Hidden Wi-Fi SSID

The CANlink® wireless 4000, if defined as a Wi-Fi® Access Point (AP), can disable the broadcast of the network SSID.
Clients can still connect to this AP, but they must know the SSID beforehand.

Also, when configured as a Client device, it is possible to connect to an AP with a hidden SSID (if that SSID is known).

Server Configuration

The device must be initially configured as a Wi-Fi® Server.

  1. Set 0x3000:0x1F [WiFi Hide SSID broadcast] to 1 (Enabled).

  2. Hidden SSID is only possible within a secure network, therefore, set 0x3000:0x04 [WiFi Authentication Type] to 7 [WPA/WPA2 Mixed] to enable it.

  3. Since WPA/WPA2 has been selected, a password must be configured in 0x3000:0x05 [WiFi Authentication Key].

The SSID will be hidden upon next boot of the device, and will remain hidden until either being disabled, or a Factory Reset is performed.

Client Configuration

No specific client configuration is needed in order to connect to an Access Point (AP) with a hidden SSID.

As long as the authentication 0x3000:0x04 [WiFi Authentication Type] is set to 7 [WPA/WPA2 Mixed], the correct SSID in 0x3010:0x1A [Bluetooth SPP MAC Address 1] will connect, independently of a hidden Wi-Fi® SSID.
