I have an Arduino framework project where I need an ESP32 to act as an Accesspoint and also join a Multicast Group to communicate with other ESP32 nodes that are connected to the AP. The system is a collection of ESP32 nodes that communicate using Multicast. So far, I am unable to get both AT and STA operating on a single node. The STA nodes all work well when an external AP is used.
Previously I used the AT-Command firmware from Espressif on some ESP32 devices to build a similar system and was able to get a node working as AT and STA.
Is this possible with the ESP32 Arduino library?
Thanks.
You can see this tutorial :

They created an ESP32 web server in access point (AP) mode. There’s a video demonstration of ESP32 WebServer in Access Point Mode. In Access Point Mode the ESP32 creates its own wireless Wi-Fi network in this mode, similar to the one provided by your existing router. In access point mode, we don’t need to connect the ESP32 to a Wi-Fi network. In the Wi-Fi network it creates, the ESP32 Wi-Fi board can connect up to 5 devices.
Thank you for your suggestion, unfortunately it does not address the issue I face.
What is needed is is an ESP32 device acting as an Access Point also running code that allows the device to join and interact with a Multicast Group. There is no server running on the ESP32, just firmware that sends and receives Multicast Packets (UDP).
Again, thanks for taking the time to try and help.
