I have a couple of GoPro's connected to a Smart Remote device. I am able to connect to the hidden wifi access point created by the Smart Remote. I want to observe the communication between the GoPro's and the Smart Remote. Is this possible? I mean to intercept the UDP packets which are exchanged between the GoPro's and Smart Remote?

You will need a program like Wireshark and a means of grabbing all packets going over the netwerk. An old-school hub is the easiest method of achieving this (all ports get all packets) but they are no longer sold now-a-days. Your best bet is either a managed switch on which you configure a sniffer port which receives all the packets from the other ports or to add a second network port to your PC/laptop and turn it into a man-in-the-middle device.

If everything is wireless, including the sniffer PC, then Wireshark is able to capture everything flying through the ether and you won't need to bother with a cabled solution. A quick hint from the linked wiki page:

When installed on Windows Vista or later (including Win7, Win8 and
Win10) with option "Support raw 802.11 traffic (and monitor mode) for
wireless adapters" selected, all the wireless adapters can be selected
in Wireshark so as to capture raw 802.11 traffic. In "monitor mode",
raw 802.11 packets (data + management + control) with radiotap header
can be see. Otherwise, only 802.11 data packets can be see. You can
enter "monitor mode" via Wireshark or WlanHelper.exe tool shipped with
Npcap.

Here's the direct link to the initial setup page: https://wiki.wireshark.org/CaptureSetup/WLAN

And here's a link that describes how to decrypt WiFi traffic. https://wiki.wireshark.org/HowToDecrypt802.11

Wireshark has some awesome manuals, wikis and tens-of-thousands of questions on StackExchange so I hope this answer gets you started.

  Actually I am already trying to use Wireshark. What I am doing right now is, on my laptop I connect to the smart remote. Then I connect the gopros as well to the smart remote. Next I start Wireshark in promiscuous mode. But I see only the data which is sent from the smart remote to my computer. What I need is to see the data transfer from gopro to smart remote and vice versa. What happens is, every device connected to the smart remote gets a dynamic IP. I can see the data between the computer and the smart remote. But other things? How to see the data?
