HI Skydemon.. 

I‌ know there are some OLD threads on these devices.. And one that also states that ADS-B (traffic) is only working in the US.. (and this is wrong!) - you can even check their spec.. It only concerns weather information which is US only (of course).

I‌ have a device - and it works perfectly in europe (and elsewhere in the world where I tried it)..

S‌everal very good (but pretty useless)‌‌‌ apps for both Apple and Android that supports this device - I would hope that you would consider it too?

T‌hat have a pretty easy to understand SDK available as well..

Really‌‌ hope you will take this up - would be so lovely to get ADSB traffic information in sky demon!

T‌hanks in advance,
J‌esper

There are many popular ADS/B receivers designed for the European market. I do not believe the devices you've mentioned here are among them. If they become popular we will of course invest the necessary development time into supporting them.
