Get Roaming Status and Indication

How to get roaming status and indications

Please follow below steps to request roaming status and indication

1. Implement IServingSystemListener listener class

class ServingSystemListener : public telux::data::IServingSystemListener {
public:
ServingSystemListener(SlotId slotId) : slotId_(slotId) {}
void onRoamingStatusChanged(telux::data::RoamingStatus status) {
    std::cout << "\n onRoamingStatusChanged on SlotId: "
                << static_cast<int>(slotId_) << std::endl;
    bool isRoaming = status.isRoaming;
    if(isRoaming) {
        std::cout << "System is in Roaming State" << std::endl;
    } else {
        std::cout << "System is not in Roaming State" << std::endl;
    }
}
private:
SlotId slotId_;
};

2. Instantiate initialization callback - this is optional

auto initCb = [&](telux::common::ServiceStatus status) {
    subSystemStatus = status;
    subSystemStatusUpdated = true;
    cv_.notify_all();
};

3. Get the DataFactory and data Serving System Manager instance

auto &dataFactory = telux::data::DataFactory::getInstance();
do {
    subSystemStatusUpdated = false;
    std::unique_lock<std::mutex> lck(mtx_);
    dataServingSystemMgr = dataFactory.getServingSystemManager(slotId, initCb);

4. Check if data Serving System manager is ready

    if (dataServingSystemMgr) {
        std::cout << "\n\nInitializing Data Serving System manager subsystem on slot " <<
            slotId << ", Please wait ..." << std::endl;
        cv_.wait(lck, [&]{return subSystemStatusUpdated;});
        subSystemStatus = dataServingSystemMgr->getServiceStatus();
    }
    if (subSystemStatus == telux::common::ServiceStatus::SERVICE_AVAILABLE) {
        std::cout << " *** DATA Serving System is Ready *** " << std::endl;
        break;
    }
    else {
        std::cout << " *** Unable to initialize data Serving System *** " << std::endl;
    }
} while (1);

5. Register for Serving System listener

dataServingSystemMgr->registerListener(dataListener);

6. Get current Service Status

// Callback
auto respCb = [&slotId](
               telux::data::RoamingStatus roamingStatus, telux::common::ErrorCode error) {
   std::cout << std::endl << std::endl;
   std::cout << "CALLBACK: "
               << "requestRoamingStatus Response on slotid " << static_cast<int>(slotId);
   if(error == telux::common::ErrorCode::SUCCESS) {
      std::cout << " is successful" << std::endl;
      logRoamingStatusDetails(roamingStatus);
   }
   else {
      std::cout << " failed"
                << ". ErrorCode: " << static_cast<int>(error) << std::endl;
   }
};
dataServingSystemMgr->requestRoamingStatus(respCb);

7. Wait for request response and notifications
