Possible MQTT (mqtt_as) usage without Wifi

[nastiliano]

Hello,

It's possible to ignore config["ssid"] and config["wifi_pw"] due to previously self-configured WLAN settings?

Thank you very much.

Happy new year.

I wanted to use mqtt_as with PPP-over-serial.
ie, I don't want to use WiFi.
Is that possible?
