Unable to connect multiple VOXL2 mini drones to QGroundControl using different UDP ports

[Sarika Sharma]

I am trying to connect multiple VOXL2 Mini drones to QGroundControl (QGC) by assigning different UDP ports per drone, but I am unable to connect on any port other than the default 14550.

My Setup

Hardware: VOXL2 Mini
GCS: QGroundControl
QGC running on host PC

Goal

Drone 1

IP: 192.168.1.16

UDP Port: 14551

Drone 2

IP: 192.168.1.15

UDP Port: 14552

QGC successfully connects when using UDP port 14550 but not with 14551/14552

kindly look at the attached screenshots:

@Sarika-Sharma How are you setting up your network? Are you using WiFi? Station mode or AP mode? If you are using WiFi and station mode then you want to set the primary_static_gcs_ip of each drone to the IP address of the computer that is running QGC. Since each drone will have a different IP address you don't need to specify different UDP ports.

@Eric-Katzfey yes, I am using wifi and station mode.And I am able to connect multiple drones having different IP Address on the default 14550 UDP port .But I wanna ask can I specify different ports for each drone having different IP address???
For ex:
Drone 1 : IP->192.168.1.15 On port no 14551
Drone 2: IP-> 192.168.1.16 On port no 14552
