It’s about the Display “Terminal” in the Blynk app.
I’d like to send messages from my Blynk main.cpp (Raspberry Pi, C++) to my smartphone.

I get the following error:
main.cpp: In function ‘void BlynkWidgetWrite0(BlynkReq&, const BlynkParam&)’:
main.cpp:54:12: error: ‘class WidgetTerminal’ has no member named ‘println’
terminal.println(“Hello”) ;
^~~~~~~
make: *** [Makefile:70: main.o] Fehler 1

I tried to use the expample from https://examples.blynk.cc/?board=Raspberry%20Pi&shield=System%20default&example=Widgets%2FTerminal but it doesn’t work.
