Regarding your first question, yes, you can use the functions provided in config_server.c. Just take a look at how the provisioner example does this in the light switch folder.

I do not think 2.6 V is good enough for the custom board to function. Yes, you will need to power the custom board separately (see link).

Thank you. May I just use the functions in config_server.c to initialise a server model and add key and subscription address? If yes, I am unable to find the config_server_appkey_add to add the app key for server. Instead I found handle_appkey_add function which are under opcode handler functions. Should I use the handle_appkey_add function else should I write my own server model defining its functions? In between I found this post regarding self provisioning and the suggested answer to be used without any model configuration. Could please guide me with the steps to proceed with?

I have nRF52 DK, I have connected the custom board as described in this link. The log output is as attached below.

My problem is, the program gets flashed on the external custom board without any issues, after using command window and getting timeoutevent, I check in nrfgo studio for the board connectivity. It shows recover, I couldnt figure why the board gets disconnected, once programmed. I guess dats the reason i get timeout waiting for event.

Even after connecting the board as per the above provided link, should I provide 3V to the board externally? to function else the connection itself is enough to drive the external board. With the help of multimeter I measured 2.6V at the terminal of extermal custom board. Is 2.6V sufficient for the custom board to function?

Thanks in advance

If you want to communicate between the client & the server via Bluetooth Mesh, you will need to bind the app key & setup the publication & subscription addresses.

This will be a lot easier if you have a 52 DK to test with. What timeout event do you receive? Could you upload a log please? This documentation may be helpful.

I want to use nRF Mesh phone app to be the provisioner, Its a requirement, to use serial mesh without PyACI.

To my understanding, I have used Phone app as provisioner, provisioned the server and client, then started serial mesh, sent a message Hello World, which should be received at the server end. Here, I have not assigned a app binding key and publication address to either server nor client. I cannot see the sent message on debug window in Segger Studio. I am not sure if am doing it right. Is appykey binding and adress publication necessary to communicate between server and client else only provisioning them is sufficient?

I am also fllashing the serial mesh example program to an external custom board.The serial mesh example available provides timeout event, when flashed on external custom board and used with PyACI.

Any lead would be great help

Yes, but do you need the computer to be the provisioner or do you want a DK to be the provisioner? You can also provision via the nRF Mesh phone app. Why do you not want to use Interactive PyACI?

I want send and receive data without PyACI. Is it possible without using a model via serial mesh?

I do not fully understand unfortunately. Do you still want to provision via a computer, just without using interactive PyACI? Or do you want the dev kit to be the provisioner?
