python - 如何嗅探 Wi-Fi AP 名称和关联设备

Question

我最近正在开发一个流量监控项目，该项目基于计算存在的 Wi-Fi 设备数量。我想要获取可用 AP SSID 以及连接到该 AP 的所有客户端设备的列表。基本上，我想获得如下信息列表:

Network-Name    BSSID    RSSI
    Client-Mac1 RSSI
    Client-Mac2 RSSI
    Client-Mac3 RSSI
Orphan Clients：
    Client-Mac4 RSSI

我希望这可以通过使用带有 Wi-Fi 适配器和 python 的树莓派来完成。如果不可能，我有一个 ESP 8266，可以将其链接到 Linux 机器/Arduino。

请发表您的想法，了解如何使用哪种类型的平台/库来实现这一点。如果能附上一些代码示例就最好了!

Answer 1

从 esp8266 示例复制 - ESP8266Wifi - WifiScan: 然后您可以使用串行连接将其发送到您的主进程

    /*
 *  This sketch demonstrates how to scan WiFi networks. 
 *  The API is almost the same as with the WiFi Shield library, 
 *  the most obvious difference being the different file you need to include:
 */
#include "ESP8266WiFi.h"

void setup() {
  Serial.begin(115200);

  // Set WiFi to station mode and disconnect from an AP if it was previously connected
  WiFi.mode(WIFI_STA);
  WiFi.disconnect();
  delay(100);

  Serial.println("Setup done");
}

void loop() {
  Serial.println("scan start");

  // WiFi.scanNetworks will return the number of networks found
  int n = WiFi.scanNetworks();
  Serial.println("scan done");
  if (n == 0)
    Serial.println("no networks found");
  else
  {
    Serial.print(n);
    Serial.println(" networks found");
    for (int i = 0; i < n; ++i)
    {
      // Print SSID and RSSI for each network found
      Serial.print(i + 1);
      Serial.print(": ");
      Serial.print(WiFi.SSID(i));
      Serial.print(" (");
      Serial.print(WiFi.RSSI(i));
      Serial.print(")");
      Serial.println((WiFi.encryptionType(i) == ENC_TYPE_NONE)?" ":"*");
      delay(10);
    }
  }
  Serial.println("");

  // Wait a bit before scanning again
  delay(5000);
}
