This patch series adds support for hexadecimal encoded pins. This is no final patch and I would be glad to get some feedback. This patch series solves the problem that the current bluez implementation does not allow binary PINs that contain ASCII \0 characters. This is needed for several devices that take bluetooth addresses as PINs. I had the following ideas to implement binary pins: - Hard coding binary pins into bluetoothd by detecting the device with PnP VID/PID information as suggested by Marcel Holtmann. However, this is not possible (as noted by Bastien Nocera) because devices may refuse to offer SDP information for unpaired hosts. Furthermore, SDP records are retrieved after pairing with the remote device unless they're cached. - Adding a new dbus agent interface that returns pins as byte-arrays instead of 0-terminated strings. However, this either breaks backward- compatibility or needs _huge_ additions to the dbus interface. - Adding escape-sequences to pins or special pin parsing. This does break backward-compatibility but may be implemented in a way that reduces problems to a minimum. I implemented the first approach a week ago as discussed on the mailing list which turned out to be not appropriate. The second approach is probably the cleanest one but requires huge dbus API additions. This patch series implements the third approach. See patch 3/4 for details on the suggested PIN encoding. Pin encoding with the dollar sign is just a temporary approach which makes the implementation quite easy and shows the idea of this patch. However, the encoding is of course open for discussion. Binary pin support is inspired by getting Nintendo Wiimote pairing support. To test wiimote pairing with this patch series, do the following: - assume the local bdaddr is: 01:23:45:67:89:ab and the wiimote bdaddr is: ba:98:76:54:32:10 - Pairing with red-sync button, use pin: $ab8967452301 (host addr. backwards) - Pairing with 1+2 buttons, use pin: $1032547698ba (wiimote addr backwards) Automatic reconnection is only enabled in the wiimote when synced with the red-sync button. The 1+2 button method is only for temporary connections.
