Rakesh,

I've uploaded a change that adds the automatic vcan support that is in
agl-demo-platform to the agl-telematics-demo-platform image, you can try
cherry-picking it from:

https://gerrit.automotivelinux.org/gerrit/c/AGL/meta-agl-telematics-demo/+/25577

If you rebuild an image with that, it will automatically bring up can0 (or
whatever other interface is in /etc/dev-mapping.conf) as a vcan interface
if there is no hardware CAN present.  You can then drive some test
traffic by logging in and running "simple_can_simulator.py can0", which
will send vehicle and engine speed responses to the CAN binding's
diagnostic requests.

With respect to your telematics-recorder.conf, the MQTT section should
look like:

[MQTT]
broker=iot.eclipse.org
port=1883
keepalive=60

I would probably advise trying with a local instance of mosquitto at
first, it is easy to install and run on most Linux distributions, and if
you run it with "-v" you can see the incoming messages logged on the
terminal and know that things are working.

Scott
