build BLE-Mesh with multi provisioners (Clients) and one OnOff node (Server)

[mm_1993]

Hi
how to build multi provisioners with mesh network ?
I want to create a bluetooth mesh application with at least 3 clients that connect to one OnOff server node and each client able to control node onoff server LEDs
I know I can use example onOff-server (as my server node) and onoff-client (as my clients)
but it does not work
after one client connecting it is not possible other one connect to the node

anyone have a sample code?

I Really need this
