Flashing ESP-32 with Firmata doesn't involve server/client mode and port configuration

[yentsun]

While its impressive that IoTit can flash Firmata on ESP-32 (and Arduino IDE version can not) I couldn't choose between server/client mode to actually get a flashed ESP-32 working.

With Firmata for Arduino IDE I can set up the ESP to be a server (which requires to set the port) or a client (requires to set server IP and port) but with IoTit I'm only asked about WiFi SSID and password.

I would assume that my ESP is now running in server mode (as its more common), but what is the port then? 3030?
