You have mentioned about broadcast messages between ESP8266 and ESP32 not appearing unless they are on AP_IF.

I have noticed this today Sender ESP32 broadcast address broadcastpeer = b'\xff' * 6 e0.add_peer(broadcastpeer,ifidx=network.AP_IF)

Any broadcast sent from ESP32 on both the interfaces are not received by ESP8266, please confirm whether you are able to reproduce this and update the document accordingly.

Apparently this is a BUG in the underlying SDK and it appears to have been fixed in Arduino implementation, you may need to check with micropython team https://github.com/esp8266/Arduino/issues/6174

Just an update I have download the ESP-RTOS-SDK for esp8266 - an app built using that in C, can receive and send broadcast messages from ESP8266 it appears that the micropython team are using an older probably a non OS SDK which has bugs (including the DDoS loop hole) which is crashing my ESP8266 WiFi after 30 seconds of connecting (only to my router) a separate thread is going on regarding this on micropython discussion board .

I think they need to upgrade the ESP SDK on micropython

Thanks for following this up. This issue is noted in the online docs.

Yes, micropython uses the older non-os sdk for esp8266 and while that is the case there is not much I can do to resolve this issue. I'm not aware of any attempts underway tp adopt an updated SDK for esp8266 for micropython.
