I'm wanting to do a project with a Raspberry Pi acting as a Bluetooth keyboard and/or mouse. The Pi would be connected to a touchscreen display, and I would have a virtual keyboard on the screen that I could tap on.
I have a Raspberry Pi 3 B and a Raspberry Pi Zero W, and am open to using either one for this.
Is it even possible? I don't see any reason why, by creating the right signals, you couldn't make the Raspberry Pi send bluetooth signals...but I'm not very educated on this.
I've seen this post for the keyboard problem, but working with a mouse might be harder?
