[Bluez-users] Pairing a keyboard

[Bluez-users] Pairing a keyboard

[Chris Frost]

When trying to pair with an apple wireless keyboard, hcitool cc errors
"Can't create connection: Input/output error". I was hoping someone
might have a suggestion on what to look into.

The details:
I'm kernel 2.6.9-mh4 and bluez 2.11 on an x86 with a D-Link DBT-120.
After starting hcid I run "hcitool cc <addr>" and get the error above.
I've included "hcidump -x"'s transcript at the bottom of this email.
bluepin does not work on my installation (pygtk seems broken), so I wrote
a script to echo "0000" to stdout. This may well be my problem? I do not know
if this is the format hcid is expecting or if it is the initial pin apple
sets. I did read that the mouse uses this pin, this is the only reason for
my choice. For my hcid.conf file, security is auto, pin_helper is set to this
script, and auth and encrypt are commented out.

I am able "hcitool scan" to see the keyboard. I'm also able to pair with
an ericsson phone. The phone, however, may not use a pin?


hcidump output:

< HCI Command: Create Connection (0x01|0x0005) plen 13
  4B 9A 3B 95 0A 00 18 CC 02 00 00 00 01

thanks for any suggestions or pointers!

who said that pairing works by calling "hcitool cc ..."? You should use
the "hidd --connect ..." command instead.

The bluepin script must echo "PIN:0000".

No one did; I had tried hidd --connect but got the same errors. Sorry about
this mistake, thanks for the correction.

Aha, that gets it. Thank you.

Do you know if I should I read about/look into putting the keyboard to
sleep after inactivity? I have read in a couple places on the web that apple's
devices do not go to sleep themselves, but perhaps what I read was old and
bluez does this automatically now?

the hidd has a --timeout option you can use, but we don't support the
automatic switch into sniff mode.
