channel()

Description

Gets the WiFi channel of a network that was scanned.

Syntax

WiFi.channel(wifiAccessPoint)

Parameters

wifiAccessPoint - specifies from which network to get the information

Returns

WiFi channel of scanned network

Example

…
  // scan for nearby networks:
  Serial.println("** Scan Networks **");
  int numSsid = WiFi.scanNetworks();
  if (numSsid == -1)
  {
    Serial.println("Couldn't get a WiFi connection");
    while (true);
  }

  // print the list of networks seen:
  Serial.print("number of available networks: ");
  Serial.println(numSsid);

  // print the network number and name for each network found:
  for (int thisNet = 0; thisNet < numSsid; thisNet++) {
    Serial.print(thisNet + 1);
    Serial.print(") ");
    Serial.print("Signal: ");
    Serial.print(WiFi.RSSI(thisNet));
    Serial.print(" dBm");
    Serial.print("\tChannel: ");
    Serial.print(WiFi.channel(thisNet));
    byte bssid[6];
    Serial.print("\t\tBSSID: ");
    printMacAddress(WiFi.BSSID(thisNet, bssid));
    Serial.print("\tEncryption: ");
    printEncryptionType(WiFi.encryptionType(thisNet));
    Serial.print("\t\tSSID: ");
    Serial.println(WiFi.SSID(thisNet));
    Serial.flush();
  }
  Serial.println();
