First study Mesh

[tony55723]

Hello,

I found this picture on Nordic's official website

1、Can only proxy node connect to mobile phone and GATT?

2、

I open mesh example (dimming), which contains client and server

My understanding is

Client can achieve P, RN and FN

Server can achieve N, LPN and GATT

Is my understanding correct?

3、Assuming that I understand it correctly, which code can make these settings in example?

Thanks

Should this be a successful implementation?

But I still display the error below in NRF connect（v3.6.1）

Thank you

Hi Tony, 
I would suggest to try installing Jlink driver again. Aslo please upgrade (or reinstall ) nRF Connect app. The latest version of nRF Connect is v3.7.0 and the programmer is v1.4.11

Or you can just use the nrfjprog.exe to program , it's my preferred programmer if you are familiar with commandline tool. 
Note that you can use Segger Embeded Studio to program the chip after you compile the application.

I currently use command line to erase the chip, and then use SES to download the program

I have now downloaded the sample program light_ switch

The function should be successful

But I have a few questions

1、In nRF Mesh APP for iOS, why does the client have 3 elements?

(How should I understand element?)

(Server has only one element, And I only set client Element2)

=================================================

2、In my video, example is light_ switch,

The board of the client should be a proxy node,

What kind of node does the server board belong to?

Thank you

Hi Tony,

1. Two same model can't be on one the same element. This is the reason we have multiple elements because we have multiple OnOff clients. Please study the Mesh specification here or the quick start guide here. 

2. The server node a normal mesh node and it's also a Proxy node at the same time. It can also act as a friend node.

Can a node have multiple functions?

I always thought was that a node can only have one mode

This Server contains proxy node and friedn node?

Thank you
