Downloading and using the app

Please download the app via here.

To get started, power on your GL.iNet device and launch the mobile app.

Customize the app's language by accessing Settings (upper-left corner) and choosing from available language options.

Tap the Scan button (upper-right corner) to scan the device in the current mobile network environment. Devices that have not been initialized will be displayed in the Bluetooth scan list. Initialized devices will be displayed in the LAN scan list (the current mobile phone and the device must be in the unified LAN).

Initialize a device

In the Bluetooth scanning device list, select the device you want to initialize to enter the network configuration page. The GL-S20 supports both wired and wireless network configurations. For details about network configuration, see the Internet chapter.

After the network configuration is completed, tap the button at the bottom of the screen to proceed to the administrator password set up page. The administrator password must be set with a minimum of 10 digits and a maximum of 31 digits.

Password requirements: Uppercase letters, lowercase letters, numbers, and symbols. You can enter letters (case-sensitive), numbers, and symbols (!@#$%^&*()_+-=,.><|? /[]{}:;”’ `~). Please submit it when you have set it up. Please adjust your phone to your device's current LAN, tap the scan button in the upper-right corner, find and selectyour device from the list.

Sign in to the device

Select the device you need from the list of LAN devices. Enter the administrator password that you just set, then tap Login.

Internet

In the bottom navigation bar, tap Network.

After you log in successfully, you can configure network-related settings here.

Failover

Failover is designed to monitor the network situation. It checksthe connection status of the destination IP address to determine whether the network is available.

Select the interface status detection mode to monitor and configure ethernet and repeater Wi-Fi. It supports the setting of IPv4 and IPv6 addresses.

By default, the system gives ethernet the highest priority. If ethernet connectivity is lost, it will automatically switch to an available Wi-Fi network. When Wi-Fi is not available, it automatically switches back to ethernet.

Note: To ensure system stability, when Wi-Fi is in use, the device will not automatically switch back to ethernet even after it is restored.

Ethernet

The Ethernet section displays information about the current network status. You can tap the Modify button to modify the relevant network configuration. DHCP and static IP configurations are supported. If you want to modify the configuration, tap Modify.

• DHCP: DHCP is the default and most common protocol. It is a network management protocol used on Internet Protocol (IP) networks to automatically assign IP addresses and other communication parameters to devices connected to the network using a client-server architecture.
• Static: If you need a fixed IP address for connection, or if you want to manually configure network information (such as IP address, gateway, netmask), you need a static IP configuration.

Wi-Fi

Wi-Fi allows you to connect your device to an existing wireless network.

To enable Wi-Fi, toggle Enable to on. The device will automatically search for nearby available Wi-Fi networks. Tap Scan Wi-Fi in the upper-right corner to search again for nearby available Wi-Fi networks.

Tap the Wi-Fi you want to connect to and configure it.Enter the corresponding information in the pop-up window. (If the network you want to connect to isn't listed, or if the network you want to join is hidden, tap Other at the bottom).

Tap the Advanced Settings button. In the Advanced Settings, there are two functions: Lock BSSID and Manually Set static IP.

• Lock BSSID: If this option is enabled, the device will only connect to the Access Point (AP) corresponding to the BSSID you selected when switching to a network using this SSID.
• Manually Set a static IP: Set a static IP address to enter the IP address, subnet mask, and gateway in the corresponding input fields.

Note: The device supports saving up to three Wi-Fi configurations.

When you save Wi-Fi networks with the same SSID and the same encryption method in the list, only one of them will be retained.

If you have three saved Wi-Fi configurations, adding a new one will replace the oldest one in the list.

