Good afternoon Davis,

It seems that for someÂ*reason SkyEcho does not transmit ownship report or ownship geometric altitude as per GDL90 protocol...weirdly the UDP Monitor revealed no message with 0x0a or 0x0b in the header!

What puzzles me is that if I run the EasyVFR app it shows the correct current position (with phone internal GPS turned off) so SkyEcho seems to transmit its position but in a different way, possibly as a traffic report. (there are messages with 0x14 in the header that when decoded show SkyEchoxxx)

The only other messages received on the UDP port are 0x65 which I found to be ID messages but which do not contain the position and heartbeat messages..

Any ideas what else I can do?

Thanks,
Bogdan
