Stuffing Serial Bluetooth Module Inside C1k Casing

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]

Any news on your modifications? Am still champing at the bit. I am still thinking that a C3100 with the C1000 firmware and an internal CF bluetooth adaptor would be the coward's way out!
[div align=\"right\"][a href=\"index.php?act=findpost&pid=97447\"][{POST_SNAPBACK}][/a][/div]

Not yet... We've only had success with 128 Mb RAM and bluetooth for older models.
I think using 2nd CF slot for bluetooth would be a waste of vailable resource knowing that it's possible to solder a bluetooth module directly to serial lines

at the moment ou could use the IR line or the serial port on the back, i havent started to trace lines yet but there are alot of test lines on the board and there is the posability that the BTUART is used for testing on the production lines, otherwise there is always the USB port

Well, I was thinking that a 3100 with internal bluetooth or wlan in the CF slot would be a zero-solder low-risk option.
However, if my 860 could be turned into a bt-enabled 128MB ram device (and even fit more flash!), then I see no reason to upgrade! Snag is, who would be carrying out this work and how much would it cost? Have you got photos and details of the process?

Actualy I'm starting to think the same   My current "C760 on steroids" is almost perfect

The cost for the memory chips is about $100. The bluetooth module is spmewhat $20.

We took some pictures and will post them later.

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

and here is the a for the power control:

that's great news. I would guess that this mod should be quite relevant to the 860 as well?!
I've now got a 6000L, so I am thinking of buying two bluetooth modules from Segor.de, and following Guylhem's process of turning my 6000 into a 6000W, and then bluetoothing the 860 too!

amendment:
It wasn't clear whether you modded a 700,750 or 760. If a 760, then of course it's possible to  duplicate your work, but if you did the 750 then some interpretation is required.

also, how easy was it to find space to insert the bluetooth module?

thanks

This applies to any of the models: C700, C750, C760, C860.

The module is quite small, so it's not hard to find some space inside.

Cool pics, thanks!

I can't wait for someone to trace the lines on C1K/C3k/C3.1K pcb. Maybe there's someone with dead/burned pcb who wants to donate it for the sake of tracing the lines?

Well, this thread has been quiet for a while... Just want to post a quick update that I've just received some technical info (thanks to one of the long-time Zaurus community supporters!) and I hope it will give us some insight on how to trace lines on PXA270-based Zauruses. I'm not an electrical engineer, and I didn't have any time to investigate it yet, but it looks like BTUART lines are indeed traced on the PCB. I suspect the location where it might be traced to and will try to verify it soon. Even better than that, according to this information one of the USB host interfaces is traced on the PCB too! Stay tuned...

Great news! Please, keep us posted as we still plan to do hardware upgrades to CxK models, we just didn't have any spare time to spend on this.

This might have been mentioned already, but the following link was posted on Mobile Daily News yesterday:

http://www.piro.hopto.org/~piro/pukiwiki/p...%A2%B2%BD%5D%5D

Basically, someone took apart a USB BT dongle and stuffed it into his C3000.

This looks very interesting and promising!
However, I can only see the pictures and not read any Japanese!
What would be of interest to me:

* How to connect the BT module correctly to the USB port without making the USB port unusable for other devices?

* Where to connect the switch?

* Which kind of BT modules can be used (chipset...)?

thanks
