    • Team One Foundation Sprint 51

      Starting from 5.15.8 bluetooth reports an issue with connect when trying to access device characteristics e.g. in the lowenergyscanner example:

      QObject::connect: Cannot queue arguments of type 'QHash<QLowEnergyHandle,QLowEnergyServicePrivate::CharData>'
(Make sure 'QHash<QLowEnergyHandle,QLowEnergyServicePrivate::CharData>' is registered using qRegisterMetaType().)

      and no characteristics are found. The same problem does not occur in 5.15.7.

      Steps to reproduce the problem:

      1. build & start lowenergyscanner
      2. click search
      3. click on any device
      4. click on any service
