My kit is not working. Compiling goes ok. Wifi scanner goes ok. Then i get a blank screen. When i touch the screen the blue led begins to flicker, Normally the blue led doesnt flicker. I'm an arduino noob, i have no idea. I expected a out of the box working kit. I ordered 5 kits. Another question is i must use the board NodeMCU 1.0 but my kit contains a Wemos D1.
