Frequently asked questions
Will this board work with Linux SocketCAN?
Candlelight-compatible firmware is recognized by the Linux gs_usb driver, which exposes the device as a SocketCAN interface. Check your kernel version and bitrate settings.
What should I be careful about when connecting to a vehicle?
The OBD-II port gives access to the vehicle's CAN network. Only transmit frames if you understand the vehicle's network, since incorrect messages can affect vehicle systems. Avoid active transmission while the vehicle is in use.
