Yes, there is some smile.gif
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 smile.gif

And we have plans to solder 128 Mb of RAM to my C1000 too...

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

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

128 MB of RAM.

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

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.

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.

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

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

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 smile.gif
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.

QUOTE(speculatrix @ Sep 6 2005, 12:18 PM)
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?
*

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:

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?
*

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.

Umm, I wasn't thinking about using the same serial port for both bluetooth and serial connections. How that could be done?

It cannot be used for both bt and serial connections at the same time of course. But when BT is switched off a use of this serial port for other things shouldn't be a problem. However it may require some diodes to be soldered.

why not steal the IRDA serial lines? are they actually any use at all?

Yes. I'm using irda time to time. Not all of my friends have bluetooth enabled hardware.
But actualy we can share irda serial line with bluetooth.

I believe that charging LED control is only used in the kernel code.  I might be wrong, but it doesn't look like this LED is used in QT/Qtopia. If so, it shouldn't be hard to modify this code to blink twice or whatever.

If BCSP protorol is used, then I don't believe that power drain should be an issue. If serial driver would send break signal when port is closed, then BC will enter deep sleep mode where power drain is almost nil.
-albertr
*

But what if want to use your serial port for another things while BT is switched off?

I think we could mix speculatrix and mikekostousov solutions:
We can solder a JK flip-flop to the charge LED. To turn bluetooth on we just blink the LED one time. To switch BT off we must blink the LED once again. Then we must hook any access to the LED in kernel. So if any application is want to just blink the LED without turnin BT on we hook this and switching the LED twice very quick so it will not visible to user and BT does not switching on.

It's just a GPIO pin soldered to LED throught a PNP transistor. An one JK flip-flop is more than enougth to control the LED and the module separately

Yes we can. But what if you want to leave this LED for mail notification?

I don't use pskeys, but I believe it could be changed to use RAM store. Take a look at documentation available @ csrsupport.com.

On a side note, I recently acquired a DELL Trumobile 350 bluetooth module. It has a BC4-Ext w/ 8Mb flash inside and supports BT 2.0 specs with enhanced data rate (upto 3Mb/s). Even with slower uart speeds, the radio is supposed to transmit for shorted periods of time when communicating with other BT 2.0 devices, thus better power consumption.  It also small in size, so could be a good fit inside the Zaurus. However, I have a problem with locating its pinout (it has a 10 pin connector and six additional soldering pads on the back). The module is manufactured by USI for DELL, but all design is done by CSR itself, so I'm sure it could be switched to uart mode. Here in the US, it's just a slightly more expensive than usb dongles, I think I paid approx. $20 for this module. Can you find one in Russia at reasonable price?

I'm not fully understading what module a you tallking about. Is it a module use in Dell's notebooks? I'll take a look at prices. Can you post some images of it?

No i don't. I'm to lazy to write my own code for changin pskeys. So i'm using pskey provided by Fabrizio Gennari and it can't use a ram persistent store. Or maybe i had totaly mislooked something.
