Using Request Network Selection Mode API

Using Request Network Selection Mode API

Please follow below steps to request network selection mode

1. Get phone factory and network selection manager instances

auto &phoneFactory = telux::tel::PhoneFactory::getInstance();
auto networkMgr
   = phoneFactory.getNetworkSelectionManager(DEFAULT_SLOT_ID);

### 2. Wait for the network selection subsystem initialization ###

bool subSystemStatus = networkMgr->isSubsystemReady();

### 2.1 If network selection subsystem is not ready, wait for it to be ready ###

if(!subSystemStatus) {
   std::cout << "network selection subsystem is not ready" << std::endl;
   std::cout << "wait unconditionally for it to be ready " << std::endl;
   std::future<bool> f = networkMgr->onSubsystemReady();
   // If we want to wait unconditionally for network selection subsystem to be ready
   subSystemStatus = f.get();
}

### 3. Exit the application, if SDK is unable to initialize network selection subsystem ###

if(subSystemsStatus) {
   std::cout << " *** Network selection subsystem ready *** " << std::endl;
} else {
   std::cout << " *** ERROR - Unable to initialize network selection subsystem" << std::endl;
   return 1;
}

4. Implement response callback to receive response for request network selection mode

class SelectionModeResponseCallback {
public:
   void selectionModeResponse(
      telux::tel::NetworkSelectionMode networkSelectionMode,
      telux::common::ErrorCode errorCode) {
      if(errorCode == telux::common::ErrorCode::SUCCESS) {
         std::cout << "Network selection mode: "
                   << static_cast<int>(networkSelectionMode)
                   << std::endl;
      } else {
         std::cout << "\n requestNetworkSelectionMode failed, ErrorCode: "
                   << static_cast<int>(errorCode)
                   << std::endl;
      }
   }
};

5. Send requestNetworkSelectionMode along with required function object

if(networkMgr) {
   auto status = networkMgr->requestNetworkSelectionMode(
      SelectionModeResponseCallback::selectionModeResponse);
   std::cout << static_cast<int>(status) <<std::endl;
   }
}

6. Receive callback for get network selection mode request in selectionModeResponse function
