USB-stick methode at changing WiFi SSID

I want to change the SSID of my HA-installation and I am going to use the USB-stick method as described in step 4 of this post:

My question regards the content of the “my-network” file.
I use the “Wireless WPA/PSK” section as template…

… and will configure my SSID en pwd (yellow high lighted).

But what to do with “uuid” (green high lighted)?

Can this be ignored, should it be removed, or ….?

I have running and operational HA and don’t want to break it.

Regards, Ko

Generate your own V4 uuid:

This was in the linked examples:

I generated this uuid and now my RPI connects through wi fi.
