WPA3 SAE transition mode connexion issue AP mode

Hello,

I am using Leap 16.0 on my servers, and I am creating an access point (AP) network using NetworkManager 1.52.0.

Here is my NetworkManager configuration:

In the NetworkManager journal logs, I see the following entry:

NetworkManager[3563685]: <info>  [1775051048.7146] Config: added 'key_mgmt' value 'WPA-PSK WPA-PSK-SHA256 SAE'

Most of my Wi-Fi clients can connect without any issues. However, I am experiencing problems with Zebra and Elo tablets, which are unable to connect. On their Wi-Fi interface, the network is detected as WPA3 (SAE Transition Mode) .

I contacted Elo support (part of the Zebra group), and they indicated that the issue is likely related to the Wi-Fi server configuration.

Could you help me understand what might be causing this behavior?

Is it possible to disable WPA3 transition mode and force WPA2-only when using NetworkManager? Alternatively, would switching to hostapd (or another solution) be required?

Thank you in advance for your help.
