Hi,

I am happy to hear that you solved the initial issue. Thank you for sharing the link to the thread that helped you solved it.

Regarding your new list of problems, I can give some short answers to some of them here. For the rest, please create separate threads with descriptive names. They span several areas of SoC development, and should be handled individually. This also makes it easier for others to find answers to their similar questions in the future.

1) From the nRF Mesh app you connect to the a node on the Mesh network. If a model on the Dongle is subscribed to a group address, you can go to the Groups tab in the app, select the group, and use the interface.

2) One example of sending data to and from a PC is using serial such as in the Mesh chat sample.

3) Please create separate ticket for this hardware related question. Please note that this is a very generic question, and we cannot provide a detailed list of steps for implementing this. We, or others in the community, may have some general tips and ideas, but you are expected to do the work yourself.

4) While our DKs can be used as programmers, and the Dongle can be programmed that way if you have the correct cables and do the programming correctly, we really recommend using DKs as a basis for development. Especially if you are going to connect other components such as segmented displays. Please note that the DFU solution delivered with the Dongle is from the nRF5 SDK, so in order to use the Dongle with nRF Connect SDK you must program it using a programmer. Note also that most mesh examples are supported on the DKs, but not listed as supported by the Dongle.

5) Those are two separate issues, not closely related to the original question. Please create a separate ticket for the build issue. Regarding "unprovisioned nodes", do you mean "unprovisioned beacon"? If you are unable to build, then there is nothing to program onto the board. What did you put onto the board if the project did not build? It is best to start with a ticket with the question regarding your build issue, with a complete description of what you do (which example, which SDK and version, and full build log with all errors.) Then, when you have solved that issue, and been able to program the board, you can ask next questions regarding not seeing the board broadcasting, and so on. One thing at a time.

Regards,
Terje

Provision solved Ticket

I have solved that unprovisioning problem from the above ticket.

I have also flashed
1) Mesh Light Switch example
2) Mesh Light Dimming example
to the nRF52840 Dongle. It worked perfectly fine and I can provision the nodes and control the inbuilt LED through the Mesh app.

Now, I have some problems.
1) How to send messages to Dongle from Mesh app?
2) How to read that data received on Dongle in PC?
3) I want to connect a 7 Segment display to the dongle, which can show the received messages(numbers only enough) from DK or nRF Mesh app. What are the steps to
get that?
4) Can we flash Mesh programs to the Dongle from DK using VS Code? is there any other way to do that?
5) After flashing Mesh Serial example, I don't get any unprovisioned nodes from it. When building it also causes error as "UART pins are not defined". How can I solve this?

Please answer as soon as possible.
Thankyou.
