UnitV2 uart function switched to motion_tracker.

class14

How do I send a command to the UnitV2 to start motion_tracker?
Are there examples of this somewhere?

{
"function": "Camera Stream",
"args": ""
}

BUT Returns this

{"error":"invalid json format."}
{"error":"invalid json format."}
{"error":"Command is not supported"}
{"error":"invalid json format."}
{"error":"invalid json format."}

Can anyone help with this problem I have ? Please
{"error":"invalid json format."}

OR
if I send it this way

{"function":"Motion Tracker","args":""}

I get No response and no change to the mode. so it fails also. Just ignores the string no reaction. 2 Days in
