Hi.
I have an mcp shield and arduino.
If i sniffing my ecu me7.5 i get some pids with many value who are send by the ecu every 50-100ms.
I try to send some message to me7.5 to get pid values who is not send automaticaly by ecu but without any result.
First question is if i initiate some protocol before send request from ecu on can?
Second, this is my message who i send on canbus and i'm waiting an answer, but ecu not respnd:
{0X7eDF, 0x02, 0x01, pid, 0, 0, 0, 0, 0};
pid can be 0x05 ..... all pid from standard obd2 pids
Thanks in advance from your help
