The BlueFly needs a special hardware setting adjusted. To adjust usePitot send $BUP 1* to
the BlueFly via the normal manner (or tick the box in the BFVDesktop application). This
makes the BlueFly read this pitot sensor each cycle via I2C and adjust the sent data
appropriately. This will be described fully in the manual update; but in the interim note that
the LX mode sends the Indicated Airspeed when usePitot is set.
When the BlueFly starts up with usePitot enabled it immediately begins a pitot calibration.
This lights the red LED on the shield, then takes about five seconds of pitot data. The
differential pressure measured is averaged and taken to be zero airspeed.
You can trigger another calibration at any time by pressing the red button on the shield next
to where the normal BlueFly button protrudes. It is important that the pitot tube is in no
wind when the calibration is underway.
If you set usePitot, but the shield is not connected, the BlueFly will send an error message.
