How to change can bitrate to 125K?

When I try by:

ip link set can0 type can bitrate 125000 restart-ms 100

Cerbo responds:

RTNETLINK answers: Device or resource busy

Does anyone know where I can find the can configuration profile files? (eg "VE.Can & Lynx Ion BMS (250 kbit/s)", "CAN-bus BMS (500 kbit/s)"), if I find it I can edit it to 125Kbit/s.

According to the Cerbo manual:

You can configure the 250 kbit/s VE.Can port to 500 kbit/s (or one of several other CAN-bus speeds for other CAN-bus applications).

Regards.

@stanhausc I think you might need to ensure the interface is down to make the change. Try doing an ifconfig can0 down before the change. Then after teh change do an ifconfig can0 up.
