Is it possible to upload a program from the R+ Task Android application to the CM-150 controller via a USB cable connection?
Where does the Task Android app run from? A Tablet or phone? With a USB port? What kind A connector? C connector ? Micro USB?
Back in 2022, I was using a Chromebook to work with CM-150, that Chromebook (Chrome OS) did not support USB ports. But I think that the newer Chromebooks support USB 4 now, but I do not have one to try out. 
i am using samsun galaxy tab a9+ (sm-x210)
I only have a Tab S6 Lite and I just verify that TASK 3 Android App could not find the CM-150 if it is connected to the USB C port of my S6 via an USB OTG cable. So I expect that the Tab A9 will also not work via the USB port. So stay with BT-210/410.
