[Bluez-users] bluetooth ipaq problem

[Sébastien Delneste]

Hello,

I'm having a serious problem with an iPaq 3870 running Linux (Familiar)

6 months ago, I've been trying to change the PS registers of my CSR
chipset (using the pskey tool)

Since then, my bluetooth hasn't worked anymore.

Today, I finally found back the URL I was looking for with the default
values of the registers.
http://www.samengstrom.com/ipaq/PSKEY-README

I've restored one but, apparently I failed to modify the second one,
which results to the following problem : 

I still can't use the bluetooth function of my iPaq and I can't access
it with pskey anymore 

the values are now : 
1f9	0001
191 01d8 00a8 00fa 0014 0004 0000 0004 001e 0064 000a

now, when I try to use pskey (no matter the speed , I've tried
15200,230400, etc), it gives me the following error :

~ # pskey -d /dev/ttySB0
Physical device :/dev/ttySB0
Speed           :115200
Use BCSP        :NO
Initiating read thread
Now trying to read firmware info
Timeout!!!
Error in reading firmware info


Is there anyone out there who already had this problem ?

I've also heard of pstools (apparently pskey but under PocketPC), could
it help in my case, where can I find it ?

Thx for your help,
Seb

playing with the CSR PS and not really knowing what you are doing is
dangerous, because you can set your Bluetooth chip to a non working
state. The archive contains some post from CSR guys that may can help
you, but actually I think you broke it. Btw you never had to do this
modifications, because the iPAQ is working out of the box ;)

Regards

Marcel

Well, now, it is working out-of-the-box, but it hasn't always been
true... it used to be required, otherwise I wouldn't even know that CSR PS exist

Thx,
Seb

you wrote six month ago and actually at that time we already support the
BCSP protocol ;)
