Wi-Fi settings

Access Wi-Fi settings, using ClosedDevice Configuration Utility Software tool used to set up data loggers and peripherals, and to configure PakBus settings before those devices are deployed in the field and/or added to networks. Also called DevConfig.. Clicking on a setting in Device Configuration Utility also provides information about that setting. These settings are available for data loggers with integrated WIFI modules.

Where to find:

  • All settings: Settings Editor tab in Device Configuration Utility: Wi-Fi tab.
  • Key settings: in Device Configuration Utility: Deployment > Wi-Fi tab.

See also Wi-Fi communications option

NOTE:

A list of Settings fieldnames is also available from the data logger terminal mode using command F.

IPAddressWiFi

Specifies the IP address for the Wi-Fi Interface. If specified as zero, the address, net mask, and gateway will be configured automatically using DHCP.

  • String data type

IPGatewayWiFi

Specifies the address of the IP router to which the data logger will forward all non-local IP packets for which it has no route.

  • String data type

IPMaskWiFi

Specifies the subnet mask for the WiFi interface.

  • String data type

WiFiChannel

This setting is only applicable when the device is configured to create a network (Configuration). It then specifies in which channel the network should be created. If Auto is selected, the device will use only channels 1, 6, and 11 to minimize interference from other networks detected in the area.

When manually selecting a channel, it should be noted that two Wi-Fi networks operating on the same channel will interfere with each other and will have to compete for bandwidth. The center frequencies of adjacent channels are 5 MHz apart and the bandwidth of each channel is 20 MHz which means that adjacent channels overlap. To completely avoid interference there must be a spacing of at least 5 channels between each Wi-Fi network. It is therefore recommended to use channels 1, 6, and 11.

  • Long data type

WiFiConfig

Configure the WiFi network. Join, create, or disable network.

  • Long data type, where:
    • 0 = Join network
    • 1 = Create network
    • 4 = Disable network

WiFiEAPMethod

The EAP Method must be chosen to match the EAP method being used by the Enterprise Security network. The inner EAP Methods supported are MSCHAPv2, MSCHAP, CHAP, and PAP.

  • Long data type

WiFiEAPPassword

If joining an Enterprise Security-enabled network enter password here.

  • String data type

WiFiEAPUser

If joining an Enterprise Security-enabled network enter user name here.

  • String data type

Networks

Lists the networks available in the area. Information listed for each network is shown as {SSID, RSSI / Signal Strength, Channel, Security}. Sometimes areas are covered by multiple access points configured with the same network name (SSID). In that case multiple unique access points possessing the same network name (SSID) may be listed here.

  • String data type
  • Read only

WiFiEnable

Set to enable or disable the WiFi service. By default, WiFi is enabled. To disable, set the Configuration option to Disable. 0 Disabled, 1 or <>0 Enabled.

  • Boolean data type

WiFiFwdCode (Forward Code)

This is an advanced setting to allow some customized filtering by the Wi-Fi module. It specifies which incoming packets are forwarded to the data logger. This decreases the amount of processing required by the data logger.

WiFiPassword

If joining a WPA or WPA2 security enabled network then this is where the passphrase is entered. If joining a WEP security enabled network then this is where the WEP key is entered.

If creating a network and a password is supplied, the network will be created using WPA2 encryption. The password must be at least 8 characters. If a password is not supplied, an open (unencrypted) network will be created.

When joining a network the device supports 64-bit WEP and 128-bit WEP. For 64-bit WEP enter a 40 bit key in the form of 5 ASCII characters or 10 hexadecimal digits (0-9, A-F). For 128-bit WEP enter a 104 bit key in the form of 13 ASCII characters or 26 hexadecimal digits (0-9, A-F).

  • String data type

WiFiPowerMode

This setting controls the power saving mode of the device. Regardless of the Power Mode setting, the device enables power-save mode when communications are not active. Power Mode determines how the device acts when communications are ongoing. This setting only applies when the device is configured to Join a Network using the Configuration option.

  • Long data type

WiFiSSID (Network Name)

The Network Name (SSID) is the name that identifies a wireless network (31 character maximum). The SSID differentiates one wireless network from another, so all devices attempting to connect to the same network must use the same SSID. If the device is configured to 'Join a Network', then enter the SSID of the network, including hidden networks, to join here. If the device is configured to Create a Network using the Configuration option, then the SSID entered here will be the SSID of the network created.

NOTE:

When creating a network, the device will not create the network if the Network Name (SSID) specified is the same as one that already exists in the area.

  • String data type

WiFiStatus

Specifies the current status of the Wi-Fi module.

  • String data type
  • Read only

WiFiTxPowerLevel

This fixes the transmit power level of the Wi-fi module. This value can be set as follows: Low (7 +/- 1 dBm), Medium (10 +/- 1 dBm), High (15 +/- 2 dBm). The value of this setting does not affect power consumption.

  • Long data type

WLANDomainName

The WLAN Domain Name is only relevant when the device is configured to create a network. When attempting to communicate with the device, attached Wi-Fi client devices can simply use the domain name specified here which will be resolved to the device's IP address. For example, the data logger web page can be accessed simply by entering the domain name specified here into a web browser.
