Hello,
I'm using a Zaurus 3100 with a Socket Bluetooth Card. I'm connecting to my Ericsson w810i using qtopia bluetooth applet to dial-up to the internet. Everything works fine. My issue is this:
Everytime the Z dials the phone, the phone asks for the Z's PIN. I always enter the pin and always get a connection. How come the phone always asks for the PIN? I thought after initial pairing, it shouldn't happen again. I don't want to have to take my phone out of my pocket to enter the PIN.
I have told the phone to "Always Allow" the Z, but it always asks for the PIN.
Does anybody else have this issue with their phones?
BTW, my Palm Tungsten E2 can dial-up w/o password after the first pairing occurred, so I assume this problem is in the way the Z negotiates BT connection with phone and not a problem with the phone.
FWIW, here is the INIT string for the Palm
E0X1+CMEE=1;+CMGF=0;V1
Also, FWIW, the phone is listed as a "Trusted Device" on the Palm. Where is the list of "Trusted Devices" on the Z?
TIA

When I was running w/ Cacko it would do the same thing. I haven't noticed it with pdaXrom. Did you try changing the pin in /etc/bluetooth/pin ???

Actually what ROM are you using????

More info.
Removing /etc/bluetooth/pin does nothing. It still works the same.
HOWEVER,
commenting the line
echo "PIN:1234"
in /usr/bin/bluepin causes the phone to reject the Bluetooth connection. It still asks for a PIN, though.
It seems the phone wants to add the Z every time,
and then I enter my PIN into the phone,
which is validated by the Z's response from /usr/bin/bluepin
-
Just doing a
rfcomm connect 1 00:16:XX:XX:XX:XX
causes the phone to prompt for the PIN as well.

it should really be
echo -n "PIN:1234"
or even
echo -n "PIN:"
cat /etc/bluetooth/pin
where /etc/bluetooth/pin contains just "1234" with no end of line.

Thank you, but sadly it did not work.
I tried both of your suggestions and I still get the prompt from the phone.
Where exactly in the stack does the pairing process occur? It's almost as if the Z presents itself to the phone as a different device each time.
I wonder if I try with my Ubuntu desktop if it would behave the same.
-
This is just a shot in the dark, but would the OBEX Push service help?
I noticed that my laptop (running windows and bluesoleil) and the Palm (this is the only service running on the Palm) both have this service running when I browse services from my phone. When I browse services from my phone on the Z, it says nothing is running.

look for a file called /etc/bluetooth/link_key or similar, delete it (it's the Z's database of paired devices), then on the phone delete the pairing, and turn it off, remove its battery for 10s, then power it on and try pairing again.
p.s. ensure that /etc/bluetooth/hcid.conf has a static name defined for the Z, i.e make it hard-wired.

no, I don't think so. this is a much higher level than the pairing process. you can tweak the device ID if you wish. I modified the hcid.conf on my server so I could play...

the device class is supplemented by the SDP daemon announcing what is running.

Thanks! That worked! The only difference is that I had to delete
/var/lib/bluetooth/xx:xx:xx:xx:xx:xx/linkkeys
I dial-up to the zaurus and in seconds I'm online using Cingular. This is awesome. My phone stays in my pocket , which used to be soooooo annoying before when I had to always enter the pin.
Thanks again.

sounds like the linkkeys file had become corrupted, so although the Z did the pairing each time, when it stored the keys it couldn't reuse it and created a new session key each time.
I used to have this sort of problem when I only had one BT dongle (when they used to cost 50 dollars+) and transferred it from PC to PC, it used to confuse my Palm and Zaurus and I had to jump through hoops to unpair and re-pair. Now dongles are just US$15 I have three (well, two, I lost one on vacation, sadly, the best one :-(
glad to help.
