&lt;p&gt;&lt;/p&gt;
&lt;p&gt;I filed an incident with Apple five weeks ago but have not heard anything as yet.&amp;nbsp; Have you reviewed the attached sniffer capture that I included?&amp;nbsp; I have also repeated this test after modifying the MTU request size to 185, to remove MTU size from the negotiation.&amp;nbsp; I am still seeing the same behavior minus central&amp;#39;s response to the MTU size request.&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;I guess I am asking for confirmation of my assessment of the problem and whether Nordic has a vested interest in working with the Apple iPhone SE platform.&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;Kind regards,&lt;/p&gt;
