Needless to say: no 'real data' packet, even without filtering. Most of the (beacon) frames i receive, are those from my network (respectively also my neighbors), but only some from my scapy program. And there we're around ~7.000 beacon frames in the air for around 2 hours. Wireshark recognized this arp (who is xxx, tell zzz).īut after sending around 30.000 packets, the esp32 only received 30 beacon frames. And those packets definitly exist - for example, i send an arp to my second computer and opened wireshark.
I send randomly some (thousand) packets (arp, icmp, tcp and beacon frames) in the air. Maybe some (encrypted) data frames, but mostly (98%) beacons. But when turning the esp32 on, i'll mostly get only beacon frames. All of the packets will be saved on a sd card in a wireshark friendly hexdump. So there is no filter and i should receive everything. 336029668bĮverytime the esp32 receive a packet the callback function will be triggered and i check if the mac address in the packets match with the mac address in the filter (line 20), but for now i leave this column empty (see gist). I use the promiscuous mode of the esp32 to capture network traffic around me.īut i don't get all of the packets.
