Configuring and running the MESH demo

[neostar]

Hi

Usecase:
I would like to control my lights through wifi and since some of my lights are far away from my router, i understand that MESH demo is the right application for this usecase as these devices can make up for that loss in wifi signal. I have the following questions.

[*] From the user guide i understand that the mesh demo does not require a pc to operate or control it, but in the steps to be followed for running the mesh demo i see that demo_server.py is run. Why should i run it ? How to run the demo without running demo_server.py ?
[*] How to configure a device as Root node and as a Non-root node ? Is it auto configured ?

The code i am referring to is --> https://github.com/espressif/ESP8266_MESH_DEMO.git

Thanks

1. You don't need the demo_server.py. when the device fails to connect server, it will switch to LOCAL mesh.
2. All the nodes with the same image bin, and they are auto configured.

@Alan Thanks for the reply.

You are welcome.

@Alan If have 5 nodes flashed with the same bin meaning they all have the same SSID and passcode to connect to the router
I have the following questions :

1. If all of the nodes are in range of the router will all of them connect to the router directly ?
2. If one of the nodes gets far away from the router will that node be automatically connected to the nearest node it can find ?

Thanks for the reply

1. No, when node tries to join mesh, it scans AP around firstly, if it finds mesh AP working, it try to join mesh AP rather than router AP.
If it fails to find mesh AP, it will try to connect router.
2. Yes, when it scans more than one mesh AP, it select parent node according to RSSI/assoc/capacity.

Hi,
@Alen
So what is the role of demo_server.py ?

Will it ever be possible to have both installed? I would prefer to use Mesh for personal things no server required, but Im considering purchasing Pro for our office.

Thanks.
