https://devzone.nordicsemi.com/f/nordic-q-a/92973/ttl-behaviour-with-number-of-devices-in-a-ble-meshHi team, If the TTL count is 100 but the number of devices in the network is 10. Will the device routing table in BLE mesh SDK understand that the message has been already relayed by this node and it should not be relayed further (after say 10 hopsen-USTelligent Community 13Wed, 19 Oct 2022 06:10:29 GMThttps://devzone.nordicsemi.com/thread/391324?ContentTypeID=1Wed, 19 Oct 2022 06:10:29 GMT137ad170-7792-4731-bb38-c0d22fbe4515:caa5de7f-e092-4722-bf46-d6ee2a131f91Simonr<p>Hi</p> <p>I think my colleague Terje explains/clarifies <a href="https://devzone.nordicsemi.com/f/nordic-q-a/72634/mesh-ttl-clarification">how a Mesh network handles packets and TTL values in this ticket</a>. You should not have anything to worry about, since a node will only increase the TTL the first time it receives a package.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
