It seems the IP/GW/NETMASK fields are configured using default values of
192.168.4.1
192.168.4.1
255.255.255.0when calling tcpip_adapter_init():
Environment
Problem Description
The platform works well with SDK just the problem is that the clients (Android phones and Windows Laptop) can't get ip from the board. They try to get IP but fail everytime. I can say that I tested with all the old versions of different ESP8266 SDKs (RTOS v2, IDF, Arduino). We don't see this symptom with all of them. But with new SDK (stable 3.x and master branch) the problem exists.
Expected Behavior
Getting IP from platform DHCP server in softAP mode.
Actual Behavior
Starts to print "tcpip_adapter: softAP assign IP to station,IP is: 192.168.4.2" It repeats this message for 4 or 5 times and them client leaves the WiFi. This will repeat and repeat again.
Steps to repropduce
Just build and run the softAP example from SDK.
