Hi,
I have some updates. I manage to work. I try the config procedure from another android phone and works like a charm.
Phone that not work: Nexus 5 and nexus 7 with android 6.0.1
Phone that work: Nexus 4 with android 5.1.1
The wio software was the same in all situations.
thank you for your help and hope this work to you.
bye
