hi, I'm trying to develop an app wich uses SPP, i'm on an Acer n50 handheld running WinCE 4.21 with the Widcomm-Broadcomm stack 1.5.0 build 3601, what i want to do is unload the Widcomm stack and use the MS stack, my guess is that since the Widcomm stack is just a device driver it can be unloaded, at least for the time my app runs and then reload the widcomm stack, so my question is : is this even possible to be done?, if so what kind of tools would i need to accomplish this daunting task
thanks!

not sure but i suspect that the ms bluetooth stack is absent in roms made with the other bluetooth stacks
havent heard about anybody going from 1 stack back to ms bs
ROMs with BT stack don't contain most of core DLLs from MS BT stack. You can use PlatformBuilder and compile the missing DLLs yourself, edit the registry, etc. But this does not worth the effort. Widcomm stack is better and more stable than MS.
And you cannot dynamically unload one BT-driver and then reload the other one without the softreset.
:?: :?: :?: Why would anybody want the MS stack in favor of the Widcomm :?: :?:
MS stack has one advantage over Widcomm - its programming is done through windows sockets and you don't need to pay 1000$ for SDK.

Hi All
Is there anyway we can remove the MS stack from the JAMs and installl other drivers for it. ????
Have a look at the thread about the Bluesoleil stack. For the Widcomm stack, as far as i know, there is no method known yet.
Hello,
I know It may have been asked before,But i searching a lot and I couldnt find any thread which is mentioning that a BT stack Widcomm is available for mini with PAN support.What I could find was just Bluesoleil stack which is an evaluation version
no replies for long time. Nobody knows? :?:
No, the Widcomm stack isn't running on the Magician. The PAN profile is only supported by the Toshiba and Bluesoleil stack, which are working together with the Magician. The extension of the MS stack which you can find in another thread doesn't provide the PAN profile.
Hi all,
I am programming an OBEX bluetooth program for pocketPC platform, I see that there are different bluetooth stacks (Widcomm, Microsoft,...) on different pocket pcs, also I see that there are many ways to write OBEX bluetooth apps, either Winsock or using IObex COM objects and may be others.
My question is:
1. Do I have to write two implementtions to work with Widcomm BT stack and MS BT stack?
2. I am currently implementing BT functions using IObex COM interfaces, will this work on Widcomm BT stack??
3. any suggestions?
I hope to find some help here as usual
Thanks for your time...

I think your best options is to make two components, because Widcomm BT implementation is completely different of M$ BT stack.
Fortunately both SDK are available.

Thanks, dotfred, but if I have to do two implementations then where can find Widcomm BT stack SDK?? is it free to download? and what approximate percentage of PPC users use Widcomm BT Stack?
Any other suggestions guys?

I have a Widcomm that works on my XDAII (I can give it), but for the rest, I really don't know. Don't forget that both stacks can't be active at the same time on the device, so you have to play with the registry and soft reset to activate one or another.
The biggest problem with Widcomm is that the bt headset doesn't work.
And the biggest problem of M$ stack is the lack of PAN and the BT manager is useless.
I think you should try to do it first for M$, when you succeeded then do it/try it with Widcomm, but you need a device that has it.
Cheers,

ps.: for the sdk, here is an interesting article and a download link:

Hello,
Does somebody know if there is any HTC device that use the Widcomm BT stack instead of standard Microsoft stack?
Thanks,
Emil.

Unfortunately the Touch Pro 2/Tilt 2 does. Why in the world would you want it? Nothing seems to work with it.. Several of my programs that use bluetooth don't detect anything.
I'm writing a BT application and I want to be sure that it works also on devices with the Widcomm stack.
Maybe there is a wrapper for the Widcomm stack that let all BT applications be compatible with it?
Why the OEMs use this stack instead of Microsoft's?

Hi emilbergg
It's to do with the chip that they use for the device. The Broadcomm chip requires the Widcomm software. Essentially, it's a driver issue. Different chip, different driver. I'm guessing the choice of chip is made on a mixture of functionality and cost.

Anyone tried to install MS Bluetooth Stack?
I dont think you can just "install" a BT stack.... although I wish you could...
it is possible tbough with a lot of driver modifications.
For sure it will be required to cook the MS bluetooth stack into the ROM instead of just install, but many other parts of the rom are using the widcomm stack so it will be a big job.
Its a shame, because i found the sound via A2DP was better via the MS stack, and other users have found the widcomm stack unreliable with car kits or hands free headsets.
I think a better approach would be for a updated widcomm stack
whether they update the widcomm stack, or change it for MS, I don't care, I just wish HTC would hurry up and do it... so many people have problems with it.
I've tried and failed... The Leo and the Rhodium use different BT/Wifi chipsets that arent compatible with the MS BT Stack
Oh dear, that doesn't sound good.
Thank you very much for trying to do it anyway NRG.
