We only have what is already present in the samples. I think the "easiest" way would be to look into the chat sample, look at what OP codes that you need to use, and then test it from the phone app like I described in the previous reply. However, it is not very convenient to have to write these hexadecimal OP codes every time, so you probably need to develop a custom application at some point.

Dear Edvin:

Thanks a lot. There a link of vendor model development as the following.

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/protocols/bt_mesh/vendor_model/dev_overview.html

https://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.meshsdk.v1.0.1%2Fmd_doc_getting_started_how_to_models.html

We would like to add the vendor models to light_switch server example. Is there any sample code of the vendor model for reference?

Hello,

Open the Network tab at the bottom, then select the node containing the model that you want to use, expand the "elements" element, and click the model that you want to use. If you scroll a bit down, there should be a field that says "Controls", where you can enter an Opcode and parameters. I believe this is what you need to use. This is not a very elegant way of sending strings, and they have to be in hexadecimal values, but it is possible for testing. If you intend to have an app that you can send custom strings to the network, I think you need to implement this in a custom mobile application.

Best regards,

Edvin

Dear Edvin:

Thanks your help.

I only have a android cell phone and can't find the path: "Node -> Element -> Model -> Custom UI " in addroid mesh app.

Could you help test android version?

Hello,

I have only tested the iOS versions, but can you please try the following:

Go to Node -> Element -> Model -> Custom UI to send messages on that node. E.g. for Vendor messages. Note that for Vendor Messages, you need to specify the Raw value.

Best regards,

Edvin
