pulkin / esp8266-injection-example Goto Github PK

Hi!

I'm working with esp8266 as sniffer to get Source MAC address, rssi and type from every packet received.

I read sniffer introduction document from Espressif library and I could see that exists a structure Sniffer_buf that contains other named RxControl where rssi is stored. However, when I get buf vector from wifi_promiscuous_rx callback, the first data in that vector is the packet, no RxControl, therefore when I cast vector to structure as pulkin do and I read sniffer->buf[4] to sniffer->buf[9] the MAC obtained is not address 1 but address 3 and sniffer->buf[10] to sniffer->buf[21] are not MAC addresses. I know that because I compare the packets with obtained through wireshark.

After that, now I know why sniffer->rx_ctrl.rssi values are always 0x80 or 0x08.

The question is: anyone know how this buf vector is organized? or anyone know any SDK (I am working with esp_iot_sdk_v0.9.3) that returns a structure type Sniffer_buf as wifi_promiscuous_rx callback vector?

Thanks in advance for your help.

I could compile your code with the latest opensdk and replaced the MAC Addresses with the ones of my AP and Client - it did compile successfully, however, it does not give any effect at all - Client and AP do still communicate. Did you use the esp opensdk? Did i do something wrong, maybe?

Is it possible sniff WPA handshakes with esp8266?

Hello,
I substituted the mac addresses and compiled/uploaded and when I start it up, the function wifi_send_pkt_freedom() always returns -1 indicating failure.
Do you have any pointers?

I'm using the esp-open-sdk (SDK ver. 1.4.0)

Hello all,
can anybody have any demo solution about getting mac address of station(clients) using esp8266 micro controller, I managed to get the data packet in sniffer (promiscuous)mode with the callback wifi_promiscuous_rx_cb, in my case what i impressed is to get the mac address of the client(smart-phones....)
And when i used the struct sniffer-buf vector to extract the mac- address it raised an exception error, i appreciate any kind of help please.
thank you

Hi there,

I've been doing a bunch of testing with my ESP8266 to try and get a better grasp of how everything is working. In your code you set the first two bytes for your deauth packet to 0xC000, but according to this page, I would expect the first two bytes to be 0x0C00 (the first two bits being used for the protocol version). Is this a typo in your code, or am I missing something?

Thanks!
