I am trying to work with the WiFi.SoftAP class in arduino os an ESP32.
the problem lies in the IP address for the softIP access point.
i am requesting 192.168.2.1 via WiFi.softAPConfig()
- IPAddress ap_local_IP(192, 168, 2, 1);
- IPAddress ap_gateway(192, 168, 1, 254);
- IPAddress ap_subnet(255, 255, 255, 0);
WiFi.softAPConfig(ap_local_IP, ap_gateway, ap_subnet); is returning 192.168.4.1 as the IP address
the program and output below illustrates that behavior
Any help you can give will be highly appreciated
