ON THIS PAGE
The networkconfiguration object allows for configuration of the network interfaces on the player. Each object instance corresponds to a single network interface (Ethernet, WiFi, or modem), which is specified using the type attribute.
This object only allows you to configure/retrieve settings related to the network interfaces on the device. For other network information, use the Node.js OS module.
Object Creation
To create a networkconfiguration object, first load the brightsign/networkconfiguration module using the require() method. Then create an instance of the networkconfiguration class using a string value that indicates the network interface associated with the instance.
var NetworkConfigClass = require("@brightsign/networkconfiguration");
var networkConfigEth = new NetworkConfigClass("eth0");
NetworkInterface
Use this interface to configure a network interface on the player.
getConfig()
Promise<NetworkInterfaceConfig> getConfig(NetworkInterfaceConfigRequestParams params[optional])
Returns configuration settings for the network interface. Depending on the specified type, this method will return an EthernetInterfaceConfig, WiFiInterfaceConfig, or ModemInterfaceConfig interface. If there is a set password, getConfig() will return true for the password parameter. If there isn't a set password, getConfig() will return false for the password parameter.
Note that this class concerns itself with the player's persistent network configuration. If you wish to determine the current settings (for example the IP address that has been retrieved via DHCP) then use the Node.js os module.
applyConfig()
Promise<void> applyConfig(NetworkInterfaceConfig config)
Configures the network interface using the parameters in the passed NetworkInterfaceConfig object. This method returns void upon success.
To reset a network-interface setting to its default value, pass the NetworkInterfaceConfig object without the corresponding attribute.
The config parameter should contain the complete desired configuration. Any previous configuration is overwritten. If you wish to change one item while keeping the rest of the configuration the same then first call getConfig and modify the returned object (see the example in the Examples section).
getNeighborInformation()
Promise<LLDPNeighborInformation> getNeighborInformation()
Returns LLDP information related to the network. This method is available with the ethernet interface only.
enableLeds()
Promise<void> enableLeds()
Enables or disables the ethernet activity LEDs (that is, flashing during link and activity behavior). Ethernet LEDs are enabled by default. Changes to this setting do not persist across reboots. This method is available with the ethernet interface only.
scan()
Promise<WifiAccessPointList> scan()
Scans for WiFi access points are returns a list of detected access points. This method is available with the WiFi interface only.
Attributes
[String] type: The network interface type, which can one of the following:"eth0": The ethernet port on the BrightSign player"wlan0": The internal WiFi"ppp0": A connected modem
Tip
The network interface can be configured as a VLAN using the following string format: "[parent_interface].[vlan_id]" (e.g "eth0.42"). Once the VLAN interface(s) are configured, they must be enabled on the parent network interface (e.g. "eth0") by including them in the vlanIdList of the parent interface. VLAN interfaces use DHCP by default. They are supported on Series 4 (XTx44, XDx34, HDx24, LS424) and Series 3 (XTx43, XDx33, HDx23, LS423, HO523) players only.
WifiAccessPointList
This interface represents the results of a scan for wireless networks. Each entry in the list contains the following parameters:
[String] essId: the WiFi ESSId network name[String] bssId: the BSSId of the access point[long] signal: The received signal strength. The absolute value of this attribute is usually not relevant, but it can be compared with the reported value on other networks or in different locations.
LLDPNeighborInformation
This interface contains location information received from the network infrastructure using the LLDP-MED protocol.
NetworkInterfaceConfigRequestParams
[bool] includeEncryptedSecrets:If set totrue, encrypted secrets are included, if set tofalsethey are not.
NetworkInterfaceConfig
This interface contains settings related to a network interface.
[long] metric: The routing metric for the default gateway on the interface. Routes with lower metrics are preferred over routes with higher metrics. If not specified the metric will be set to ensure that interfaces are preferred consistently for a given configuration.[DHCPServerConfig] dhcpServerConfig: A DHCPServerConfig interface that specifies the DHCP server configuration for the interface. The DHCP server can be disabled by setting this attribute to a null value when callingapplyConfig().[Array<String>] dnsServerList: A string list containing a maximum of three DNS servers. Each string should contain the dotted-quad IP address of a DNS server.[Array<IPAddress>] ipAddressList: An array containing zero or one static IPv4 address configurations. Players do not currently support more than one IPv4 address per interface or static configuration of IPv6 addresses. If the array is empty then IP addresses will be assigned using DHCP.[long] inboundShaperRate: If defined, the bandwidth limit for inbound traffic in bits per second. If undefined, there is no bandwidth limit.Note
Because of overhead on the shaping algorithm, attempting to limit the bandwidth at rates greater than approximately 2Mbit/s will reduce speeds to less than the specified rate.
