    The CANblue II units enables multiple CAN networks to connect wirelessly us- ing the Bluetooth Serial Port Profile (SPP). If two CANblue II units are con- nected, one unit acts as the SPP server and one as the SPP client. The units can act as server and client in different connections simultaneously, allowing more than two units –...

  • Page 10: Extended Ascii Protocol

    To configure and transmit Bluetooth CAN messages, there is an ASCII proto- col defined. There is also a binary format available for the transmission of Bluetooth CAN messages to permit a better data rate. CANblue II units always use the binary format for CAN messages transmitted between them.

  • Page 11: Behavior Of The Canblue Ii

    4 Behavior of the CANblue II Restore factory settings If there is a "Config" connection to the CANblue II, the device can be reset to the factory settings using the command "D SETTINGS_DEFAULT". Without a Bluetooth connection, the device can also be reset as follows: (1) Turn off the CANblue II.

  • Page 12: Bluetooth Transmission Behavior

    CANblue II in the ASCII or binary format, the CANblue II switches to the same format. If the CANblue II is in autostart mode and a handshake is carried out on the "Config" connection (see 4.6 Autostart and handshake), the device switches to the binary format.

  • Page 13: Automatic Stop Of The Can Controller

    This concludes the handshake procedure and both CANblue II units will now exchange CAN messages in binary format. Automatic stop of the CAN controller If there is no more SPP connection to the CANblue II, the CAN controller au- tomatically stops. CAN filter Messages received by the CAN controller can be filtered.

  • Page 14: Loss Of Connection

    „C FILTER_DISABLE“ (S.56) Loss of connection If a CANblue II has stored a Bluetooth MAC address, then for five seconds it will attempt to establish an SPP connection to that address. If the connection attempt fails, then a new attempt is always started after two seconds.

    You can activate batch mode by specifying a configuration file as the second command line parameter of CanBlueCon.exe. The file is read and the com- mands are sent to the CANblue II. The additional commands of CanBlueConfig are especially useful here, be- cause you can easily implement loops and other constructs with them.
