Hello, I have purchased a Nodemcu v3 chip with CH340. When trying to upload the program via arduino ide 3 messages pop up:
warning: espcomm_sync failed
error: espcomm_open failed
error: espcomm_upload_mem failed
When I open ESPlorer nothing happens either, it doesn't connect to the chip, in windows device manager it is seen "usb to serial". And hence my question - has anyone had this problem before and knows how to solve it.
