Download for IBM Worklight V6.1.0 Fix Pack 2
IBM Worklight Interim Fix README for 6.0.0.2

APAR status

• Closed as program error.

Error description

• If an iOS device loses the GPS signal, the application may not
  be able to activate geofencing triggers upon future geolocation
  changes.
  
  Additional Keywords:
  Location,
  
  Worklight Versions Affected:
  5.x, 6.x
  
  Initial Impact: Medium
  

Local fix

• Re-start acquisition again in the failure callback, e.g.:
  
       var errorCallback = {};
          errorCallback.Geo = function(err){
                                  console.log("acquisition error:
  " + err);
  
  WL.Device.startAcquisition(options.policy,
  options.triggers,errorCallback);
          };
          WL.Device.startAcquisition(options.policy,
  options.triggers,errorCallback);
  
  This will retry to start acquisition again and again until the
  GPS is working again or a location has been set in Xcode.

  * PROBLEM DESCRIPTION:                                         *
  * After a location acquisition error occurs (especially when   *
  * setting simulated location in XCode to None) the acquisition *
  * terminates.                                                  *
