FlightControllerState fcs = new FlightControllerState();
JSONObject jo = new JSONObject();

jo.put("系统时间", System.currentTimeMillis());
try {
    jo.put("是否启动", fcs.areMotorsOn());
    jo.put("是否飞行", fcs.isFlying());
    jo.put("无人机剩余电量", fcs.getBatteryThresholdBehavior());
    jo.put("累计启动时间", fcs.getFlightTimeInSeconds());
    jo.put("GPS卫星返回计数", fcs.getSatelliteCount());
    jo.put("GPS信号强度", fcs.getGPSSignalLevel());
    jo.put("IMU是否预热", fcs.isIMUPreheating());
    jo.put("无人机当前方向", fcs.getOrientationMode());
} catch (Exception e) {
    e.printStackTrace();
}

  使用的库是：

  import dji.common.flightcontroller.FlightControllerState;

  这个不是这么用的，要用fc.setStateCallback注册回调，然后在10Hz频率的回调里拿fcs。
