Hi Sam, 
I did a quick test here and found no problem finding the retransmit count and interval menu inside the publication setting. 
Could you double check ? and take a screenshot of what you have in Publication setting ?

Hi Hung,               

Thanks for the response.

There is a different naming convention used in latest app.

Could you please provide steps how to navigate to the publication settings in latest app(3.2.4).

Hi Hung,

May i know which android version Nrf Mesh app your using?

I'm not able to find selection for Vendor Model,please go through the screenshot i have attached.

[Hung Bui]

Have you tried to click on the Generic OnOff Server model, for example ? 
I was testing using the Chat example.

Hi again Hung,

Finally i found that settings visible.

Are these features available in IOS Nrf mesh application also??

[Hung Bui]

Yes. it's available on iOS nRF Mesh as well. 

[SAMEER]

Ok.Can you please suggest where can i get details about settings we do for each menu in Nrf Mesh app for both Android/Ios.

Also when we do for Publication settings,the settings are not being saved.

Please provide any links for detailed information regarding app settings.

Hi Sam,

I think it's self explanatory. 
If you want to know more about the term "Retransmit count" and so on, I would suggest to look into the Bluetooth mesh specification for example:

Could you let me know you found this issue on Android or on iOS ? Which SDK you use on the nRF52 ? Which example you tested with and how you tested. 

[SAMEER]

We faced issue in Android app(3.2.4).

We are using nRF5 Mesh SDK, v4.2.0 the mesh peripheral is a relay used for lightning and we call it as CB.

Basically we connect all the CB's to mesh network and later if the switch is pressed the command(cmd) is broadcasting via BLE and after the fist CB reached it will transfer to the other and it goes on to the all the CB's connected in the Mesh.

When we create mesh & try to apply publication settings the values not getting saved.

So if we get any document or link how to use each feature in app it would be great for us.

Hi Sam, 

I don't think the app would read the publication setting or store it on the phone. So, it's better to check it internally on the mesh node to see if it get that configured. When you open it on the app, it's the default value that it would display. 

Could you try to add a log inside handle_config_model_publication_set() at line 1364, something like this: 

__LOG(LOG_SRC_ACCESS, LOG_LEVEL_INFO, " Retrans = %x , interval = %x", publish_retransmit.count,publish_retransmit.interval_steps);

We may be able to check if it's actually got written by the app or not. 

Also please consider to move to the latest nRF5 Mesh SDK (v5.0) or to nRF Connect SDk if possible. 

I have experienced this issue in 2019, but the app supposed to fix this problem a few year back.

Hi Hung,

               What is the actual meaning of Interval and Retransmission Count parameters done in Publication Settings.

As per my understanding Interval means time between messages sent from Tansmitter to Receiver,is my understanding correct?

I dint find any difference when i change the values of Inetrval parameter.

Could you please give more details regarding the parameters Interval and Retransmission count.

Hello Sam, I will be taking over this case for now.

The retransmission interval is the time between the retransmissions. You can find this description of it right after the one on Publish Retransmit Count that Hung sent you in the spec. I would recommend taking a look at the Mesh Spec for these questions, as it does a very good job of explaining the entirety of how Mesh works.

 

Here is an illustration of the difference between the two.
