What to know on which PORT my IoT device is connected

Actually, My college computer center agrees to open the PORT for connecting the IoT device. So please Help me to get to find port no.

Hi @ee21mtech14016,

Internet of Things devices has been using port 80 for a while now, including SOHO routers, TVs, gaming consoles, and ICSs. What are you looking for?

I want to connect the Bolt IoT device with mobile and make it “Online” with help of college wifi.

Thanks for your support. It got rectified.
