APSync on TX1 not connecting with Rover


I have a Pixhawk 2.1 and a Nvidia TX1 running APSync. When I flash the Pixhawk with Copter firmware, after changing requiered communication parameters on Pixhawk, I got connection between Pixhawk and Mission Planner through WiFi with no problem. But, if I flash the Pixhawk with Rover firmware, and also after changing all requiered parameters, I can´t get the communication with Mission Planner working.
Is there something else that needs to be configured on Pixhawk or TX1 to get it working for Rover?
