The format for a plain CAN message:
- {"bus": 1, "message_id": 1234, "data": "0x12345678"}
+ {"bus": 1, "id": 1234, "data": "0x12345678"}
**bus** - the numerical identifier of the CAN bus where this message originated,
most likely 1 or 2 (for a vehicle interface with 2 CAN controllers).
-**message_id** - the CAN message ID
+**id** - the CAN message ID
**data** - up to 8 bytes of data from the CAN message's payload, represented as
a hexidecimal number in a string. Many JSON parser cannot handle 64-bit
