System Key

System keys are designed for switching keyboard modes, settings, and other purposes. Currently, the functions related to system keys are fixed (customization may be available in the future).

Please refer to the table below for the current system key descriptions and modes:

	Short Press	Long Press
System Key 1	Switch between Normal/Key Display Mode	Sleep Mode
System Key 2	Turn off screen display	Lock Mode
System Key 3	Switch between Bluetooth/Wired Mode	Switch between Normal Mode/WiFi Mode
Pressing System Key 1 + 2	N/A	Long press for 5 seconds to reset key mappings

Here are the explanations for various special modes:

Mode Name	Mode Description
Key Display Mode	Pressing a key will only display the key information on the screen without actually triggering the key. This mode allows you to quickly check the functions assigned to each key.
Sleep Mode	Enters low-power deep sleep and ends any connections. You can wake up the keyboard by pressing both sleep/wake keys (it is not a complete shutdown).
Screen Off Mode	Completely turns off the OLED screen. If not in sleep mode, the status indicator light will display the keyboard status. (In normal mode, the screen will automatically enter protection mode after a period of time, and any key can light up the screen)
Lock Mode	Once in lock mode, the keyboard will not automatically enter sleep mode (it will also not enter sleep mode in wired mode).
WiFi Mode	This mode is required for key mapping and other operations. You can configure the keyboard through other devices on the same network.

Left/Right Toggle Switch

There is a left/right toggle switch below the main knob, which is mainly used to switch between layers/layouts.

By toggling left or right, you can quickly switch between different layers, and a single click will quickly return to the initial layer (Layer 0).

System Indicator LED

The system indicator LED is located above the main knob on the right side and is used to display various keyboard statuses (it will turn off to save power in normal situations).

Keyboard Status Indicator LED Color	Status Description
Flashing Blue	Bluetooth is waiting to connect
Solid Green	USB is connected/charging
Flashing Red	Battery is low

Keymap Update / Customization

What You Need

1. A tablet/computer with keyboard input capability and WiFi.
2. Chrome/Edge browser (Firefox is currently not supported).

Operation Instructions

1. Open the browser on your tablet/computer and go to the configuration webpage: https://blog.driftking.tw/Schnell-Keypad-Configuration-Tool/.
2. Long press System Key 3 to enter WiFi mode.
3. After successfully entering the configuration mode, the screen will display network connection information.
4. It will automatically search for and attempt to connect to the previously configured network.
5. If it fails to connect to the previous network, the keyboard will enter AP mode. You can connect to the "Schnell Keypad WLAN" with another device to establish a connection with the keyboard.
6. The password is the same as your WiFi password. If not set or after firmware installation, the default password is 12345678.
7. Follow the instructions on the webpage to complete the necessary key mapping settings and click "Upload Configuration" to upload the configuration file to the device.

There are two ways to achieve this:

• Wireless Method: 1. Connect to the Schnell Keypad WiFi AP as mentioned above. 2. After successful connection, open the browser and go to the keyboard's local configuration webpage: http://schnell.local/ (It may take some time for the first use and allow the browser to access "insecure content"). 3. If connected in AP mode, update the network settings on the right side (only supports 2.4GHz WiFi networks and must be in the same local network as the configuring device).
• Wired Method (only for computers, the keyboard needs to be in WiFi mode for wired configuration): 1. Connect the keyboard to the computer via USB cable. 2. Open the browser and go to the configuration webpage: https://blog.driftking.tw/Schnell-Keypad-Configuration-Tool/. 3. Click "Install Firmware" on the webpage. 4. A dialog box will appear, select the device starting with "ESP32-S3". 5. Click "Connect". 6. After successful connection, the firmware dialog box will appear. 7. Choose "CONNECT TO WIFI". 8. Follow the prompts to select the desired hotspot for connection. 9. After successful connection, the WiFi settings are completed.