• The MAC filter input rules are as follows:
• Case-insensitive;
• Multiple MAC addresses distinguished by line breaks;
• A single MAC address can be split by the characters ":" and "-";
• Example of a MAC to match: 112233445566
• Prefix matching (needs to start with ^ followed by 1~12 hexadecimal characters) e.g. ^112233
• Suffix matching (needs to end with $ followed by 1~12 hexadecimal characters) For example 445566$
• Match anywhere (1~12 hexadecimal characters only) For example: 334455
• Exact match (supports regular writing format) For example: 112233445566/11:22:33:44:55:66/11-22-33-44-55-66
• Raw data filter: If you tap the settings icon, the configuration of the raw data filter will take effect when the switch is on. If the switch is off, the configuration in the filter will be disabled.
• The raw data filter supports all regular expressions and requires you to enter the data you want to match in hexadecimal format.
• If you need an exact match with the field you want to enter, add "^" and "$" before and after the field, for example, ^616263$.

Note: In extended mode, the size of a single packet is limited to 256 bytes.

Synchronize Mode

• Skip parameter: This parameter specifies the maximum number of consecutive periodic broadcast events that the receiver can skip after successfully receiving the periodic broadcast packet, in the range [0, 499];
• Timeout period: This parameter specifies the maximum time allowed between successful receptions. If this time is exceeded, synchronization will be lost, range [10, 16384];
• Configuration list: Up to 4 periodic broadcast devices can be synchronized on this list. Each synchronized device needs to provide three parameters: the device address type, address, and SID.
• Address type: Public address and random address can be selected;
• Address: The MAC address of the device to be synchronized, which is required to be filled in with a 12-character MAC without ":" format;
• SID: Used to identify periodic broadcasts, range [0, 15];

After completing the configuration and ensuring that the Bluetooth scanning functions are enabled, tap the refresh button at the bottom-right corner to obtain the broadcast packet.

On this page, the current firmware version and firmware type will be displayed.

Under the Available Firmware column, you will get the official firmware type and version that is currently supported, and you can select the corresponding version and firmware type to upgrade.

At the same time, the reserved system configuration can be upgraded by simply turning on the "reserved configuration" button. However, for upgrade toggles of different firmware types, select "Do not keep the configuration".

Local upgrade

The local upgrade is based on HTTP, and you can manually select the firmware type you want to upgrade.

• If the firmware type is GL-S20-BLE, you need to upload the APP and RCP firmware in the specified file box.
• If the firmware type is GL-S20-OTBR, you need to upload the APP, RCP, and Web firmware in the specified file box.
• Please control the size of the APP firmware within 3M, the size of the RCP firmware within 2M, and the size of the web firmware within 4M.
• The same type of firmware supports reserved configuration upgrades, while different firmware types do not support reserved configuration upgrades.
• Through local upgrade, users can use the firmware written by their own design, but pay attention to the firmware size and partition table division.

URL upgrade

The URL upgrade is used for a custom http server. Place the firmware to be upgraded in the target http server. The firmware storage path must be based on the following rules:

• To upgrade the GL-S20-BLE firmware type without web, make sure that there is no web.bin under the path.
• Assume that the URL path of the HTTP server is http://gl-s20-ble/
• For app.bin firmware, store the firmware in the http://gl-s20-ble/app.bin
• For rcp.bin firmware, store the firmware in the For rcp.bin firmware, store the firmware in the
• For upgrading the GL-S20-OTBR firmware type with web, make sure that there is a web.bin in the path.
• Assuming that the HTTP server URL path is http://gl-s20-otbr/)
• For app.bin firmware, store the firmware to http://gl-s20-otbr/app.bin
• For rcp.bin firmware, store the firmware to http://gl-s20-otbr/rcp.bin
• For web.bin firmware, store the firmware to http://gl-s20-otbr/web.bin

URL upgrades also support reserved configuration upgrades, but for upgrade toggles of different firmware types, select Do not retain configuration upgrades. You can use the firmware of your own design and writing by URL upgrade, but pay attention to the size of the firmware and the partition table division. If the designed firmware contains a web page, please store the firmware on the HTTP server as a web strip.

The URL upgrade supports HTTPS. When the URL prefix entered in the input box is HTTPS, the certificate update page will pop up.

There are two ways to update a certificate, one is to upload the certificate file locally, and the other is to obtain the certificate through the URL.

After the certificate is uploaded, you can perform a firmware upgrade over HTTPS.
