    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.

    You need to upload the correct drivers and in the ide do you install a new set of tiles? Sometimes I couldn't get the program into the node, but pulling it out for a while and inserting the USB cable again helped and the program loaded normally.

    I have added in the tile idea, and the drivers are supposedly good, but I have windows 8.1 so maybe its the fault. On win xp I tried it and the message popped up:

    Sometimes I had such a message with a compilation error for nodemcu and missing installed libraries .
