推荐答案
那你真的想知道吗？
随着ELM327协议是相当容易的。您只需发送一个PID ASCII码，您将收到的ASCII答复。它是基于轮询。所以，你将获得1回答1请求。只要你不送，你不收。
With the ELM327 the protocol is fairly easy. You just send a PID in ASCII, and you will receive an answer in ASCII. It's based on polling. So you will receive 1 answer for 1 request. As long as you don't send, you don't receive.
