I have a project that sends commands to a robot. I have used Xojo for years and it has always worked.
I just downloaded 2019 R3 and updated it on my Mac.
I got it working just fine.
I then moved it over to my windows machine and it is not working!
To communicate with the robot, I send out a couple of bytes to initiate it. The last byte is a "05".
This is echoed back. I read it fine.
I then send out "85". This is echoed back by the robot. I receive it on mac but not on the windows 10 machine. It used to work with the older Xojo.
I have tried putting in delays with app.sleapcurrentthread, xmitwait, SerialPoll, etc.
The only thing that I have been able to get to work is to send the "85" a second time!
I am still using the older Serial as I could not for the life of me get the new SerialConnection to work.
Any ideas why I can't read this byte?
