BLE mesh not sending messages when debugging from a different computer

Hi SS,

Thanks for letting me know about the finding. It's quite strange that only when debugging the issue happens.
I would suggest to try with the recommended SES version of 6.16a as in the documentation for nRF5 SDK for mesh.

The machine that the debugger is attached to is running Windows 11 and the computer that I use to access the Windows machine is running Ubuntu 20.04. I do use a remote desktop kind of way to access the Windows computer.

[quote userid="2121" url="~/f/nordic-q-a/89483/ble-mesh-not-sending-messages-when-debugging-from-a-different-computer/375004"]Do you have any trouble if you debug directly from the first Windows machine that connects directly to the DK via USB ? [/quote]

When I debug from the Windows machine then I can run the debugger and provision my device. The problem is after it finishes provisioning then it will timeout during the "Status Requesting Composition Data..." process and I get an "Error Request timed out." on the phone that I use to provision the node.

After this happens I cannot add an "Application Key". I cannot even "Reset" the node.

When I am debugging from my Ubuntu machine, I have no issues whatsoever. I can debug, provision and control my servers after provisioning the node.

The odd part is that I have copied and pasted the entire SDK and examples from the Ubuntu computer to the Windows machine. I have actually successfully done this on other computers and it works fine, just not on this Windows machine.

[quote userid="2121" url="~/f/nordic-q-a/89483/ble-mesh-not-sending-messages-when-debugging-from-a-different-computer/375004"]When you do provisioning, can you do "Identify" the device ? How did you do provisioning, via a phone or via another DK ? Have you tried both way ? [/quote]

I use an iPhone 13 to provision the nodes using the mesh APP. I have also used an Android tablet to provision the nodes as well and it doesn't work when I program the node with the Windows machine.

I have noticed that when I look at the device memory layout in nRF Connect Programmer after programming with the Windows machine and compare it to the device memory layout after programming from the Ubuntu machine the Application region is different. The softdevice regions are they same.

After some time of looking into this I eventually got it to work with a very simple solution. I downgraded Segger Studio from V6.32b to V5.40c and everything just worked.

Thank you

Hi SS,

Have you checked if there is any log on the DK when you provision ?

It is just a windows machine that I can connect to remotely through a VNC. I have the DK connected to the Windows machine with a USB cable.

[quote userid="2121" url="~/f/nordic-q-a/89483/ble-mesh-not-sending-messages-when-debugging-from-a-different-computer/374888"]Have you tried to debug any simple application and check if it can step in the code and can operate normally ? [/quote]

Yes, I tried the 'dimming' example and it seems to work from a fresh downloaded mesh SDK. When I use my code that works on the other computers, I can provision the node but it times out while 'Requesting Composition Data'. It is almost as if the mesh features are not there.

Thank you
