Paolo,
From user prospective, installing a Bluetooth device on your PC is the same process on XPe as on XP Pro. This is true only assuming
the XPe image you've got is big enough and includes all the required components from Bluetooth stack as well as relevant GUI parts.
It sounds like the HP thin clients may not have all the components included (sorry, last time I played with an HP thin client was 3
or 4 years ago and they obviously evolved since then so I am not up-to-date with it).
I don't know what the T5720 is based on but it may or may not be running SP2 image (you better check this out at run time).
The proper way to resolve your issue would be contacting HP and ask them to provide a new image that includes the right (missing)
components. Otherwise all you are going to do is a hack and although technically possible but requires some knowledge of some XP
components.
If you are up for the hack, the first thing you should check is (make sure to log in as administrator on the device):
- if you plug in the Bluetooth device, does it get installed properly (check it out in the Device Manager).
- if didn't, check out if the image has all the relevant driver components such as CoInstaller and Device Class
Installer for the Bluetooth devices. Check out \windows\setupapi.log file to see what errors were logged in there.
- if it did, does the image include Bluetooth Control Panel applet? (check out Control Panel)
- if the CPL is missing, add it by copying from XPe Repository (or for testing purposes from XP Pro machine) to
your runtime along with all it static and dynamic dependencies (use DependencyWalker tool of Microsoft to explorer the binary).
