ESP32 Forum

I just received my ESP32-DevKitC and I'm trying to figure out how to communicate with it via my MBP running MacOS Sierra.

I tried comparing the output of ls-al /dev/tty* before and after plugging in the USB cable. Unfortunately, no additional tty port is showing up. I know El Capitan made some changes which blocked the uncertified drivers some of the FTDI chips for the esp8266 dev boards - so I suppose its possible that the DevKitC isn't compatible, though I hope not...

Does anyone know which port I should be looking for?

Have you installed Silabs VCP driver? DevKitC should show up as /dev/tty.SLAB_USBtoUART.

@ESP_igrr
Thanks so much - that was the problem!

For those who follow here's the download location: http://www.silabs.com/products/developm ... cp-drivers

I did search to try to find the solution before posting here.
E.g. Various web sites, read the following (but, unfortunately, none mentioned needing the driver):

• http://esp-idf.readthedocs.io/en/latest ... setup.html

Thanks again!
