I bought an NodeMCU. So today I downloaded the Arduino IDE (Version 1.6.9) for Ubuntu. I installed it with install.sh. Then I opened it up and added the additional board manager for the ESP8266 and installed the esp8266 board from the board manager. Moreover I changed the port to /dev/ttyUSB0. Then I opened the example blinking code and changed the the Port to 13. Now I uploaded the code to my NodeMCU. On the bottom of the screen the number increased to 100% and during this the led of the NodeMCU blinked. When the upload process finishs, the led turns off.
Does anyone know, why it doesn't work. Do I have to install some additional divers on Ubuntu?
