 Is there a way to not be constrained by this limitation. I&amp;#39;ve seen some posts about Zephyr Native TLS. It seems it is an option for the Serial LTE Modem (SLM) application</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Wed, 28 Aug 2024 11:55:40 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/114235/tls-2k-packet-limitation" /><item><title>RE: TLS 2K packet limitation</title><link>https://devzone.nordicsemi.com/thread/500195?ContentTypeID=1</link><pubDate>Wed, 28 Aug 2024 11:55:40 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:ee201ba1-5aca-4f5d-8b95-5ad5900e7aff</guid><dc:creator>Hakon</dc:creator><description>&lt;p&gt;Hello,&lt;/p&gt;
[quote user=""]Is there a way to not be constrained by this limitation.[/quote]
&lt;p&gt;Yes. You need to use &lt;a href="https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/samples/net/https_client/README.html#using_mbed_tls_and_tf-m_on_nrf91_series_dks"&gt;Mbed TLS stack&lt;/a&gt;. The modem lib can&amp;#39;t handle anything above 2k.&lt;/p&gt;
[quote user=""]Is it possible to enable this in a custom nRF9160 application?[/quote]
&lt;p&gt;I believe&amp;nbsp; that should be possible yes.&lt;/p&gt;
[quote user=""]Are there any downsides in doing so?[/quote]
&lt;p&gt;Probably. You should read the documentation. I believe there are certain features like TLS session resumption that are not supported with Mbed TLS.&lt;/p&gt;
[quote user=""]Would I still be able to use other nRF SDK Connect libraries/feature like&amp;nbsp;the FOTA library and REST client?[/quote]
&lt;p&gt;FOTA should be possible. I&amp;#39;m not sure about REST client, but I don&amp;#39;t see why that would not work.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
