    Description

       

       am posting this in  hope I can IDENTIFY  the problem .

      YES I just want to IDENTIFY   WHICH  component  / application or whatever is causing the issue.  I do not expect a solution....

       

      The attached link describes a problem with QT example "scanner" failing to pair SPECIFIC Bluetooth  device  due to "authorization " . 

       

      I can duplicate  such failure at will- using btscanner or my own code.

      It only works with "boom box"  Bluetooth device. It fails with "SPP". 

       

      Unfortunately the QT class used to pair has SPECIFIC option NOT requiring authorization.,

      It looks as  this "no authorization required " is not working correctly .
