Is there any progress on the project?
[div align=\"right\"][{POST_SNAPBACK}][/a][/div]

Yes, there is some
Actualy we have two C7x0 with an integrated bt.
Bt is connected to FFUART and power control schematic is here:

Anton,

Are you talking about your c860 or c1k? If you guys find a way to trace btuart lines on c1k's pcb, please let me know. I'm not ready to lose my ffuart yet, still need it for serial communications. Also, if anyone would be brave enough to desolder pxa270 from C1k/c3K/c3.1K pcb, I'd like to see hi-res pictures.

It's still my C760 with a black keyboard from a C700 and black screen from C750 with 128 Mb or RAM and soon-to-have bluilt-in bluetooth

And we have plans to solder 128 Mb of RAM to my C1000 too...
[div align=\"right\"][a href=\"index.php?act=findpost&pid=96129\"][{POST_SNAPBACK}][/a][/div]

I have success with an adaptation of the Albert's serial driver to run on PXA25X. Bluetooth is seems to be rock stable now.

I've just received my renewed C700 from Maslovsky  Not it has a new PXA255 CPU and 128 MB RAM onboard. I will try to solder BT module to FFUART again.
[div align=\"right\"][{POST_SNAPBACK}][/a][/div]

Is that 128 RAM, or storage space?  Is there a thread somewhere describing/discussing the process?

Cheers!

128 MB of RAM.

Interesting... I'm using Affix and bcsp support seems to be ok there.

[div align=\"right\"][a href=\"index.php?act=findpost&pid=96059\"][{POST_SNAPBACK}][/a][/div]

The problem isn't in bluez, i think. It's seems that the sharp's serial driver couses some memory corruption.

I was just wondering if you overcame that kernel panic problem you had.  Well, congrats on your 128MB C700 revival!
-albertr
[div align=\"right\"][a href=\"index.php?act=findpost&pid=96055\"][{POST_SNAPBACK}][/a][/div]

I just made a small workaround. But the problem is still exists. When HCI layer is calling serial driver write function this sometime couses bcsp layer's pointers corruption.

2x4ever,

Just curious how did you make it out?
-albertr
[div align=\"right\"][a href=\"index.php?act=findpost&pid=96044\"][{POST_SNAPBACK}][/a][/div]

What do you mean? How did i soldered it and where? I've soldered it to STUART. But STUART is sucks. Doesn't actualy working at speed > 38400.

I've just received my renewed C700 from Maslovsky  Not it has a new PXA255 CPU and 128 MB RAM onboard. I will try to solder BT module to FFUART again.

Ok i've got an OOPS with kernel panic "Aiee, killing interrupt handler! In interrupt handler - not syncing". I will check a backtrace.

If you didn't solder it to ffuart, how about running getty on ttyS0 and redirecting console output there?

The serial driver has some PXA270 dependencies, i.e. fifo size.
-albertr
[div align=\"right\"][a href=\"index.php?act=findpost&pid=95702\"][{POST_SNAPBACK}][/a][/div]

I've burned my ffuart so this isn't possible. I've changed FIFO size to 32 is there any other dependencies?

By the way: i've tried your desharpised serial driver? but it seems that it isn't designed to work with an old pxa. It isn't receiving any characters.

Umm... weird. Is it in BCSP mode? Can you see if kernel spits out any error messages? I.e. configure syslog to log everything out to console, make your current vt a console and run attach command from this vt?
-albertr
[div align=\"right\"][a href=\"index.php?act=findpost&pid=95698\"][{POST_SNAPBACK}][/a][/div]

Yes it's in BCSP mode. I can't see any kernel error messages since it's hangs so completle that even fb driver isn't working. Some times it doesn't hangs and all working very good until i relaunch hciattach. And this is happening at any speed even at 38400.

albertr, i need your help
It's seems that you know sharp's serial driver internal very well. After finishing all the soldering stuff i have a problem with software now. The problem is that when i run hciattach it initializing bt module and then after a second or bit less zaurus is fully, totaly , absolutely hangs. If i enable DEBUG stuff in the driver then it doesn't hangs but BT isn't working well.

I came across an advert for a company who sell embedded bluetooth modules...
http://www.adaptblue.com/wireless_tech_full_list.htm

the small one is only 13.5 mm x 10 mm x 1.9 m, but it probably needs some interface circuitry and external aerial.

meanwhile, I have a friend of a friend who works at CSR, so I am wondering if I can get hold of an engineering sample of a small module. I presume I just need to find one that has a 3.3V logic level serial interface that runs in 2-wire UART mode?
[div align=\"right\"][a href=\"index.php?act=findpost&pid=94676\"][{POST_SNAPBACK}][/a][/div]

Why don't  you want just use an USB dongle? It's small enought to fit it into zaurus and uses 3.3 v logic level.

The whole schematic should be a somthing like this:

Warning: transister connection is totaly wrong.

Ok.. If you turned external power on, the power LED is turned on and you will take bluetooth power on and all irda hardware down...
Is it ok?
[div align=\"right\"][a href=\"index.php?act=findpost&pid=94601\"][{POST_SNAPBACK}][/a][/div]

No. The power LED is controlled by kernel so we can track the moment when external power cord is connected and turn on the power LED twice quickly. The pull-down capacitor will not allow BT to be turned on during this procedure. The only place where we can't track the moment of applying  power is when device is in sleep mode or is switched off. But IRDA transiver is switched of at this moment too so this is not an issue.
