How to connect to your ESP32 on macos

To find out as what USB device the ESP32 is connected, open Terminal and enter:

ls /dev/tty* | grep usb

in my case I got

/dev/tty.usbserial-14120

Now we can connect via screen:

screen /dev/tty.usbserial-14120 115200

When you reset the board you should see something like this

configsip: 0, SPIWP:0xee
clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00
mode:DIO, clock div:2
load:0x3fff0030,len:5656
load:0x40078000,len:12696
load:0x40080400,len:4292
entry 0x400806b0

To end the session in screen, press Ctrl+a, and type :quit and press Enter.

File "", line 1, in 
AttributeError: 'module' object has no attribute 'name'
>>> import platform
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: no module named 'platform'

UOS for the rescue
