Torque can only talk to one adapter at a time
but if you are using different adapters for
different vehicles…

Pair each adapter to your device.

In Torque…

Create a vehicle profile for each vehicle
which specifies which adapter to use for
that vehicle.

I suggest using seperate dashboard layouts
so you can create unique pids, dashboards
and data logging for each vehicle.

Note that adapter settings should also be
selected to match your adapter type.
