Hi there,  
I want to know how to subscribe to two or more distance sensors oriented in different directions on iris model in sitl\_gazebo. Currently, I can get distance information from distance sensor Ided as 0. The rest do not display infos as i tried through “rostopic echo mavros/distance\_sensor/\<sensor\_name\>”. Thanks in advance
