    Chinese light fixture – LedZeal Malibu S400. This light uses an onboard STM32 MCU, and a wifi module, and can adjust light spectrum output on a schedule.

    However, the only way to control this fixture is with a clunky, and out-of-date smartphone app. I’m trying to dump any sort of communication with tcpdump and Wireshark.

    The thing is, even though the Wireshark host PC is set up as the wifi Host AP, I’m only able to capture the broadcast request and reply on port 50000, when doing a “scan” on the app. I can control the light, but no other packets are shown.

    I’m only filtering based on the wifi MAC of the light.

    Is there some explainable reason why I can control the light, but seemingly no packets are being exchanged?

    Are you 100% positive your NIC is in promiscuous mode?

    Can you see non-broadcast communication between other devices on your network?
