When we mention about elm327, the first impression may be it is a kind of OBD Code Scanners. So how much do you know about elm327? Do you taking full advantage of elm327?
In fact, ELM327 not only can obtain information from your vehicle, but also have other feathers. The ELM327 expects to
communicate with a PC through an RS232 serial connection. No matter how you physically connect to theELM327, you will need a way to send and receive date. All of the responses from the ELM327 are terminated with a single carriage return character and, optionally, alinefeed character.Using the ELM327 is not as daunting as it first seems. Many users will never need to issue an ‘AT’command, adjust timeouts, or change the headers. Characters sent from the computer can
either be intended for the ELM327’s internal use, or for reformatting and passing on to the vehicle. The ELM327 can
quickly determine where the received characters are to be directed.
One of features of ELM327 obd2 is that ELM327 is not case-sensitive, so the commands ‘ATZ’, ‘atz’, and‘AtZ are all
exactly the same to the ELM327. It seems a funny thing , isn’t it ? So do you take full advantage of this deatails of
elm327?
One other feature of the obd2 ELM327 is the ability to repeat any command (AT or OBD) when only a single carriage return
character is received.So you should be noted that the memory buffer only remembers the one command – there is no provision in the current ELM327 to provide storage for any more。
