QLowEnergyService never completes discovery


  • I'm updating some old code that I wrote in QtQuick 5.8.0 for both android and iOS. I've recently updated to QtQuick5.11.1 and one of my QLowEnergyService objects never reaches the discovered state after I run DiscoverDetails() on iOS (works fine on Android). It also works fin for my other QLowEnergyService.

    I get a signal when it goes to the 'Discovering Services' state, but never get another signal for the discovered state. When I subsequently try to write a characteristic, it throws an operation error (as you might expect if it hasn't reached the discovered state).

    Has anyone encountered an issue like this?

  • I found a work around for this problem by reverting to Qt 5.10.2.

    Have you tried with 5.11.2? I'm thinking about upgrading from 5.10.1, but if this issue is still in 5.11.2 then there is no point.

  • Yes, it was still there. I will say that one of my services worked fine, it was just one service that wasn't working for some reason and this one only had an issue on iOS.
