How to sniff UDP packets from tablet to wi-fi LED controller

0

Hello,

I have a wi-fi LED bulb controller that receives UDP packets from my tablet via wi-fi and then translates into RF signals.

I want to sniff the UDP packets sent from tablet to the controller via wi-fi (sniffing from the computer in the same network)

I am totally new to wireshark and somehow cannot get the settings right..

So for example tablet IP 192.168.0.102 is sending packets to controlelr IP 192.168.0.88 and I am sniffing from my computer (192.168.0.100).

When I select wi-fi as protocol, no extra settings, run the capture and try to do some traffic to the controller from tablet, I can see no packets with source 192.168.0.102

Any help would be appreciated

Best

If you want to capture Wifi traffic you need either a Linux system or a special hardware adapter on Windows systems (AirPcap adapter).

See the Wiki for a description how to capture Wifi traffic on Linux:
