Re: Decode Promiscuous WiFi Packet

What do you mean by head of packet? How can I get MAC and IP address from the sniffed packets? Any plan to include this or maybe what should I do so I can get the IP and MAC address?

Decode Promiscuous WiFi Packet

Hello, I am using ESP8266 to act as a logger to find devices that are using my LAN network. I can get this module to sniff wifi packets promiscuously, but now I need to decode the raw packets so that I know the IP and MAC address that are using my network. My question is, is there any method to deco...

Re: WIFI-SNIFFER EXAMPLE ON ESP SDK

Hi there. I tried your code and use SDK v1.01, but still not entering the sniffer rx promiscuous callback. Then I change the mode to station mode, previously you use stationap mode ( wifi_set_opmode(STATION_MODE); ) and now I can get the packet :D :D One more thing, can I get the IP adress and MAC a...

Access ARP cache in ESP8266

I learned that ARP cache should exist in ESP8266 since it is part of the link layer of internet protocol - it is needed for a device to send packet to other devices in the network. So maybe the question: can I access this ARP cache via ESP8266 SDK?

WIFI-SNIFFER EXAMPLE ON ESP SDK

Hi, anybody tried the wifi-sniffer example on ESP SDK 0.9.5? I compiled and flashed the fw to my ESP-01 but I cannot see any packet being sniffed. This is the UART output, http://s13.postimg.org/45wr655o7/log.jpg Also, after several minutes, it will behave strangely - wdt triggered but not restarted...
