[Bluez-users] Apple keyboard problem

[Ian Gulliver]

[-- Attachment #1.1: Type: text/plain, Size: 1036 bytes --]

I have an Apple bluetooth keyboard and mouse.  I can connect to and use
the mouse as expected.  However, attempting to connect to the keyboard:

sheba% sudo hcitool scan
Scanning ...
	00:0A:95:3A:4E:1C	ian’s keyboard

gives me:

sheba% sudo hidd --search
Bluetooth: HIDP (Human Interface Emulation) ver 1.0
Searching ...
        Connecting to device 00:0A:95:3A:4E:1C
Can't create HID control channel: Function not implemented

I never get a PIN entry request (as I did with the mouse) or any other
error.  There's a long pause between the "Connecting to device" and the
"Can't create".  According to lib.c in the kernel, ENOSYS is returned
on an unrecognized error code, but I don't know enough about the packet
formats to figure out what byte is the error code, or what else it might
mean.  Attached is an hcidump during the "hidd --search" run.

Any suggestions would be *greatly* appreciated.

at that pause you should type a numeric PIN on your keyboard and then
press return.

Sorry, wasn't clear enough.  When I'm running in X, the PIN dialog pops
up as expected for the mouse, and not for the keyboard.  The blocking
call for that pause from hidd, according to strace, is:

bind(4, {sa_family=AF_BLUETOOTH, sa_data="\0\0\212\323\4\241\16\0\0\0\0\0\0\0"}, 10) = 0
setsockopt(4, SOL_TCP, TCP_NODELAY, "0\0000\0\377\377", 6) = 0
connect(4, {sa_family=AF_BLUETOOTH, sa_data="\21\0\34N:\225\n\0\0\0\0\0\0\0"}, 10

(pause is here)

= -1 ENOSYS (Function not implemented)

Typing a PIN in that space simply causes the expected:

sheba% 0000
zsh: command not found: 0000

:)

you should type the PIN on the keypad of the Bluetooth keyboard. After
that the PIN dialog should popup and you have to repeat the PIN.
