I have deployed an application on an HP iPAQ 114 classic. The app has worked well for several months, then one day it started producing the following error:
Failed to load stack driver
(BlueToolsWC.dll). Reason:  null
The software environment on the iPAQ is:
Windows Mobile 6 Classic
CE 5.2.1616 (build 18220.127.116.11)
CPU: Marvell PXA310
Memory: 57.86 MB
Bluetools stack: BT-PPC Version 1.8.0 build 7000
Copyright 1999-2006 broadcom corporation
I have already tried to copy in the app folder the various arm version of the bluetools dlls, but the application error remains.
I also have re-deployed the application.
The error occurred while the iPAQ was being used by the customer, not me, so I cannot be sure about exactly what was beign done when the app stopped working.
I have the "faulty" iPAQ and another, identical iPAQ where the app is running fine, with the same bluetools version.
Can somebody give me a hint about where to look ?
Thank you in advance.
