Monitor connection change to local ad-hoc connection

[asafl1976]

Hi, I have an external device that is not connected to the internet but can be turned on as hotspot device so other devices (such as iPhone) can connect to it using Wi-Fi (same way like pulling media from GoPro camera). I'm trying to monitor a connection to that device (I know the Wi-Fi network name and device IP...) is there a way? Thanks
