Wiimote Hacking: Is a PIN even needed?
While scanning the web for new Wiimote hacking information, I found this post about a guy who claims to have paired his Wiimote with his Windows desktop:
Gamer discovery: Wiimote to PC pairing
From the looks of it, no PIN was used at all. This is not at all what I observed when testing with the OS X Bluetooth Setup Assistant. Although, I can’t tell if Windows uses an empty PIN or skips the PIN entirely (still don’t know what that means precisely). If I try the “skip the PIN” method, I get a success message from the Setup Assistant, but nothing is shown in the list of connected Bluetooth devices. Perhaps I should investigate that more, however.
Based upon the Windows reports, the Wiimote does not appear to send packets like a standard keyboard or mouse device, which is not surprising. However, with any working connection, it should be possible to start dumping packets and reverse engineering the data format.
