1. AP for initial configuration or reconfiguration of parameters for the STA access point.
2. STA for interacting with the program on a laptop via my home an access point.
I try to use mDNS to find ESP32 in the network, but it gives huge delays. I need to determine the IP address of the device in the STA network. What is the best way to find my device without using mDNS?
