Bluetooth GPS Receiver

[jsteele]

I have a new Ambeon Bluetooth GPS Receiver that I'm trying to connect to my T-40. When I bring it up it locates the Ambeon GPS Receiver but cannot identify any services on the device. The T-40 has the XP and the IBM stack installed and NOT the Micrsoft stack.

I've successfully connected this receiver to my Ipaq 6315 so I know the device is working properly. For some reason however the IBM Bluetooth stack does not locate any services on the device.

According the the "docs" for the device, the Ipaq configuration, and the manufacturer's tech support, this device uses the "SPP profile" for communications. Is there something special about this profile that is not supported in the IBM Bluetooth stack? Anyone else seen something like this? It's very frustrating when the Ipaq with Windows CE 2003 works first time and my fancy Thinkpad doesn't

Do you have XP SP2 installed? Indeed the SSP profile is supported. The following is all about bluetooth and XP

Yes, this has XP SP2. The only difference is the IBM stack.

I tried installing a Billionton USB Bluetooth adapter which uses the Widcomm stack on a Windows 2000 (SP4) machine and it located the GPS receiver and the SPP service first time.

It's looking like the IBM stack does not support the SPP profile?

I still think SPP must be supported in IBM stack, as it is the same basic thing that is used by with DUN , I do that to my V3 phone - works fine.

In the modems section of control panel, I have the bluetooth modem using the driver bthmodem.sys and linked to COM10. That is all needed by all the GPS application so I think that if you can get to the point where you have the this COM modem driver set, you are. Pehrhaps it can be created manually, not sure, there is a bunch of relevant registry entries that I can tell if you need. I have bluetooth III.

What I hope is working instead is the audio service as I was thinking getting a bluetooth headset to use with skype and x-lite but looks like there are problems there as well.

For what its worth the audio is working on my Thinkpad. I have both a headset and stereo headset/mike defined and working. I had DUN working at one point as a test. It's just that I can't get the silly thing to find any services on the GPS unit.

I'm still trying to get my GPS receiver working and have found something interesting.

I removed the IBM Bluetooth stack and installed the Microsoft stack. The MS stack found the GPS receiver first time! But, naturally there is a cost for this, the MS stack will not recognize my Bluetooth stereo headset.

I removed the MS stack and reinstalled the IBM stack. I say this as if it were simply; the entire reinstallation of the IBM stack actually is at least a dozen installs and reboots and several hours!!! Bluetooth is truly Plug-and-Play: plug it in and play with it for hours until it works!

Anyway, with the IBM stack installed it will not recognize the GPS no matter what I do; it finds the device but will not find the SPP service. The upside is that unlike the MS stack, the IBM stack supports the stereo headset.

This is what passes for standardization! Talk about frustrated, this is ridiculous.

I'm going through the same thing with my Holux GPSlim 236 GPS unit. It works fine with the MS Stack but no services can be discovered with the IBM Integrated Bluetooth III stack.

I supposed I could go to the MS stack since I don't have any devices that depend on the IBM stack. I'd just prefer to get it to work with the IBM stack since everybody says it's better than the former.

I guess I'll be sticking with the MS stack until someone can find a fix.

[jsteele]

Well, two incidents are certainly not conclusive, but it's beginning to look like the problem is the IBM stack.

Anyone have any idea how one gets Lenovo to address such a problem, if at all.

[jsteele]

I know that the conventional wisdom is to remove the MS Stack and use the IBM Stack. But is it possible to have them both running --- see problems above with devices supported in one but not the other. If they will cohabit, what happens thats so bad?

I recently, (Last 30 days), added a Global sat BT-338 to my T41...
Pairing the two was not without several failed attempts...
Turned on GPS...
Turned on TP bluetooth radio...
Open bt devices[control panel], under options tab / enable connection & discovery...
Under com ports tab;
(In my case), Com5 was detected [outgoinging]...
Com6 [incomminging] ...
Turn off discovery...

Works like a charm with MS streets & trips...

My GPS unit is found. In My Bluetooth Places, when I click "Find devices in range", it shows up as:

HOLUX GPSlim236
Unknown: Major(31), Minor(0)

It just doesn't discover any services to associate with it and thus, doesn't assign a COM port (which is all I need to get it to work with Streets and Trips).

My phone is recognized without a problem as has the following services:
Audio Gateway on LG VX8100
Bluetooth Serial Port on LG
Bluetooth Modem on LG VX8100
