Can I use ForeFlight with a Garmin GTX-335?

The GTX-335 ADS-B Out transponder does not have bluetooth connectivity, so it can not connect and send data to ForeFlight Mobile.  The GTX-335 will work well in combination with a Stratus 2 or 2S; the GTX-335 provides ADS-B Out, while the Stratus 2 or 2S will let you view ADS-B In data in ForeFlight Mobile. Use with a Stratus 1 or 1S is not recommended because the Stratus 1 or 1S will not detect ownship.
