Mesh SDK 3.1.0 retransmit count error

Hi Hung,

I checked my retransmission count it is set correctly now.

For me after client correctly transmitting payload for first time, the retry messages(when status is not received) goes as garbage values because the payload buffer is cleared somehow I think.

Anyways I will create a new case after some more dig.

@Aniket: Are you sure this is related to the retransmission count ? Do you have the correct number of retransmission ?

Please create a new case with more description on what you are doing.

Hi Hung,

I used one of my vendor model to test this. I observed that if I transmit buffer of length till 75 bytes then model was not retransmitting message with garbage data. But if i transmit like 80 bytes of data then it sends the message again with garbage data.

I am using Android app.

Hi Aniket,

We have released the fix version. Do you still have the same issue ? It was iOS or Android app ?

Hi Hung,

Is this issue fixed in the latest app release? You mentioned that it has been fixed in the app. If not released is the fix available on any of the branch on the github?

I have checked, the issue was not on the Mesh SDK/stack but on the Android/iOS app. It has been fixed in the app but the new version is not released yet. So the issue is still exist.

Hi,

is this issue resolved on new mesh sdk 3.2.0 ?

Looking to the changelog I do not see any reference to this issue.

The iOS library is known for bugs. You should try the Android version as well.

By looking at the code https://github.com/NordicSemiconductor/IOS-nRF-Mesh-Library/blob/58e5ed76a8fda9972e31cfeec81543ae27ff5646/nRFMeshProvision/Classes/MeshPDUs/AccessMessages/ModelPublicationSetMessage.swift#L32

and comparing with the standard hints that the bits aren't placed where they should.

I have reported the bug internally but unfortunately, I don't know when a new version with bugfix for this will be ready, at least in the next 1-2 months.

Here is a log of the above issues:

<t: 117902>, main.c, 695, OnOff server: 0x0001, Present OnOff: 1

<t: 121179>, main.c, 695, OnOff server: 0x0001, Present OnOff: 0

<t: 124455>, main.c, 695, OnOff server: 0x0001, Present OnOff: 220

<t: 127733>, main.c, 695, OnOff server: 0x0001, Present OnOff: 161

The repetitions count was set to 2 and we received 4 repetitions and as you can see the content of the onoff value changes on every repetition.

The right value is only the first (one).

Please verify.
