Services are not registered correctly if they are added too fast. The following code leads to incorrect registration of the services and in turn to the problem described above, that the wrong characteristic is read.

    for (const auto &serviceData : serviceDefinitions) {
        services.emplaceBack(leController->addService(serviceData));
    }

The following code leads to correct registration of the services. The correct characteristics are read subsequently.

    for (const auto &serviceData : serviceDefinitions) {
        services.emplaceBack(leController->addService(serviceData));
        std::this_thread::sleep_for (std::chrono::seconds(1));
    }
