Question #1: Am i right, that USB and RX/TX are connected, so that only either USB or RX/TX can be used? Question #2: Are there alternative libraries for software serial. In my case for example it causes problems with my Wifi connection. Generally this works, but the Arduino library, which is also available for the NodeMCU (ESP8266), causes trouble with other things going on.
