Microsoft Bluetooth stack can't be found

[BrianG]

Detection of my other phone (Motorola Q) worked fine last time I tested this, but suddenly stopped. I try a scan for new devices (for the heck of it to test the system) and I get the error below. Last time I had that error, I tested the Microsoft scan, and saw that it had problems, but this time Microsoft can find the device, no problem.

Any ideas?

This is a message from the Bluetooth library...

If you are 100% sure you didn't deactivate bluetooth on your computer, you may want to try the updated version of the bluetooth library I just posted here:

I fixed this particular problem by uninstalling all bluetooth and rebooting the PC. then I updated the bluetooth tools.

With that problem gone, now I think I have found a bug. Scan for new devices only seems to work once, the second time it hangs for me every time.

[stipus]

OK. I'll have a look at this problem.

With some BT stacks, I may need to pause current discoveries before I start scanning, as I have done in the Bluetooth client for last release.

[BrianG]

Not critical of course, I reboot Homeseer and then it works fine.

thanks

Ok, now all my devices are away and stay away. If I run bluetooth discovery on the computer (I am careful not to add them) it finds all three devices just fine. However the plugin does not.

I did a scan, and got this error, not sure if related:

12/2/2007 5:03:10 PM - BT Debug - Error while polling MYPC: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

Ok, to help figure out the problem.

1. Rebooting doesn't help.
2. Changing network to "AutoDiscovery" then finds my laptop, but not the two phones.
