I see a lot of Bluetooth adapters OBD-II reading speed, temperature, etc. Does that adapter read from the CAN bus with standard broadcasting?

If read with standard broadcasting from the CAN bus, where can I find this standard table of broadcasting? I need the speed value address.

The OBD PID for speed is 0x0D. The below link gives all available PID's
