SuperB + M2: WIFIScan not working

I worked through the “Getting Started” section in the “SuperB Docs”. All went fine up to step 2.7 (In step 2 I selected the “M2 + Arduino IDE” tab): Uploading the “WIFIScan” example . This example doesn’t compile for the previously selected “SuperB on M2” board. All constants (i.e DS2, DS3, XBEE_RST) are not defined! The sketch compiles fine when the “Macchina M2” board is selected.
What is wrong? What can I do?

Thanks in advance!

Ok, so it seems to be a version issue. With version 1.0.4 of esp32 it didn’t work, but with 1.0.5-rc6 it does.
