There are two versions of the CAN frame—CAN 2.0 A and CAN 2.0C B. CAN 2.0 A uses 11-bit identifiers (standard frame), and CAN 2.0 B uses a 29-bit identifier (extended frame).

In node-red-contrib-canbus I can read both 11 and 29 Bits, but I can not write in 29 Bit

To send the same data with a 29-bit message ID, use:

**./cansend can0 000007DF#020105** **(but the Result is only a 11Bit identifier)**

Can someone help me?
