Peace be upon you. I’m requesting assistance in clarifying the process of sending a frame. Is there anyone in this forum who is an expert and can explain how to send a frame with illustrated examples or a video tutorial to make it easier for everyone to understand how to write XML and how to send a frame to a vehicle?
Review the topic on this page

CAN to RealDash
or RealDash to CAN ?
RealDash to CAN
i need send button on /off switch from RealDash : example Hazard Switch
and very thanks Falcon for quick answer to my.

This is what i use for mines. Also running off arduino. Maybe thus example will help
