i am trying to modify the lwip to get additional functionality. However i am unable to pair my ESP8266 core version with lwip sources.
Here is what ESP returns by calling:
Serial.printf( "SDK: %s\n", ESP.getSdkVersion() );
Output:
SDK: 1.3.0
In this version, the lwip is stored in libraries/ESP8266WIFI - but there are no sources to compile, only headers and already built library:
How do i get the lwip sources for this ESP8266 Core version please?
Found it, recompiled it, tested it, works.
