@Lutz, thx for your help.
I´ve connected a SSH in PC while connecting TP-L to AQ and did "cat /dev/ttyATH0"
I saw chinnese simbols as you sugested (see image attached) .
I´ve tryed again to connec to N7 & N4 w/0 success.
Tried also to use in the qgc (setting/select interface/WLAN/address) 192.168.1.200:2002 no success.
