https://devzone.nordicsemi.com/f/nordic-q-a/27449/acknowledged-message-re-transmit-timeHi, I&#39;m currently investigating the Bluetooth mesh using the SDK for mesh alpha 0.10.0, I was wondering about the limitations on the re-transmission of messages. The current equation for calculating the re-transmit of messages is as follows, uint32_ten-USTelligent Community 13Wed, 22 Nov 2017 12:19:11 GMThttps://devzone.nordicsemi.com/thread/108412?ContentTypeID=1Wed, 22 Nov 2017 12:19:11 GMT137ad170-7792-4731-bb38-c0d22fbe4515:54fa0973-1913-46c8-95aa-6861fe617cafrichardjallen<p>Thanks for the answer,</p> <p>Richard</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/108411?ContentTypeID=1Wed, 22 Nov 2017 12:00:01 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2674cb86-ba15-4ddf-b245-585dddabf005ketil<p>Hi,</p> <p>The Bluetooth Mesh specification does not put a limit on the re-transmission of messages and you are free to change all of the values to suit your application*. The default values in the SDK are likely to work well in most scenarios.</p> <p>*<a href="https://www.bluetooth.com/specifications/mesh-specifications">Mesh Profile Specification 1.0</a> Section 3.7.5.2 Acknowledged message</p> <p>I recommend you ask Bluetooth SIG regarding the EU directive.</p> <p>Ketil</p><div style="clear:both;"></div>
