I once wrote an app for Windows Mobile that implemented the L2CAP bluetooth protocol, and implemented the HID spec. This allowed phones to appear as bluetooth mouse/keyboards and be paired. It used the accelerometer and touchscreen to allow for cursor manipulation and had an onscreen keyboard for typing. Took me months to figure out the Bluetooth driver and to debug the HID issues, but when it worked, was pretty exciting. Just dug up an old analysis of it too https://forum.xda-developers.com/showthread.php?t=504730 |
