PC CAN Interfaces (Bluetooth) - FAQ

FAQ Bluetooth - PC CAN Interfaces

• Q: How many CANblue devices can be connected?
  The VCI V2.16 can support 100 CAN Interfaces. But maximum seven CANblue can be operated at the same time, because the USB-to-Bluetooth Adapter (Bluetooth Stack) supports not more than 7 Bluetooth devices (CANblue) at the same time.
• Q: Do all CANblue run with one COM port?
  For each CANblue an own virtual COM Port is configured. The Widcomm Bluetooth Stack can configure maximum 8 virtual COM Ports. In the IXXAT Interfaces Applet COM Ports can be selected from COM 1 to COM 10.
• Q: How can I determine the status of the connection between the CANblue and the PC?
  The VCI V2 does not provide a function to determine the connection status of HotSwap devices.
  About 80 seconds after disconnection of the CANblue, you will get a dialog-message, which tells you that the CANblue does not respond and that the connection has terminated. The function "VCI_ReadBoardInfo" will return an error code after that.
  The VCI V3 will provide special functions to get the connection state of the HotSwap devices.
• Q: Which frequency band is used by the CANblue?
  Bluetooth and WLAN (11Mbit & 54Mbit) both work with the frequency of 2,4GHz. The use of Bluetooth and WLAN (11Mbit & 54Mbit) at the same time may cause disturbances/interactions, that can reduce the Range and performance of Bluetooth and WLAN.
• Q: Does the number of used CANblue devices influence the performance?
  The performance will be reduced because the devices share the band width.
• Q: How can I set the COM port number higher than COM10 in the IXXAT Interfaces applet?
  The COM port number can be changed in the Windows registry directly.
  Install the CANblue as described in the VCI installation manual, using e.g. COM port 10.
  Open the registry with "start | run" and enter "regedit"
  Change to the registry folder "HKEY_LOCAL_MACHINESOFTWAREIXXATHW" and
  look for an entry "CANblue" below any folder with a number.
  Modify the value of the entry "COM-PORT" to the value appropriate to your system.
  
  ATTENTION! The value is represented as HEX value. Change the "INFO" value according to the "COM-PORT" setting. This value is represented as string and is displayed in the "Select Hardware" dialog.
• Q: How can I deactivate the message box "IXXAT Driver Message: Device is not responding..."?
  "IXXAT Driver Message
  Device is not responding, device maybe disconnected?
  Please make sure the device is responding and
  start your application again!"
  
  Please set the registry entry
  HKEY_LOCAL_MACHINE | SOFTWARE | IXXAT | HW | xxxx | DISABLE_HEARTBEAT_TIMEOUT_DIALOG to 1.
  
  (The "xxxx" in the registry path is for the number,
  that was assigned to the CAN interface (CAN@netII/VCI or CANblue/VCI) during the installation.)
  
  It is possible to check the Ethernet connection state by calling the function VCI_ReadCanInfo cyclically (each 0,5sec.). If the Ethernet connection is broken, the VCI_ReadCanInfo returns the Error Code 0, and the exception handler reports an error message.
