Hello Bob, thank you for kind replay.
unfortunately Parrot documentation on hblink3 is fragmented , a piece here, a piece there so a bit unconfortable to follow the puzzle
On my radio of course the parrot is a group call and I can engage the parrot, what is frustrating WAS the wrong audio coming back
I found another polish man talking about parrot on hblink3 and he says that first is necessary start the parrot service itself , otherwise no parrot service on board
that is my relative path.
Following the guidance to have a parrot.service , in facts, now the parrot is working succesfully
Was just the lack of a service
thanks again , 73's Marco IZ8XOH
