These two have a certain correlation, so put them together.

Note: Most people do not need this function. It is designed for those who do not use Bluetooth for a long or short period of time. If you need to save battery manually in daily use, please use Lock Mode.

Because the physical switch on the keyboard is just a battery power switch. Even if it is turned off, when the USB cable is plugged in, Bluetooth will still work because of the external power supply from USB.

So in the latest firmware, a Bluetooth Function switch is introduced. You can use it to completely turn off the Bluetooth function of the keyboard. (This setting will be saved after restart)

Note: This feature is currently in beta and only supported by some keyboards. Details may change in the future.

You can set a key to turn Bluetooth on and off, as shown in the pic below. Or just use the short keys LShift+RShift+W to toggle it.

After Bluetooth Function is turned off, the Bluetooth part of the entire keyboard no longer works. It is also recommended to turn off the battery switch at this time.

To tell if Bluetooth Function is off, there are several ways:

1. Every time you plug in or turn on or off the power, there is no longer Bluetooth connection status indication.
2. When using the keyboard with wire, LShift+RShift+S will not show the Bluetooth connection status indication.
3. Use Output battery level in text function, the result is 12 and never update.

Because the Bluetooth part is not working, when you turn off Bluetooth Function, if you do not plug it in, you ca n’t turn on Bluetooth again. To turn Bluetooth Function on:

1. Plug in the USB cable and turn on the Bluetooth Function by pressing LShift+RShift+W.
2. Refer to the method of wake up from Lock Mode (press F and J at the same time), you can turn on Bluetooth Function without plugging in the USB Cable.

Method 1 is suitable for all BLE series keyboards, and some keyboards of method 2 are not applicable.

The Bluetooth connection status is only displayed when the Bluetooth Function mentioned above is turned on.

It is automatically displayed at each startup and other power state changes. It is also displayed when waking up from deep power-saving mode.

From this indication, you can confirm whether the keyboard is started normally and wake up normally.

Different keyboards display Bluetooth connection status in different ways.

The LED light flashes quickly when not connected (the longest time is about 15 seconds the it goes off, and it can be terminated manually by LShift+RShift+S. After connected, its led light flashes slowly and will be off about three times flashing. If it is an RGB light indication, the colors are also different in the two states. For details, refer to the description of each keyboard individually or the table at the bottom of this article.

While using the keyboard, you can also use LShift+RShift+S to manually check the Bluetooth connection status.

Because of the limited indicator leds, some keyboards that indicate Bluetooth connection status overlap with low-battery indicators. Give priority to low battery, only when the battery is not low, the Bluetooth connection status will be displayed.

The BLE series keyboards that have supported this function are shown in the table below:
