Hi,
I'm trying to use OAP in my audi A4 B7 with RNS-E radio.
Currently I'm struggling with can bus connection.
I have raspberry pi 4b 4GB with waveshare RS485 CAN HAT and wired it to RNS-E pins 9/10 like here
Raspberry is currently running under standard raspberry pi OS (once I get can communication I will install OAP so I will be able to control it with RNS-E factory buttons)
To get it working I mostly following those:

so my setup in config file looks like this:
I used following to start can
Also I installed can-utils to test can connection but unforcefully I'm not getting any other messages than this
Top part is result of running following script
https://github.com/skpang/PiCAN-Python-e...rx_test.py
and bottom part is result of running candupm but this message appears only when I powerup RNS-E when I click on buttons I'm not getting any messages
Anyone have any ideas what can be wrong?
Radio is working properly and shows radio station info on FIS.
Is there any test script in OAP which I can run?
