I suggest that you take a look at the Publish Retransmit Count definition in the latest version of the Spec. (v1.0.1). The "original message is received" part is removed, and it should be less confusing.

So, this is not related to relay-nodes.

It's about the Access model publication, and you can find the use of it in access.c: line 1256, inside access_model_publish().

We check if m_model_pool[handle].model_info.publication_retransmit.count > 0 and the call to access_publish_retransmission_message_add() i made.

[quote user=""]Furthermore, we could not find any clear relation between the value set and the number of messages sent by the client node.[/quote]

I don't understand what you mean by this. Are you not seeing the number of retransmissions to match the "Retransmit Count"?

Joakim

Thank you for your answers.

Since to our understanding the "Network transmit count" is not the same as the " Publish Retransmit Count", then only the "Publish Restransmit Count" can be set from the Android application. But this is somehow related to the other questions and also to the implementation of the sdk, for which answers are still expected.

Got some feedback from our developers.

Question 2: Yes, they mean the same, however the latest app to be released will have the names inline.

Question 3. It does set the configuration to the node, and it should work. You need to verify this on the node side.

Question 4. This should work. Could you elaborate on why you believe that "it seems not possible".?

Best regards,
Joakim

Hello Joakim,

Thank you for your answer. Waiting for answer to the other questions.

It is still not clear to me in which case a message can be retransmitted if it is not relaying a message (Relay node) or acting as a Proxy. Could you be more specific on this ?

And it is not clear to me why a message sent by the switch client is using the Publish Retransmit Count for determining in a way or another the number of times that the message must be sent by the node (as original messages).

Best regards,

Serge

Hi.

[quote user=""]- we understand the Publish Retransmit Count (4.2.2.6) to be the number of times a relaying node will retransmit a message after it receives the original message.[/quote]

The Publish Retransmit Count state is the number of times that a message published by a model will be retransmitted after the original message is received. But not specific to a relay node.

Network transmit count is similar but it is how many times a node is sending a message.

[quote user=""] we understand the Publish Period (4.2.2.2) to be the period (interval) at which status messages are published by a node (no need for a state change).[/quote]

That sounds correct.

For question 2-4, I'll forward these to our nRF Mesh mobile app developers and get back to you.

Best regards,
Joakim
