Set Up CAN Invader and UD100 Bluetooth Adapter for use with Python
Scripting.
L.Bellanca:
May 17, 2016: V3
Step 1: Download all the required sw to your PC. This includes:
-Download Python35 in file “python-3.5.1.exe” msi files do not exists for 3.5 branch. Note needs to be
32 bit version – 64 bit python does not work with PyBluez!!!
-Install to C:\Python35 directory – not the default location so you need to modify this during install.
-Make sure to select option to select the following as shown below and “Add Python to environment
variables” during the install setup.
-Then you need to download the correct PyBluez installer for 3.5 : “PyBluez-0.22-cp35-none-win32.whl”
-You may need to upgrade pip first : python -m pip install -U pip
-CD to directory where you downloaded the Pybluez whl file.
-To install, enter a command shell and type: “C:\Python35\scripts\pip install
PyBluez-0.22-cp35-none-win32.whl
Step 2 – Make Connections and configure files
-Connect the UD100 to your PC USB port and observe a solid blue light. Ensure device installs without
any errors as it should work with WIN7 with no other installs or downloads needed.
-Connect the CAN Invader to a powered diagnostic J1962 connector (aka vehicle or test bench)- observe
the solid green light and a blinking blue light on unit.
-Refresh your PC Bluetooth device list and look for a device called “OOBD – CIV – xxxx” and right click for
properties.
-You need to pair to the device with the PC first for the program to work. Enter the PIN code “1234” note 1234 worked for me but 0000 did not.
-Note that you may need to remove/delete device for list if you had it previously paired but then
allowed another PC to pair with it. So try deleting it if you are having trouble paring the device and you
have used the device before.
-Open the file “oobd_control.ini” and edit the MAC address in the file to match what shows on your PC
BT device properties for the unique identifier field:
-To set the default config file that is loaded on program launch, edit the file “ConfigFile.py” and ONLY
change the index number where indicated.
Step3 – Configuration and run program.
-Set the initial configuration file that is loaded when program runs by modifying the ConfigFIle.py file in
a text editor. Refer to file for instructions as this may change slightly in various releases:
-Verify the information in the xxxxx.ini file you selected. Refer to the example.ini file for information if
you need to modify anything.
-To launch program you double click on the file bg.py
-For beginner user, you can press the “Start Here” button to
connect and configure the CAN interface with 1 button press.
-For the advanced engineering mode, press “shift e” (capital E)
to show the engineering interface.
-You should then be able to verify the TP messages are being
sent and other commands as requested if you have access to a
CAN bus monitor ex Vehicle Spy or CANAlyzer
Overview of operation
The program bg.py has 4 primary functions:
1-Show graphical panel to user to allow triggering of functions, selecting of configurations, and general
system status information.
2-Start the server (tcpserver) to monitor for CAN requests over the BT interface. Initiate outgoing
requests to the server using pynetcat based on user actions.
3-Start and monitor another socket server thread that communicates over another port that is only used
for communicating with the Klippel program via batch file runs.
4-Define all of the communication functions such as the CAN messages needed to perform the tasks of
volume control, speaker control, VIN reading, bass/treble control, frequency setting and BT connecting.
General Usage
After BT dongle is connected to PC and CAN Invader is connected to vehicle, make sure the correct
configuration file is loaded. This can be chosen under the menu item “Configuration”.
User can also hard code the default configuration by editing the “Config.py” file in a text editor. File has
instructions for this.
1-Press “Start here” button – this will make connection via BT and set the default frequency, bass,
treble, check for AMP presence, and volume.
2-If a user wants to enable certain speakers, then press the corresponding label “Speaker xx”. Note that
not all vehicles will have a subwoofer or center speaker.
3-Use can also change the set FM frequency – note that the radio will need to be in FM mode for this
command to work. The bass and treble setting can also be changed is needed.
Klippel Integration
The gui panel can be controlled by running certain bath files. These files are:
The KlippelStartBT.bat file will invoke the “Start here” function.
The 7 speaker files will control the speakers as indication in title.
Possible need to add volume control?

This will open a java program used to interface with the CAN INVADER.
Press the Question Mark “?” on top header of program to set up the device COM port and script
directory.
OPEN QUESTIONS / TODO LIST:
1-Still not clear how the commands like “setVolume” and “SpeakerEnable” are translated into the
respective DID settings. I cannot find this library setting - must be in the OODB database somewhere.
ANSWER – these commands are defined in the file “b299mca_cancodes.py”
2-It would be desireable to have a way to change these settings:
1.
2.
3.
4.
5.
6.
7.
FM channel - always 87.90MHz?
Volume step is at 18~22 marks
Bass is at MAX
Treble is at Nominal.
Speaker Enable L r F R
Module ID for messages (x727 for AHU, x?DSP/AMP, x?ANC?)
Sending Message example:
Need to call : def sendCanData(self, seq, reqId=None, checkAnswer=False)
Step 1 – set the CAN ID:
self.sendCtrlSeq(["p 6 5 $"+reqId])
Step 2-send the message data
currentAnswer = self.sendRawData(data=command+"\r").decode("ascii")
Done with
oobd.sendCanData([command[3:]], checkAnswer=True)
Example From Comamnd line:
C:\python34\python.exe "C:\KTest\Klippel_Niehl_Final\OOBD_scripts\pynetcat.py" localhost 50000
raw12345678
Sends default ID 04 12 34 56 78 00 00 00
C:\python34\python.exe "C:\KTest\Klippel_Niehl_Final\OOBD_scripts\pynetcat.py" localhost 50000
raw12345678
Modified the tcp_server.py file for function “command[:3] == "raw": where you can now change the ID
in raw message format as follows:
raw12345678,7XX – will send message with new ID 7XX
raw12345678 = will send message with the default ID = 727 (or defined in ini file)
raw1003 = sends 727 03 10 03 00 00 00
raw1003,7DF = sends 7DF 03 10 03 00 00 00

Requirements for the BT CAN setup interface:
1-User needs to choose a setup/vehicle type using a PC screen
2-Once chosen, the correct .bat and .ini files will be selected for the script files.
Operation:
All possible files .ini and .bat files could exist in a \storage directory.
Once a vehicle type is selected, then the correct files are copied into the working directory for the
correct sequence of files to use.
Oobd_control.ini should be common by architecture – aka no plant changing SHOULD be needed.
Bat file could be dependent on the audio configuration and trim level and supplier of AHU.
Example seq:
0-BT interface self configures based on user input
1-Startserver for BT connection
2-Connect to BT/ configure CAN / Tester present ON
3-Radio On
4-Set Treb
5-Set Bass
6-Set Freq
7-Set Volume
Run Klippel Test
If fail, then
8-SetspeakerFR
