I am trying out the project here:
https://www.b4x.com/android/forum/threads/lcd-clock-example.65726/
UNO R3 is connected to COM39 and compiled/installed the B4R project to the Uno R3 successfully. The LCD display shows "waiting for time".
The B4J project list COM39 but when I try to connect I get this error:
The post seems to be busy - I can however compile and run the B4A project without any hassle. I don't have the Arduino IDE open so the port is not locked by the Arduino IDE.
Any suggestions how to solve this will be much appreciated.
