是的，这个是不支持A3

我使用的是A3的飞控，用的OSDK3.9.0，
TopicName                 topicList1Hz[]                = { TOPIC_BATTERY_INFO ,TOPIC_HOME_POINT_INFO  };
  // Verify the subscription
  subscribeStatus = m_djiVehicle->subscribe->verify(responseTimeout);
  if (ACK::getError(subscribeStatus) != ACK::SUCCESS)
  {
        std::cerr << "Fail to verify DJI" <<std::endl;
        ACK::getErrorCodeMessage(subscribeStatus, __func__);
        return QGC_NG;
  }

  // Set the Info to get 1Hz
     numTopic = sizeof(topicList1Hz) / sizeof(topicList1Hz[0]);
  packageID = 0;
  freq = 1;//1Hz
  pkgStatus = m_djiVehicle->subscribe->initPackageFromTopicList(
        packageID, numTopic, topicList1Hz, enableTimestamp, freq);
  if (!(pkgStatus))
  {
          std::cerr << "Fail to Init 1Hz DJI Info" <<std::endl;
        return QGC_NG;
  }

  subscribeStatus = m_djiVehicle->subscribe->startPackage(packageID, responseTimeout);
  if (ACK::getError(subscribeStatus) != ACK::SUCCESS)
  {
        ACK::getErrorCodeMessage(subscribeStatus, __func__);
        // Cleanup before return
        m_djiVehicle->subscribe->removePackage(packageID, responseTimeout);
          std::cerr << "Fail to start 1Hz DJI Info" <<std::endl;
        return QGC_NG;
  }


结果每次都是在initPackageFromTopicList的时候出错。
topicList1Hz[]                = { TOPIC_BATTERY_INFO ,TOPIC_HOME_POINT_INFO  }; 当中去掉TOPIC_HOME_POINT_INFO的话，就一切正常。

看了一下OSDK自带例子当中关于TOPIC_HOME_POINT_INFO的用法，和我上面的差不多。
唯一区别是OSDK自带例子当中 虽然调用了 TOPIC_HOME_POINT_INFO 但是 最上层调用的地方 有 这么一句注释 only support for m210 V2
是不是A3不支持 TOPIC_HOME_POINT_INFO啊

是的，这个是不支持A3
