Q & A

Q: Currently, Wi-Fi WPA/WPA2 mixed is in use. Is the transition to WPA3 being considered?

Not at this time.

Q: Can MAC address filtering be implemented to allow only one device connection at a time?

  • For Bluetooth connections, yes. The MAC address of the Server can be selected in the Client, and only that device will be connected to.
  • For Wi-Fi connections, not at this time.

Q: Filtering Mechanism: There is a CAN filtering mechanism available for CAN to wireless communication to reduce unnecessary traffic. Similarly, is CAN filtering from the wireless interface to the CAN bus supported?

No - all messages sent via wireless connection to the CLW4000 are forwarded to the CAN bus.
This direction should already contain relevant data only to reduce bandwidth.

Q: Locking Device Configuration: Can device configuration settings be locked from access by a wireless connection, or the CAN bus?

No, almost all CANlink® wireless 4000 settings are available for modification using CANopen by a connected peer.
Everything connected is considered trusted.

Q: Intrusion Detection: Is an intrusion detection system (IDS) implemented to monitor unauthorized access?

No. Everything already connected is considered trusted.
