    Description

      Reading all descriptors and characteristic as part of the service discovery is very inefficient. Especially when the user already knows the exact service & char uuids he desires to interact with.

      This implies changes to QLEController::discoverServices() and QLEService::discoverDetails(). The public API needs rather limited changes abut the internal platform changes are significant

      • Android ~3w
      • Bluez (1w for DBus & 3-4w for custom GATT)
      • CoreBluetooth (1-2w)
      • WinRT (2w - legacy and new implementation)

      Time estimate assumes ObjectiveC simplifications (QTBUG-75348) being done
