I am trying to simulate px4 sitl using gazebo. And qgc in my Android phone. Qgc and px4 are not connecting. Is it possible to do? Or am i missing something. Because px4 is running on one system and qgc on other.

It is possible, but you have to be in the same network. How are you configuring the network?

Hi, I have the same problem with connecting the gazebo by the Android qgoundcontrol.  
IP of the Ubuntu running gazebo is 192.168.1.104, and IP of the phone running Android qgroundcontrol is 192.168.1.103. They can ping to each other.

In qgroundcontrol, I add the TCP link of ‘192.168.1.104:5760’, then connect, but it fails and warns ‘Error on socket:Connection refused.’

if anyone has the same problem?
