Hololens2 Not Visible in Tello Network

[SMRazaRizvi96]

The problem is that I want to send some TCP Packets from Tello to ROS. I connected my Hololens2 and the ROS system to Tello's wifi and both of them got connected successfully.

The problem is coming when I try to 'sudo nmap -sn my IP' to see the devices connected to the Tello's WiFi, everydevice is visible except the Hololen2. Because of this, I am not able to send TCP packets to my ROS system, which works through some other WiFi.

Please help.
