问题描述
我能够通过蓝牙（延迟时间为8秒）从OBD适配器接收车辆数据。 如何将延迟减少到1秒。目前，我需要获得速度和RPM。 我正在使用pires API（https://github.com/pires/android-obd-reader）
代码：
public void stateUpdate(final ObdCommandJob job){
final String cmdName = job.getCommand().getName();
String cmdResult = "";
final String cmdID = LookUpCommand(cmdName);
cmdResult = job.getCommand().getFormattedResult();
Log.d(TAG,"new cmdResult-->4-->"+cmdResult+"--cmdName--"+cmdName);
}
就像下面的日志：
