I think that the problem resides on the serial driver, because the X50 serial port and BT chip work at any speed with 2003 and only at 115.200 with WM5.
Also X50 Wm5 and X51 only works at 115.200 even with the MS Stack.

I think we have to write a new serial driver or to adapt a well-written serial driver from other PDA.

My results with a X51V running WM5 A06 with the widcomm stack are the exact same as the other X51V WM5 results. 9600 and 115200 are the only speeds that have an Rx packet.

Out of curiosity, has anybody tried replacing the serial driver with the one from another WM5 PocketPC with the same CPU (because as I understand it, the UART is on the CPU)

Installation question

I followed the instructions to replace the MS driver with the Widcomm 1.7.1 stack. I loaded PHM Registry Editor to handle the registry changes. I get to the next to the last step in the instructions, which is to "Execute Platform.reg". Here's where my problem is. If I open platform.reg, PHP launches, but I can't see what I'm supposed to do from there. I don't have the entries that are listed in the Uninstall section, so I think I'm not successfully executing platform.reg. How do I execute it? Thanks!

Answering my own posts-definitely a bad sign. I got the registry changed, but now I get an error message that the file BTTrayCE cannot be opened. There's another thread that talks about this problem, saying to power down and restart. I've done that, but the problem persists. I'm loading Broadcommx51v03 onto an X51V running WM5 version 5.1.70. What can I do to get the stack to work? Thanks.

Have you run SetSecurity to disable security prompt?

Yea, I did that. I went to the Bluetooth settings, since the tray icon wasn't there, and tried to turn Bluetooth on. The checkbox checked, but BT didn't work. When I went back to confirm that it was on, the checkbox was cleared. It wouldn't stay on. The good news is that I was able to restore the MS stack, and my devices (keyboard, mouse, GPS, phone) still work as before.

Speed problem solved

Thanks to a registry key found by MikelSpikel in BTCEStack.dll I've managed to make a patch that solves the speed problem.

Now the UART connects at 921.600bps that allows to get the 733Kbps that is the max speed for the data channel on Bluetooth 1.1 and 1.2

In fact I've seen speeds up to 52KBytes/s usinf file transfer between my computer and my X51v: 52KB x 8 Bits= 416kbps that with the overload of the file transfer is near the 733 Kbps and almos six times the previous speed.

Now I need your help for testing the patch and the new speed in different profiles, and specially, to test the A2DP Stereo Audio Profile that cam work at this speed.

To install the patch, simply import this registry file.

Hey beemer, thanks for the update, will try it momentarily. My question is, will this allow me to use a headset, or will I simply have to find out on my own? :)

I think someone who has managed to get their headphones working before but heard the helicopter noise should be the ones to try this. If that works then we can develop a list of known working headsets.

Mikelspikel, I PMed you this, but I thought I'd post it here too.

My Specs: X51v with A06, widcomm stack 0.35 upgraded to 0.36, Logitech Bluetooth Headphones.

My A2DP works now without any skipping. However, there is some noise and occasional clicking sound in the audio. If I had to compare it with something, I'd say it sounds like the artifacts and quality loss you get with heavy compression. However, it isn't quite like compression artifacts, because some instruments and parts of songs come through more clearly than others, and some instruments sound perfect with absolutely no quality loss or artifacts.

Is it possible that the quality issue is due to frequency limiting, because it sounds like it only affects certain frequencies?

It is bearable though and I am very pleased with the result!

Thanks to everyone involved in the development, you have all done amazing work and it is really appreciated.
