I am trying to create a bluetooth adapter which allows me to connect my keyboard + mouse via bluetooth and act as an HID device on my computer via USB. I want to be able to switch between operating systems, and use grub without having to use a wired keyboard (similar to the logitech unifying adapter)
Keyboard/mouse --BT--> Audrino --USB/HID--> Computer
I dont know the name of this type of device to search, but I have looked into bt hid proxy and have run into a dead end.
I have heard you can make this with a Arduino pro (I currently have an uno)
