BT-200 calibration

April 9, 2015 - 10:21am #1

We've tried to run Vuforia calibration application, but it won't start reporting "Failed to initialize Vuforia" error.

What could be the problem?

If you are getting a NoClassDefFoundError, it could be that libraries aren't getting included. Are you placing your projects in the samples folder of the 4.1.3 SDK? For example:

[vuforia sdk folder]/samples/DigitalEyewearImageTargets-4-1-3/

[vuforia sdk folder]/samples/DigitalEyewearVirtualButtons-4-1-3/

Hi, I'm trying to run samples DigitalEyewearImageTargers, and DigitalEyewearVirtualButtons and can't run both of them.

I'm attaching the log sample:

Thanks for the hint.

After enabling Internet connection the Calibration application works as expected.

A couple of questions:

  • Does your BT-200 have Internet connectivity when you run the calibration app?
  • What is the firmware of your BT-200?
