The library supports

• Sending and receiving J1939 messages
• Transport Protocol (TP) handling for multi-frame messages
• Address claiming

Only Classic CAN mode is supported, CAN FD is not supported.

Naming convention

Function calls in the Kvaser J1939 API all have names starting with j1939_, e.g j1939_create_channel(). Data type names start with J1939, e.g J1939ChannelParams.

To build an application with the Kvaser J1939 library the code needs to

#include <kvj1939lib.h>

and link with kvj1939lib.dll on Windows and with libkvj1939lib.so on Linux.
