停止 HAL 中的更新,并取消注册回调例程。调用 stop 后,HAL 必须将之前注册的回调视为无效。如果在没有先前的“init”的情况下调用 stop,此函数不应执行任何工作。

初始化接口并向 HAL 注册回调例程。成功调用“init”后,HAL 必须开始在其自己的阶段提供更新。
状态:GPS_MEASUREMENT_OPERATION_SUCCESS GPS_MEASUREMENT_ERROR_ALREADY_INIT - 如果已注册回调,但未进行相应的“close”调用 GPS_MEASUREMENT_ERROR_GENERIC - 如果发生任何其他错误,HAL 在返回此错误代码后预计不会生成任何更新。
