export ESPPORT=/dev/tty.SLAB_USBtoUART doesn't work, SOLUTION below about esp-homekit-sdk HOT 1 OPEN

@pedros89 , in the same line$ export ESPPORT=/dev/tty.SLAB_USBtoUART #Set your board's serial port here, the comment #Set your board's serial port here was meant to indicate that users should replace this with their device's serial port which could be something like /dev/tty.SLAB_USBtoUART or /dev/ttyUSB0 or COM1 or anything else as per what it indeed is for the device. There was an assumption that the users must have already followed the ESP IDF getting Stared instructions referenced in the README, which has a point about connecting to your device and establishing Serial Connection and so, would know what this comment means. But it seems that people may still miss it. I will add these pointers explicitly in the docs soon enough.
