Set radio power of the device

Quick steps: Please follow below steps to Radio Power state notifications.

1. Get the PhoneFactory and PhoneManager instances

auto &phoneFactory = PhoneFactory::getInstance();
auto phoneManager = phoneFactory.getPhoneManager();

2. Check if telephony subsystem is ready

bool subSystemsStatus = phoneManager->isSubsystemReady();

2.1 If telephony subsystem is not ready, wait for it to be ready

If subsystem is not ready, wait unconditionally.

if (!subSystemsStatus) {
   std::future<bool> f = phoneManager->onSubsystemReady();
   subSystemsStatus = f.get();
}

3. Instantiate Phone

auto phone = phoneManager->getPhone();

4. Implement IPhoneListener interface to receive service state change notifications

class MyPhoneListener : public telux::tel::IPhoneListener {
public:
    void onRadioStateChanged(int phoneId, telux::tel::RadioState radiostate) {
    }
   ~MyPhoneListener() {
   }
}

4.1 Instantiate MyPhoneListener

auto myPhoneListener = std::make_shared<MyPhoneListener>();

5. Register for phone info updates

phoneManager->registerListener(myPhoneListener);

6. Implement ICommandResponseCallback to receive the status of setRadioPower API call

class MyPhoneCommandResponseCallback : public ICommandResponseCallback {
public:
   MyPhoneCommandResponseCallback() {
   }
   void commandResponse(ErrorCode error) override;
};

7. Instantiate MyPhoneCommandResponseCallback

auto myPhoneCommandCb = std::make_shared<MyPhoneCommandResponseCallback>();

8. Set the Radio power ON/OFF.

phone->setRadioPower(true, myPhoneCommandCb);

9. Command response callback is invoked with error code indicating SUCCESS or FAILURE of the operation.

MyPhoneCommandResponseCallback::commandResponse(ErrorCode error) {
   if(error == ErrorCode::SUCCESS) {
      std::cout << "Set Radio Power On request is successful ";
   } else {
      std::cout << "Set Radio Power On request failed with error " << static_cast<int>(error);
   }
}
