Bearingless traffic not shown, but alerts for them are.

Before installing it in the aircraft, I am testing a TRX-2000 with airconnect and skydemon on ipad.
Airconnect is on the TRX-2000 port 2, and display bearingless traffic is enabled on this port.
For this‌ bench test, I put the TRX-2000 in simulation mode so it generates both traffic with bearing and without bearing that are potential collisions.
The TRX-2000 display shows the position of aircraft with a bearing on the screen with a symbol, the bearingless targets are show as a circle around my position. Skydemon shows the aircraft with a bearing on the screen correctly but those without are not shown at all, no circle or anything. However, skydemon shows an alarm when a bearingless aircraft is within the alert range, I have seen show approaches from 9 O'clock or 3 O'clock or 8 O'clock. For example, the alert will say "traffic behind 8 O'clock, 0.0 nm, Level".
‌The skydemon navigation option "show bearingless targets" has no influence on the behaviour.
Anyone with this set up has this experience?‌
Is this expected?
How would skydemon know where a bearingless traffic comes from?

Tim, I have a video of both screens‌‌‌‌ (100MB), let me know if you want it.

If you're using a genuine Flarm device such as that one, it generates the alerts itself and we simply display them. Our own collision detection code is not used. I therefore cannot comment on the situations in which Flarm would issue an alert (which we display).

I can however confirm that we show bearingless targets if the associated option is turned on, in fact we show them as circles in much the same way many Flarm displays do. In order to look into any non-showing issue you're experiencing we would need a data dump of exactly the data the Flarm device is sending to us when it's receiving a bearingless target but SkyDemon is not showing it.‌


Hi Tim,

I found time to log‌‌ the data sent to skydemon, will send you that directly.
