[Ovmsdev] Scan and discover process for 29bits PID

Hi, Thanks to all the help you provide me here, I was able to identify most of the 11bits ECU with broadcast request and SavvyCAN, and relative PID with the PID scanner.I am a bit confused how I can scan ECU/PID with the extended mode (29 bits). How can I do the same kind of investigation and scanning with the extended mode ? Didier
