The ‘Connecting with GCS’ (http://ardupilot.org/antennatracker/docs/connecting-with-gcs.html) page point a possibility to connect using Bluetooth.
The ‘Mission Planner Bluetooth Connectivity’ (http://ardupilot.org/copter/docs/common-mission-planner-bluetooth-connectivity.html) shows that bluetooth is connect on the TELEM-1 port; the same that ‘Connecting with GCS’ use to connect the radio…
So, to use the Bluetooth connection, can I use other port (TELEM-2)? Or which other?
