Hello,
we are working for some months on a b4x project that needs to connect to Arduino controller. it is working great on our developing Arduino. now we start to move to production version and they changed the Arduino chip, and the app doesn't recognize it. (it is working with UART adapter).
The controller (chip) developer says that we should install a usb2 driver on the android.
I wanted to ask if it is correct, should I install a usd2 driver? and if so, where and how can I find one that will suit b4x.
thanks a lot
