Uni Edition. Bridge
Purpose of the UAT bridge is to receive ADS-B traffic information on UAT (978 MHz) aviation frequency,
then to re-broadcast the data using one of supported RF ISM band protocols.
Traffic information is re-broadcasted at very low power setting, so reception coverage is limited to a close vicinity of
the aircraft, equipped with the UAT Bridge. Other aircrafts nearby, such as gliders on the grid, have a chance to receive the information as well.
For the benefit of most of pilots, receiving device is not necessarily has to be one of SoftRF units.
Other make and models, such as OGN Tracker, PilotAware, FLARM (or, optionally, SkyTraxx) should also suffice.

2 - input of NMEA data from a GNSS source is required to operate over "Air V6" radio protocol.
Procedure of settings change is similar to that the Dongle has.
Settings description is located here.
Be aware, that within the Bridge use case - there are only two options that make sense, such as:
- Protocol, and
- Region
other settings will be ignored.
Default settings are: EU and OGNTP. While using these default settings the TI SensorTag is able to bridge UAT traffic into OGNTP 'out-of-the-box' - no extra hardware is required.
WARNING : UAT ADS-B protocol is typically reporting air traffic relative to barometric altitude while "Air V6", OGNTP, P3I and FANET protocols are using GNSS altitude for traffic resolution. Thus, pilots should be aware that actual UAT traffic can be higher or lower than reported.
