Just installed ardublock-all-master-beta-20171028.jar from Releases · taweili/ardublock · GitHub
and
tested it with Arduino IDE 1.8.5 on an RPI3.
Previously I had to use IDE 1.6.12 with the ardublock-161216-carobot.jar. When I used this with 1.8.5 there was a error associated with SCoop.h
Now my program compiles and runs OK.
Ardublock is a very nice tool for occasional Arduino programmers.
