Hi!
I know I can send 802.11 custom packets with wifi_send_pkt_freedom, and I'am using it without any problem. But what about receiving?. Yes, I can enable promiscuos mode, and filter by MAC address. Doing that is perfect for sniffing, but not for communication, because the ESP8266 won't ACK the packets and if I'am not sniffing and my ESP is the only receiver, it will make the transmitter to repeat many times the packet. Yes, I can send it like broadcast or multicast to avoid waiting for the ACK, but I'll missing the ACK/re-send functionality. In short I would like to put the ESP Wifi interface in monitor mode (which is not promiscuos mode) And yes, I can use ESPNOW, but for my application it wont suit very well my needs.
Thanks!
