I have a PEAK canbus adapter (USB) connected to my Linux box, access from Qt C++ program. While all works well, when I receive frames they are all SFF (11-bit) ID's. candumps are all 11-bit ID's. Even if I send EFF (29-bit) frames, it only shows incoming frames in SFF.
The same happens if I use candump, all frames show SFF ID's.
However, after I switched my laptop to Windows and ran PEAK viewer, and then back to Linux, suddenly my frames were all showing in EFF in candump.
Is there something I need to set (in Linux/ip command/qt c++) to force the adapter to use EFF mode?
