MC33 crashes when using same driver Xamarin implementation as TC51

Hi,

We get a complete system crash, with a reboot, when trying to use the same driver implementation for MC33 that we built for TC51.

The crash only occurs when the scanner is initiated and the unit goes to sleep. When it's been sleeping for 3-10 seconds the unit just reboots. As long as the unit doesn't go to sleep the scanner, and the rest of the app, works just fine.

We tried using Microsofts "Insights" to log the crash to get some info, but it never sends any crash report.

Any help on how to debug this would be welcome.

Regards

Max
