I try to run example Light Switch Demo. 
 I use: Mesh SDK v.2.2.0. NRF SDK v 15.0.0. Softdevice: s132_nrf52_6.0.0. 
 I see that relayed messages have maximum TTL = 4, when i send with initial value 10. 
 I have 8 boards. Boards are placed in line</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Wed, 21 Nov 2018 15:00:40 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/40702/light-switch-demo-relaying-messages-relayed-messages-ttl-limited-to-4" /><item><title>RE: Light Switch Demo.

&lt;p&gt;Could you check the value of ACCESS_DEFAULT_TTL,&amp;nbsp;TRANSPORT_SAR_SEGACK_TTL_DEFAULT and&amp;nbsp;NRF_MESH_TTL_MAX in your code?&amp;nbsp;&lt;/p&gt;
&lt;p&gt;TTL = 4 when you have initial TTL = 10 meaning it went through 6 hops , this doesn&amp;#39;t make much sense in your setup.&amp;nbsp;&lt;/p&gt;
&lt;p&gt;And could you verify those message with TTL = 4 actually are valid message ? A packet that already forwarded should not be forwarded again.&amp;nbsp;&lt;/p&gt;
&lt;p&gt;If you set your original message to TTL = 6 and then 3 for example, what would be the result ?&amp;nbsp;&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
