I want to flash micropython on an ESP8266-01, using this wifi adaptor.
Since I don't succeed in doing so (fail using esptool as I do with other ESP8266/ ESP32 I use), I'm asking for your assistance in this procedure, mainly what is the functionality of switch on module.
Installation. Tried to install using installation guide,—didn't pass to level 1.5.
Tries descripbtion:
1) install drivers
2) driver detected on OS:
MacBook-Pro:~ guy$ ls /dev/tty.*
/dev/tty.Bluetooth-Incoming-Port /dev/tty.wchusbserial1430
3)switch toggle on USB adapter to prog.
4) connect to mac ( using usb C adaptor ).
5)1st try, react OK:
MacBook-Pro:~ guy$ esptool.py --port /dev/tty.wchusbserial1430 flash_id
esptool.py v2.5.0
Serial port /dev/tty.wchusbserial1430

6) ANY additional command needs plugging adaptor out, and back in ( empirical - don't know why ),
7) erasing ( took 0.0 s ?? ):
MacBook-Pro:~ guy$ esptool.py --port /dev/tty.wchusbserial1430 --chip esp8266 erase_flash
esptool.py v2.5.0
Serial port /dev/tty.wchusbserial1430
