Hi joe_su,

If that is the only thing that has been changed compared to when you last had the issue, then yes, I think so.

It could be the issue fixed here: https://github.com/NordicSemiconductor/Android-nRF-Mesh-Library/commit/c9376ff59631d5e1e70319abab81721f37332b03.

Best regards,

Hi Hieu,

[quote userid="9456" url="~/f/nordic-q-a/113549/bluetooth-mesh-light-example-connection-problem/497078"]You can just create an App Key from in the last tab and assign it to the node.[/quote]

That's great. After creating the app key and adding it, I can control the device normally.
So is the cause of this problem due to the nRF Mesh app version?

Hieu,

[quote userid="9456" url="~/f/nordic-q-a/113549/bluetooth-mesh-light-example-connection-problem/497043"]Mine is 3.3.3. You could try to update.[/quote]

I installed version 3.3.3. After adding the device, Elements can be recognized; but because there is no app key, I cannot control the device. You can check the video I recorded for details.

I still can't run the demo normally. I don't know where the problem is. I need your help. Thank you very much.

Best regards,

joe_su,

[quote user="joe_su"]3. Hypothesis 1: Is there a problem with the SDK version? The download address of my SDK version v2.7.0 is lierda.feishu.cn/.../UH46wkIQSiVPoUkWaaQc9YrcnYb[/quote]

It could be. Rather than download it from that link, why did you not use one of the methods described in our documentation?

[quote user="joe_su"]4. Hypothesis 2: Are the app versions tested consistent?[/quote]

Mine is 3.3.3. You could try to update.

[quote user="joe_su"]You said last time that the example runs normally, can you please help me record a video of the device successfully adding the app? I will compare the adding process here[/quote]

Let me get to this tomorrow.

Hi Hieu,

1. I tried to use the command: nrfjprog --recover to erase the chip
2. After re-burning the firmware in west flash, I still had the same problem when adding it using nRF Mesh app, which is the same as the problem described above

3. Hypothesis 1: Is there a problem with the SDK version? The download address of my SDK version v2.7.0 is lierda.feishu.cn/.../UH46wkIQSiVPoUkWaaQc9YrcnYb
4. Hypothesis 2: Are the app versions tested consistent?

Best regards

Hi joe_su,

I cannot reproduce your issue following the same steps. The sample works normally for me.

Could you please try to erase the DK first to see if some existing data on flash is the issue?
