I work with esp8266 (Wemos D1 R2)
after erasing esp memory and flashing with micro Py
xxxxx.bin as you demonstrate in “your ebook”
i load the flashing led example
It is ok.
after i disconnect usb (Dell Precision W7 pro esp8266)
it is ok after i use the Thonny IDE
the power is provided by external supply
then i reset (button) or / and power off supply
after power on again the esp board , the led in NOT blinking anymore
like the uploaded micro Py example has gone…
what happend ?
boot.py issue or ?
