Xiaomi MI A1 as a wifi repeater

[tattare1987]

Goodmorning
I have both a Xiaomi MI A2 lite (cr droid installed) and a Xiaomi MI A1 (evolution X installaed).
I would like to use them as wifi repeater.

I tried to switch on both the wifi and the hotspot toggle but only one of them can work, they can't work togheter.

Then I tried to select Enable Wi-Fi Coverage Extend Feature in the "developer option" and do again the point above.

Nothing of that work.

I don't want to use apps like "Wi-Fi Repeater" because I need to install an app also in the devices connected to the repeater.

Any ideas?

Thanks.
