would it be posible to flash an ESP-12F with a D1 Mini? I know that it is posible with the NodeMCU board: https://circuitjournal.com/esp8266-with ... th-nodemcu
But the D1 Nano doesn't have the pin EN to disable the chip.
I have read some comments that it could be posible but both boards would get flashed at the same time, what wouldn't be a problem.
Is it really posible and safe?
