Decode Promiscuous WiFi Packet

Postby bonchenko » Mon May 25, 2015 11:43 am

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 decode this packet offline? I want to make sure that these packets do contain IP and MAC address. I will work on how to implement the decoder once I am sure its available in the packet. I tried to use Wireshark -> Import Hex Dump -> use encapsulation type ranging from Ethernet, 802.11 Wireless LAN, 802.11 Wireless LAN with radio information.

I also attached the hex dump log here:

Also, does anybody knows whether if I can get IP address and MAC address of the packet sender from the packet that i get? I am afraid that the packet is not the full OSI layer packet.

Hi,

We only return the head of packet now, it doesn't contain the IP address.

Sorry for the inconvenience.

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?

Thanks for your interest in ESP8266 !

We don't get MAC and IP address in sniffer now ,so sorry for the inconvenience.
