Hi,
I cannot pair my ipaq 2210 (with Zeevo TC2100P chip attached via hciattach and familiar 0.8.4 distro, kernel 2.6.15-hh2)
and my cellular phone nokia 6230i. Doing some research
I found out that my phone does not like unit keys and the ipaq
uses them. On pocketpc these problems also exist. But there is
a bluetooth security update which somehow enables the use of
combination keys until the next hard reset.
But... how to fix that on linux?
Here are some logs:
When paring the two devices:

some citations about the problem on pocketpc:
Some citations:
from: http://www.ppc-welt.info/community/archive/index.php/t-45005.html
"This is a Hardware issue and not a software issue related to the
WIDCOMM BTW-CE Product. The reason for this problem is as follows:
There are two types of keys that can be used for pairing:
- Combination keys
- Unit keys
The key type that is used is pre-set in the Bluetooth Radio Firmware. The WIDCOMM BTW-CE Bluetooth software does not control this setting. The radio on the iPaq 1940 uses unit keys by default. The Nokia 6820 phone rejects the use of unit keys in pairing because it is not as secure as combination keys.
This issue has been reported with Nokia 6820 and 6230 phones when
attempting to pair with the iPaq 1940 or 2210 PDA."

"Adds support for Combination Key. Some Bluetooth devices require
Combination Key support in orde to pair with the handheld device."
So what can be done to achive the same on linux?
Thank you in advance for your answers.
