 From my understanding of the softdevice API, the maximum packet length is set using sd_ble_opt_set(BLE_GAP_OPT_EXT_LEN, &amp;amp;opt) , but the actual change to the packet length happens through the function sd_ble_gattc_exchange_mtu_request() and sd_ble_gatts_exchange_mtu_reply</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Tue, 28 Mar 2017 20:19:34 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/17173/packet-length-extension-for-l2cap-data-transfer" /><item><title>RE: Packet Length Extension for L2CAP data transfer</title><link>https://devzone.nordicsemi.com/thread/65978?ContentTypeID=1</link><pubDate>Tue, 28 Mar 2017 20:19:34 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:5a3cf740-8c50-487e-ad94-3c2a06cb71f0</guid><dc:creator>jsimmons</dc:creator><description>&lt;p&gt;Hi, Could this response be clarified a bit? It is still not clear to me.&lt;/p&gt;
&lt;p&gt;The language uses seems to imply that the raw l2cap connection packet length is indeed increased once those functions have been called.&lt;/p&gt;
&lt;blockquote&gt;
&lt;p&gt;&amp;quot;you have to go through the functions you have listed&amp;quot;&lt;/p&gt;
&lt;/blockquote&gt;
&lt;p&gt;Is this interpretation accurate? Or did you mean that it is explicitly impossible to receive extended packet length through &lt;em&gt;RAW&lt;/em&gt; l2cap by any means?&lt;/p&gt;
&lt;p&gt;Thank you.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Packet Length Extension for L2CAP data transfer</title><link>https://devzone.nordicsemi.com/thread/65977?ContentTypeID=1</link><pubDate>Thu, 20 Oct 2016 14:42:18 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:49e67a4b-5c82-44c3-8ddc-f090fa12b676</guid><dc:creator>Petter Myhre</dc:creator><description>&lt;p&gt;We do not discuss future plans here, if this is something you are interested in you should contact the regional sales manager for your area, if you don&amp;#39;t know who it is, send me a PM with your location and I&amp;#39;ll let you know.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Packet Length Extension for L2CAP data transfer</title><link>https://devzone.nordicsemi.com/thread/65976?ContentTypeID=1</link><pubDate>Thu, 20 Oct 2016 14:09:19 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:44d497d9-0695-4df9-97c6-d58f0608bfe5</guid><dc:creator>Youssif</dc:creator><description>&lt;p&gt;Thanks.
