 I&amp;#39;m testing nrf52820 longrange speed, but it&amp;#39;s faster than my calculations. Will it automatically turn on the fec? 
 This is my config below.

&lt;p&gt;That means that master is not sending anything during that time. If that period is less than supeprvision timeout and the obeys slave latency, then master is allowed to send packets with that delay. You need to find out why master is delaying that packet transfer that much (assuming that nRF chip is slave here)&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: How to open longrange fec function?</title><link>https://devzone.nordicsemi.com/thread/361384?ContentTypeID=1</link><pubDate>Mon, 04 Apr 2022 05:09:07 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:fda14b7f-7850-4af4-8085-cff26508e164</guid><dc:creator>Август</dc:creator><description>&lt;p&gt;Hi&amp;nbsp;&lt;/p&gt;
&lt;p&gt;Thank you for your response,In the packets I grabbed, I don&amp;#39;t see the extra bytes.&lt;/p&gt;
&lt;p&gt;When I send a packet, mtu=247 will be followed by such a packet, what is this?&lt;/p&gt;

Based on your connection interval, Is that what you are seeing?&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: How to open longrange fec function?</title><link>https://devzone.nordicsemi.com/thread/360403?ContentTypeID=1</link><pubDate>Tue, 29 Mar 2022 01:05:32 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:0a94d222-5555-4e30-a150-1988cd8b28b2</guid><dc:creator>Август</dc:creator><description>&lt;p&gt;Thank you It&amp;#39;s ok.&lt;/p&gt;
&lt;p&gt;I found another problem, when I send a packet mtu=247 will be followed by such a packet. I didn&amp;#39;t find it in Core_v5.0.pdf&lt;/p&gt;
