BluetoothdiscoveryDemo does not find widcomm device

[Jov]

Hi,

my laptop has a widcomm bluetooth radio using broadcom driver version 5.1.0.4601 (for the Bluetooth Bus Enumerator device - btkrnl.sys). I am running Windows XP SP3. Bluetooth seems to work fine, I can also enumerate the devices with the Broadcom Bluetooth SDK.

When I start BluetoothdiscoveryDemo it does not find any radios. It just pops up a message box that says "Nothing found".

Any ideas?

Thank you

Hi,

If may appear because you don't have wcl2wbt.dll which is required when WCL works with WidComm. It is located in WCL\Redist folder.

Hi Mike,

I had already found a mention for that somewhere and checked if the DLL was loaded. To be certain, I copied it to the build directory.

I have included the loading sequence as running it under VS2008 shows it:

Hi,

Its a little bit strange. Could you please tell me more information about your laptop so I can download the driver version you use from official vendor site and check it here (I have only 5.1.0.1100 and 5.5.0.3200, would be great to test it with exactly your version)?

[Jov]

Hi Mike,

as far as I can tell, it is http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareDescription.jsp?lang=en&cc=be&prodTypeId=321957&prodSeriesId=3357377&prodNameId=3357378&swEnvOID=1093&swLang=13&mode=2&taskId=135&swItem=ob-57457-1 . The laptop is a HP 6910p.

I haven't installed this to see if this matches what is on my system but a version of this software is definitely installed. The driver date on the "Bluetooth Bus Enumerator" device is 20/11/2007 and the driver version is 5.1.0.4601. The "HP Integrated Module with Bluetooth 2.0 Wireless Technology" device is from 3/12/2007 and has driver version 5.1.0.4800.

[Mike Petrichenko]

Thanks a lot. I'll download it and test here. Will back to you with my result and possible fixes.

P.S. By the way, WCL includes 2 wcl2wbt.dlls: OLD and NEW. Try to use OLD (from redist\old folder) instead of NEW one used by default (they use different versions of WD SDK and the new one may not work correctly with old WD drivers).

[Jov]

That helped! I used the old DLL and now I can detect the device. "Connectable" and "Discoverable" show "Error 4" as column content though. Detected devices show "Error 40" as "RSSI".

[Mike Petrichenko]

Error 4 == WCL_E_FEATURE_NOT_SUPPORTED. WidComm doesn't support that properties.

Error 40 == WCL_E_NOT_CONNECTED: WidComm requires that device is connected to be able to measure its RSSI. WCL trys to simulate connection with enumerationg services on a remote device and try to measure RSSI during its enumerating. But its not good way because hard to "catch" the moment when device is connected. So the best way is connect to device and then read RSSI.

By the way, if you do not need Bluetooth 2.1 authentication (SSP) then you can simple use OLD wcl2wbt.dll - it works with ALL WidComm drivers version.

[Jov]

I'm not sure I can continue using the old DLL but for now, it'll do to get something up and running.

Thank you for your excellent support.
