# ip link set can1 up
# candump can1 &

# #---- Can2 as sender ----# #
# ip link set can2 down
# ip link set can2 type can bitrate 1000000 dbitrate 2000000 fd on
# ip link set can2 up
# cansend can2 123##155

# #----If no error, the receiver will receive the following data----# #

See more details of the usage of “candump” and “cansend” :

Note:

1. Receiver should run before sender.

2. The “bitrate” and “dbbitrate” should be the same for sender and receiver
