Error: [string -unknown location]:?: Call failed. (simCallScriptFunctionEx on isRunning@HTC_VIVE) (Trinus)

[BorisBogaerts]

Hello Boris,

I'm using the phone with Trinus(an app let mobile phone become VR headset) to simulate the HTC VIVE. Everything works well until I run the example scene 'hello vr world' Steam VR is stuck in running vrepVIVE and V-REP prints out Error: [string -unknown location]:?: Call failed. (simCallScriptFunctionEx on isRunning@HTC_VIVE) What can I do to fix it? Thank you!

Kind regards Lily
