You should be able to use a USB Host Mass Storage library for your controller.It’s my own design, but I want it as a file, not a bunch of data in a terminal window.
I’m abandoning this idea, as Bluetooth file transfer seems to be somethin that Windows and Linux does, and Apple doesn’t.
My processor* has a USB interface, I’m exploring whether it can write files to a USB memory stick and whether there might be an API which does the job for me.
