# Obtaining adjust filter rate notification This sample app demonstrates how client can notified to adjust the incoming message filtering rate. 1. Implement ICv2xThrottleManagerListener interface class Cv2xTmListener : public ICv2xThrottleManagerListener { public: void onFilterRateAdjustment(int rate) override; }; Copy to clipboard 2. Create a initialization status callback method bool cv2xTmStatusUpdated = false; telux::common::ServiceStatus cv2xTmStatus = telux::common::ServiceStatus::SERVICE_UNAVAILABLE; std::condition_variable cv; std::mutex mtx; std::cout << "Running TM app" << std::endl; auto statusCb = [&](telux::common::ServiceStatus status) { std::lock_guard lock(mtx); cv2xTmStatusUpdated = true; cv2xTmStatus = status; cv.notify_all(); }; Copy to clipboard 3. Get a handle to the ICv2xThrottleManager object // Get handle to Cv2xThrottleManager auto & cv2xFactory = Cv2xFactory::getInstance(); auto cv2xThrottleManager = cv2xFactory.getCv2xThrottleManager(statusCb); Copy to clipboard 4. Wait for throttle manager to complete initialization std::unique_lock lck(mtx); cv.wait(lck, [&] { return cv2xTmStatusUpdated; }); if (telux::common::ServiceStatus::SERVICE_AVAILABLE != cv2xTmStatus) { std::cout << "Error: failed to initialize Cv2xThrottleManager." << std::endl; return EXIT_FAILURE; } Copy to clipboard 5. Instantiate Cv2xTmListener auto listener = std::make_shared(); Copy to clipboard 6. Register listener if (cv2xThrottleManager->registerListener(listener) != telux::common::Status::SUCCESS) { std::cout << "Failed to register listener" << std::endl; return EXIT_FAILURE; } Copy to clipboard 7. Wait for filter rate adjustment notification void Cv2xTmListener::onFilterRateAdjustment(int rate) { std::cout << "Updated rate: " << rate << std::endl; } Copy to clipboard Last Published: Jun 24, 2026 [Previous Topic Setting verification load](https://docs.qualcomm.com/bundle/publicresource/80-PF458-1/topics/cv2x_tm_load.md) [Next Topic Telephony](https://docs.qualcomm.com/bundle/publicresource/80-PF458-1/topics/phone.md)
