Problem ACK on tx error

[v0nHoFF]

Hi everyone! I try to configure the candlelight-FD on ubuntu 22.04 with 6.5.0-26-generic kernel and I still get the error no-acknowledgement-on-tx when I'm using the command to configure the interface from the original website (sudo ip link set can0 up type can bitrate 200000 dbitrate 2000000 fd on).

v0nhoff@v0nhoff-706M:$ sudo ifconfig can0 down
v0nhoff@v0nhoff-706M:$ sudo ip link set can0 up type can bitrate 200000 dbitrate 2000000 fd on
v0nhoff@v0nhoff-706M:~$ candump any,0:0,#FFFFFFFF -extA

The 7DF#0100 is the message that I've sent using the cansend program in order to start the communication between the car OBD port and candleLight-FD.

If you don't get an ACK, you're effectively alone on the bus or using the wrong bit rate. Note this is not a candlelight problem, I think you'll find better help in a CAR hacker forum.
