- run this command for check actual tty state.
ls /dev/tty.*
- On some pc with usb-c you could se device like:
ls /dev/cu.*
- Now connect device to USB, rerun the command and check changes in output. We should see like
/dev/tty.SLAB_USBtoUARTor something similar. If not go to this page and download CP210x USB driver.
IMPORTANT! Use only data usb cabel. I and a lot of people on this world spend many many...
time connecting device with wrong cable only for powering.

Download MicroPython for our Nodemcu(esp8266) module. You can download it from this page. My latest choice was
esp8266-20191220-v1.12.bin. -
For deploying we will use esptool which can install it using pip:
pip install esptool
- Erase flash.
esptool.py --port /dev/tty.SLAB_USBtoUART erase_flash
- Deploy flash.
esptool.py --port /dev/tty.SLAB_USBtoUART --baud 115200 write_flash --flash_size=detect 0 esp8266-20191220-v1.12.bin
