It is possible. However there's a problem when AP and station (client device) are running different generation of wireless drivers (OmniTik 5ac might be running older wireless drivers while SXT 5ax will almost certainly run newer wifi drivers) where it is not possible to configure station in any of "bridge" modes (e.g. configuration.mode=station-bridge) due to incompatibility between the two wireless driver generations. Setting mode to station-pseudobridge should be possible but that mode comes with drawbacks.
Good morning, I have tried that configuration mode and it still won't connect. That is, the devices can see each other but there is no transparency, no ping.
"I'm sharing a screenshot of the OmniTik, the MAC ending in 50:11 is the SXT 5ac."
