7Sigurd<p>The last interpretation is correct. There is nothing that’s called <em>“Interval Max Slave Latency”</em>. It&#39;s just a typo in the pdf document from Apple, where they forgot to add a new line. So the 3rd condition is really</p> <pre><code>Interval Min + 20 ms ≤ Interval Max Slave Latency ≤ 4 </code></pre> <p>If you take a look at this <a href="https://developer.apple.com/library/content/qa/qa1931/_index.html">Apple Guides and Sample Code webpage</a>, you can see that the typo is not there, and the last <em>interpretation</em> is listed.</p><div style="clear:both;"></div>
