We need to put a demo program together that interfaces to the ESP32 module. Hopefully we get one in place in the next one to two weeks. The demo will use RS-232 to communicate with the ESP32 module and will show how you can find and connect to an access point.
A release of Linux will be posted on-line in the next couple of days. With Linux, you can use an Apple USB to Ethernet adapter with a powered USB hub.
