Linux: getCurrentConnections returns an array with the same element doubled

[zeved]

Sometimes the getCurrentConnections returns the same array twice inside the array:

[
  {
    iface: 'wlan0',
    ssid: 'Unknown SSID',
    bssid: '12:34:56:78:90:AA',
    mac: '12:34:56:78:90:AA',
    mode: 'Infra',
    channel: 36,
    frequency: 5180,
    signal_level: -50,
    quality: 100,
    security: 'WPA2',
    security_flags: { wpa: '(none)', rsn: 'pair_ccmp group_ccmp psk' }
  },
  {
    iface: 'wlan0',
    ssid: 'Unknown SSID',
    bssid: '12:34:56:78:90:AA',
    mac: '12:34:56:78:90:AA',
    mode: 'Infra',
    channel: 36,
    frequency: 5180,
    signal_level: -61.5,
    quality: 77,
    security: 'WPA2',
    security_flags: { wpa: '(none)', rsn: 'pair_ccmp group_ccmp psk' }
  }
]

Expected Behavior

The resulting array should not contain the same network connection twice

Current Behavior

The getCurrentConnections function returns the same network twice

Affected features

• [x] node API
• [ ] cli

Steps to Reproduce (for bugs)

Call the getCurrentConnections function repeatedly and analyze the result

Context

I am using your package in an NodeJS server for an Electron app and I need to poll the status of the Wifi connection every 5 seconds.

Your Environment

• OS: Debian 10.6 64 bit
• node-wifi version 2.0.14
• wifi card: Intel Corporation Comet Lake PCH CNVi WiFi
• node: 12.18.4

P.S.: I created two separate issues because even they are related (the same function) they are two different issues (or at least so they seem)

Edit: 'Unknown SSID' is the actual name of my Wifi, no error there :grin:
