Hello everyone, I have an Audi A4 B6 from 2001.  
On the hardware side, I’m using a Raspberry Pi (Raspberry Pi OS) and a KKL 409.1 OBD cable.

Using the kw1281test file from GitHub, I can read the measuring blocks in real time through the terminal from the instrument cluster, since it uses that protocol.  
I’m wondering if someone could help me figure out how to send that data to RealDash?

I tried using a TCP server, but I couldn’t get it to work…  
Thanks in advance for any help!

Use the ‘RealDash CAN’ protocol to send data from your custom device to RealDash:

[RealDash-extras/RealDash-CAN/realdash-can-protocol.md at master · janimm/RealDash-extras](https://github.com/janimm/RealDash-extras/blob/master/RealDash-CAN/realdash-can-protocol.md)

After implementing the protocol, create an CAN Description XML file that instructs RealDash on how to interpret the frames in incoming data:

Does it matter that my car doesn’t have a CAN-bus at all, but only uses the K-Line protocol?

No, if you are reading the data with your custom device and passing the information to RealDash using RealDash CAN protocol.

Thank you so much for the instructions, I managed to send the basic data to Real Dash…  
I still have the warning lights and so on left to do…  
Thanks again!
