I have a problem with an ESP32 device configured as WIFI STA. I have intercepted the incoming WIFI packets esp_wifi_internal_reg_rxcb" but I only receive IP packets, not ARP or other packets.
I have tried in ESP AP mode and with esp_wifi_internal_reg_rxcb I can receive ARP and other packets but in STA mode I can't. I have been digging in the lwip source code and esp-idf framework source code but it is too complex for me. I understand the posible solution may not be supported or clever, or stop working in a future esp-idf release, etc.. It is ok for me at this point.
Thank you for any help! Antonio