[long] mtu: The maximum transmission unit (MTU) for the network interface in bytes. If not specified an appropriate mtu value will be chosen automatically.[Array<int>] vlanIdList: A list of VLAN IDs that this network interface is the parent for.[String] clientIdentifier: The DHCP client identifier for the network interface[String] domain: The domain name for the network interface[Array<String>] enabledProtocolList: An optional array containing the set of enabled IP protocols. The default value is [IPv4,IPv6].
DialUpInterfaceConfig
This interface contains attributes related to the modem interface:
[String] user:The username that has been entered. Whether the username is required varies between operators.[String] password:The password that has been entered. Whether the password is required varies between operators.[String] number: The "start connection" command, previously used to dial a number. Now,numberis almost always "*99#".[String] initString:The general modem setup string, which varies between operators.
DHCPServerConfig
This interface contains settings related to the DHCP server on the WiFi access point. This interface is only applicable if the player is using WiFi access-point mode.
[String] start: the beginning of the range of offered IP addresses[String] end: the end of the range of offered IP addresses[optional] [String] gateway:IPv4 address of the gateway to be used by clients.[optional] [Array<String>] dnsServerList: an array of strings containing the IPv4 addresses of name servers (IPv6 addresses are not currently supported)[optional] [String] domain:domain suffix to be used by clients

The following code applies a static IP address to the Ethernet interface. If a static IP address is not provided, it configures the interface for DHCP instead:
function main() {
process.chdir('/storage/sd');
var networkConfig = {
ipAddress:"10.0.1.20",
defaultGateway:"10.0.1.1",
subnetMask:"255.255.255.0",
broadcast: "10.0.1.255"
};
var networkConfigClass = require("@brightsign/networkconfiguration");
var networkConfigEthernet = new networkConfigClass("eth0");
var networkConfig = {};
networkConfigEthernet.getConfig()
.then(
function(data) {
console.log("=== Current config: " + JSON.stringify(data));
networkConfig = data;
if (networkConfig.dnsServers) {
networkConfig.dnsServerList = networkConfig.dnsServers;
}
if (networkConfig.ipAddress) {
// Use static IP address.
var ipAddress = {
family: "IPv4",
address: networkConfig.ipAddress,
netmask: networkConfig.subnetMask,
gateway: networkConfig.defaultGateway,
broadcast: networkConfig.broadcast,
};
networkConfig.ipAddressList = [ipAddress];
}
else {
// Use DHCP to obtain dynamic IP address.
networkConfig.ipAddressList = [];
}
console.log("=== Applying config: " + JSON.stringify(networkConfig));
networkConfigEthernet.applyConfig(networkConfig)
.then(
function () {
console.log("=== Success");
})
.catch(
function(err) {
console.log(err);
});
})
.catch(
function(err) {
console.log(err);
});
}
window.main = main;
The following code restricts IP version support to IPv4 only:
var networkConfigClass = require("@brightsign/networkconfiguration");
var networkConfigEthernet = new networkConfigClass("eth0");
networkConfigEthernet.getConfig()
.then(
function(data) {
networkConfig = {}
networkConfig.enabledProtocolList = ["IPv4"];
networkConfigEthernet.applyConfig(networkConfig)
.then(
function() {
console.log("Success");
})
.catch(
function(err) {
console.log(err);
});
})
.catch(
function(err) {
console.log(err);
});
To change one item while keeping the rest of the configuration the same, call getConfig and modify the returned object:
var NetworkConfiguration = require('@brightsign/networkconfiguration');
var address = {
ipAddress:"10.0.1.20",
defaultGateway:"10.0.1.1",
subnetMask:"255.255.255.0",

netmask: address.subnetMask,
gateway: address.defaultGateway,
broadcast: address.broadcast,
};
config.ipAddressList = [ipAddress];
networkConfig.applyConfig(config);
})
.then(function() {
console.log("Success");
})
.catch(function(error) {
console.log(`${JSON.stringify(error)}`);
