Could not test Signal Composer and Low-CAN API

["ashwin vijaykumar" <ashwindv0@xxxxxxxxx>]

Hello All, 

I am using Raspberry PI 4 with MCP 2515 CAN Controller and AGL Koi v11.0.4 (built by enabling CAN in build/local.config - ENABLE_CAN="1"). 

After flashing the CAN-Enabled-KOI-image, I changed the boot/config.txt file and made the following changes.

dtparam=spi=on

dtoverlay=mcp2515-can0,oscillator=16000000,interrupt=25

dtoverlay=spi0-hw-cs

I can see CAN Messages in "candump can0"  in AGL sent from Vehicle Spy. 

 
I can see CAN Messages sent by AGL (HVAC - FAN Speed) in Vehicle Spy [Message ID  0x030].

Just I have just tested Engine Speed in Dashboard Application by sending the CAN Message with ID 0x3D9 by referring to file default-signals.cpp from application agl-service-can-low-level. It was not getting updated in the UI. 

For demo application, where can I find the CAN Message ID from AGL Koi. 

After thatI tried to bind afb-demon with either Signal Composer or low-can-service, both giving errors. The command and error log I am attaching the log below.

Where can I find the documentation or sources to configure a custom CAN ID to Signal composer? 

What triggers OnSignalEvent (ref: ValueSource.qml, agl-cluster-demo-dashboard)

Best Regards,

Ashwin
