Re: [Bluez-users] Can't connect RFCOMM socket

[Filipa Duarte <filipa_duarte@yahoo.com>]

Hi everyone,

Marcel, many thanks for your help, but I still
couldn't connect to my friend PC. So I decided to
connect to a mobile phone first. It is an Sony
Ericsson Z600.

The 'hcitool scan' shows me the phone and the phone
also recognize my laptop. After this, I did a 'rfcomm
bind' on the laptop.

When I try to connect the mobile phone to my laptop,
the mobile phone asks me the passkey. When I
introduced the PIN (the same I have defined in the
/etc/bluetooth/pin) the reply on the phone is 'passkey
mismatch'.

Here is the output of the 'hcidump -X':

Could you please help me with this output? I am not
sure what it means, if the PIN helper is working or
not...

If it is not the PIN helper, could you give any
directions to look for the problem?

Many thanks. Regards,

Filipa
