Ugh... In case you will be looking for a Class 2 dongle, I have a small writeup on Billionton Class 2 dongle here: http://www.iral.com/~albertr/billionton/

I've bought the same billionton class 1 dongle as that which i've used before and but it's completely different inside. It is based on BlueCore3-ROM chip and doesn't have UART traced on PCB. Image follows.

Yeah, BC2-Ext are getting hard to come by, since it's older and more expensive than BC3-Rom. Manufacturers (Billionton including) using different revisions based on parts availibility and costs. That's the reason I did that writeup on Class 2 dongles from Billionton.

I've just bought a new NONAME dongle. I was unable to find an old revision Billionton. Only v1.2. But it's seems that this noname dongle have the same design as billionton has.

It looks close to BC2-Ext reference design, but not exactly it. I think I had some problems with this design awhile ago switching it into UART mode. Were you able to switch it?

The only problem was is to suggest UART pins since its placed in different place but oscilloscope is allways with me

I have another porblem. After switching it to BCSP mode i can't access its pskeys anymore. BTW i've upgraded its firmware to 16.4, can this be a problem?

I don't have an o'scope, so that was a real problem for me. -albertr |

Do you mean 16.14? If so, I don't think it should be a problem, at least I don;t rememeber seeing anything like this in the bugs list/release notes for this version. You don't use a ram persistent store to temporary test your ps keys, do you? What I do here is writing new ps keys into ram and then rebooting the module to test it out. Once I'm satisfied with everything, I write it into flash to make permanent change. -albertr |

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.

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? -albertr |

Can you post some images of it? |

Ok. I figured out. At the first look (internet sites) there is no available modules for sale now. I'll try to call to a companies selling dell's notebooks and ask.
