Connection ESP32-GATEWAY via LAN with micropython

[Gxy]

Hi,
if I load a micropython firmware compiled with IDF 4, I get an error in network module: module object has no attribute 'LAN'.
It works with firmware compiled with IDF 3.
But with firmware compiled with IDF 3, I have to use the version esp32-idf3-20190529-v1.11.bin, otherwise I get errno 16 when I use wrap_socket().
May I know if there is a recent version (compiled with IDF 4) where LAN works?

Thanks
